If an automatic was ordered, small-blocks were fitted with the T-350 and big-blocks came with the T-400. For a comprehensive guide on this entire subject you can visit this link: These included a 3-speed manual, close- or wide-ratio manual 4-speeds, or two automatic transmissions, depending on the buyer’s preference. Rebuilding an automatic transmission requires a lot of skill and patience. Many aftermarket suppliers offer rebuilt units on an exchange basis and usually include a warranty. (Photo Courtesy Cutaway Creations) At the end of C3 production in 1982 only a 4-speed automatic transmission was available. This included 3-speeds, 4-speed wide-ratio, and 4-speed close-ratio. They were built by Saginaw, Muncie, and BorgWarner. The only year a manual transmission was unavailable from the factory was 1982. The 3-speed was installed behind the standard 300-hp 327-ci engine in 1968 and the 300-hp 350-ci engines in 1969. Dealers used this basic equipment package to offer customers rock-bottom Corvette pricing. In 1968 a total of 326 3-speed Corvettes were built; in 1969 the number fell to 252 for this rare shifter. It was available in wide (M-20) and close ratio (M-21 and M-22). Muncie production ended in 1974 when it was replaced with units built by Warner. Here are the major components of a well-worn wide-ratio Muncie 4-speed transmission. It was originally installed in a 1965 Corvette. The basic design of this transmission remained the same from 1963 to 1974. The P code is stamped on the front lip of the case for identification purposes. This transmission will be completely overhauled and rebuilt with new gears, bearings, shafts, and shifter by Circle Products. They carried the option codes of M20, M21, and M22. These manual transmissions were optional or standard for all of these model year Corvettes. Muncies can be distinguished from other manual transmissions because their reverse lever is mounted in the extension housing instead of the side cover. http://carexline.ru/generic/uploaded/crown-tsp-7000-manual.xml

The main difference between the Muncie and the BorgWarner is that the Muncie has a seven-bolt side cover and the BorgWarner has nine bolts. This was the most widely produced transmission installed into early C3s. It was optional in 1968 (10,760 delivered) and 1969 (16,507 delivered). The M20 became standard in 1970 and started being phased out during the 1974 production cycle. It was replaced by the BorgWarner M20 wide-ratio 4-speed. This display simulating a Corvette on the St. Louis assembly line is at the National Corvette Museum in Bowling Green, Kentucky. The Muncie M20 wide-ratio 4-speed has been installed behind a 190-hp, 350-ci engine in this 1973 Corvette. (Note the shifter, shifting levers, and the reverse lockout cable.) The transmission is attached to the frame with two bolts on a bracket that bolts to the frame and to the transmission extension. The exhaust is also mounted onto this bracket. This completely refurbished Muncie is ready to be installed into a 1968 Corvette. The shifter has been installed prior to the transmission being attached to the 327-ci engine. The transmission is equipped with new gears, bearings, and synchronizers. Produced in low volume from 1968 to 1971, the M22 earned the nickname “Rock Crusher” because its straight-cut gears made a distinctive noise while driving. It was designed for maximum performance and could usually be found installed behind L88s and other high-torque big-block engines. Only 336 were installed at the factory. It was very popular with road racers and came with the same gear ratios that were installed into the M21 close-ratio transmission. By 1975, it replaced the Muncie completely. Called the Super T-10, it was offered as a close-ratio (M21) with a 2.43 first, 1.61 second, 1.23 third, and 1.00:1 fourth. The M20 wide-ratio version had 2.64 first, 1.75 second, 1.34 third, and 1.00:1 fourth. In 1975 it became the only manual transmission available for Corvettes. http://www.jfvtransports.com/home/content/eltron-p310c-manual

The side cover requires nine bolts to secure it to the case. Here, one of the shifting forks has been inserted into the gears in the front of the transmission. The W (indicating Warner as the manufacturer) is stamped at the rear of this case. Many common problems with this transmission, such as gear clashing and high shift effort, are probably due to improper shift linkage adjustment. If the shifter is loose it could be due to worn grommets in the shift linkage or loose shift levers. These are very robust transmissions and it’s always a good idea to check the linkage condition and make adjustments before digging into the transmission. During its last year of production in 1980 the L82 engine was only available with an automatic transmission. The 1982 output shaft on the TH350 used a 27-spline output shaft and had a 1-inch countershaft diameter. With the correct bellhousing that matches each transmission’s bolt pattern they are compatible with GM 327, 350, 427, and 454 Corvette engines. Then place a floor jack under the transmission while putting a piece of scrap wood between the jack pad and the transmission. Slowly lift the jack while observing if the engine or transmission moves up or down. Any movement indicates the motor and transmission mounts are loose; you need to tighten all of these bolts. If any of these mounts are separated replace the defective mount. Run the engine at idle with the transmission in neutral and the clutch engaged. Let the clutch out, wait about 10 seconds, engage the clutch, and put the transmission in reverse. A grinding noise indicates the clutch is out of adjustment or some other clutch problem. The shifting forks and synchronizers are prone to wear in these units. This causes gear rattle, difficulty engaging a gear without grinding, and the tendency for the gear to pop out of its position. Faulty clutch and shifter adjustment also impact shifting smoothness. https://www.cbiinc.org/images/cappuccino-microbiology-lab-manual-pdf.pdf

Shifting rods that are out of adjustment is also a common reason that a transmission is hard to shift. In 1968, Corvette’s automatics underwent a major redesign. The new M40 Turbo Hydra-Matic was introduced in two versions: the TH350 and the TH400. Both carried the same option code. The factory installed the correct transmission type based on the type of engine ordered. The former 2-speed Powerglide was discontinued in favor of this 3-speed unit. You can use the existing bellhousing and clutch with this conversion if they are in good working condition, which saves money. The new transmission is longer than the GM 4-speed so a shorter driveshaft is required to align with the rear differential housing. This conversion provides a huge increase in fuel efficiency. Only 2,324 were ordered in 1967, compared to 5,063 in 1968. This transmission was installed into all small-block Corvettes until 1981. It was also used in a wide variety of other GM products, including passenger cars and trucks. It can be easily modified and is a favorite among drag racers because of its performance and rugged construction. Automatic transmission fluid (ATF) is pumped through the unit to provide lubrication and pressure to the unit. The ATF enables the valve body to shift the transmission into the correct gear. Clean fluid and filters help extend the transmission’s life and provide positive shifting. Frequent heavy-duty use calls for frequent transmission fluid and oil changes. If you are experiencing any of these symptoms the modulator is a good place to start your diagnosis. (Photo Courtesy Cutaway Creations) The TH400 was introduced in 1968. In its first year of production it was only available for 390- and 400-hp 427-ci engines. The engineers were not certain it would stand up behind the 430- and 435-hp engines. After extensive testing in 1968 to strengthen it, the transmission became available in 1969 for all big-block engines including the L88.

Each transmission has an identification tag on the passenger’s side that includes its type and build date. This particular TH400 came from a Pontiac, so the bellhousing has two mounts on the top, which is different than for a Corvette. After the Tremec is installed, the engine operates at 1,900 rpm when traveling 70 mph. This adds life to your engine and greatly improves your fuel mileage. You will also notice how much quieter the car is during cruising. It weighs 120 pounds and is 21.75 inches long. Its case is cast aluminum and features a 2.52 fi rst, 1.52 second, and 1.00 third. It has a distinctive oil pan that is recessed on the right rear side of the case. It can be affordably rebuilt with better components. For example, shifter kits can provide quicker, firmer shifts with less slippage and reduced clutch heat. Aftermarket transmission rebuilders can provide options on how much your TH350 can handle.It tips the scales at 135 pounds and features a cast-aluminum case with a 2.48 first, 1.48 second, and 1.00:1 third. In 1969 a heavy-duty version of the Turbo 400 became available for the L71 (435 hp), L88 (430 hp), and L89 (L71 with aluminum heads). A Y code in the serial number identifies them. Each part is inspected and replaced if it shows any wear or damage. The torque converter can be seen at the left, and the valve body is also on the left. The case that is sitting on the right will be completely disassembled and cleaned of all its grit and grime in a high-pressure washer then pressure tested for any cracks prior to being rebuilt. The basket spins and hot steam cleans all surfaces until they are completely free of all contaminants. The case is then tested to make sure it has no defects before it is overhauled. The extra horsepower capability that is built into these refurbished transmissions requires the parts to be capable of handling this extra stress.

Clutches like these can be found in 350 and 400 transmissions and are very prone to wearing as the miles pile on. It is good practice to replace any parts that show wear. The smaller, higher pressure Gear Star torque converter is on the left. These smaller converters are designed to hold more pressure and can handle engines that produce up to 1,200 hp. The unit on the left is a Corvette TH400 and the one on the right can be used in a Buick, Oldsmobile, or Pontiac. The giveaway is the different mounting outline on the bell housing. Without fluid they weigh 135 pounds. Dyno testing is a great way to confirm the transmission’s capabilities under stress. During the dyno test the transmission is filled with the correct amount of fluid to check the mechanical workings of the transmission. The top connector sends fluid to the radiator to be cooled. The bottom connector receives fluid from the radiator that has been cooled. This pumping action is important to the health of these transmissions. Because these units produce a tremendous amount of heat, a good cooling system is vital. If an abnormalities are discovered the unit is sent back to the shop to correct them. The dyno test checks shifting, pump pressure, transmission temperature, and gear slippage. A printout of the unit’s performance is reviewed by the engineers for any potential issues before shipping. Each completed transmission is tested on the transmission dyno to ensure it meets the owner’s performance requirements. (Photo Courtesy Gear Star) It was the only transmission available and featured a fourth gear overdrive to help improve fuel economy. It featured a 3.06 first, 1.62 second, 1.00 third, and.70:1 fourth. The TH700R4 was strong enough for the 200-hp Cross- Fire 350 engine, but it could not support the higher horsepower levels as did previous automatics installed in earlier Corvettes. If it is correct check the downshift cable adjustment. Look for any loose or broken vacuum lines and correct as necessary. {-Variable.fc_1_url-

If any of these conditions occur remove the modulator vacuum line and probe it with a pipe cleaner to see if fluid is present. If it is, replace the modulator. It serves the same purpose as a clutch pedal in a manual transmission. When the speed increases, the converter spins and multiplies the torque inside the unit. It is important to understand that a one-way or sprag clutch is used in a torque converter. When the converter pins, it spins faster than the engine turns. When the converter slows as the engine speed decreases, it must “catch” or stop so the engine can drive it again. This sprag clutch design lets this happen. It allows the converter to race in one direction only and catches against the clutch in the opposite direction. If your transmission is full of clean fluid and is slow going into gear (or not at all), the problem could be the converter. The converter has engagement tabs and a spline. Use a couple of long screwdrivers and wedge one of them into the spline to hold it stationary. Try to turn the tab with the other screwdriver. It should freely spin in one direction and hold firmly in the other. If it doesn’t, the converter is faulty. This is rarely the problem because most pumps are very reliable, but a quick check is a good idea. The following is not a precise test because a pressure gauge should be installed, but it gives you the needed information. Wrap a rag around the fitting and place it into a container to prevent fluid from going everywhere. A sound pump sprays fluid under a fairly high pressure. If you don’t see a gusher of fluid, you have a pump problem. Be very careful when performing this procedure, and only run the engine a few seconds to prevent running the transmission dry. A plugged or dirty filter can cause low pressure problems. Click the button below and we will send you an exclusive deal on this book. Unfortunately, this is how we pay the bills and our authors.

But as this three-part video series from YouTube’s V8TV shows, swapping an LS V8 into a car that it was not originally meant for isn’t such an easy task. Like many restoration jobs, whether it be home or automotive, there are some unexpected twists and turns that make this seemingly straightforward swap a bit more complicated than one may expect. This was an elegant and rather innovative solution back in 1969, but the vacuum system is known to burn out over time, which they both had on the customer car in question. The V8TV guys turn to Detroit Speed for some help, which offers an electronic conversion for the headlights and wiper trap door, making them more reliable and easier to service. See? Things are already getting a bit complicated and we haven’t even gotten to the engine swap yet! They then have to weld in a newly designed transmission tunnel before they are able to drop in the engine and gearbox. We don’t want to take away from the three-part series, though, so check it out embedded below to see how this surprisingly complicated project comes together. We welcome your submissions. See here for details. The owner wanted to drive the car for a while and not have to worry about crawling up driveways, etc., and the lower profile tires make the wheel wells look extra-huge.

Engines and chassis components were mostly carried over from the previous generation, but the body and interior were new. This time it was a single word as opposed to Sting Ray as used for the 1963 - 1967 C2 generation. The name would then be retired until 2014 when it was re-introduced with the release of the C7.Executed under Bill Mitchell's direction, the Mako II had been initiated in early 1964. The resulting lower half of the car was much like the Mako II, except for the softer contours. The concept car 's name was later changed to Manta Ray.As before, the car was available in either coupe or convertible models, but coupe was now a notchback fitted with a near-vertical removable rear window and removable roof panels ( T-tops ). A soft folding top was included with convertibles, while an auxiliary hardtop with a glass rear window was offered at additional cost. Included with coupes were hold down straps and a pair of vinyl bags to store the roof panels, and above the luggage area was a rear window stowage tray. The enduring new body's concealed headlights moved into position via a vacuum operated system rather than electrically as on the previous generation, and the new hide-away windshield wipers utilized a problematic vacuum door. The door handles were flush with the top of the doors with a separate release button. Front fenders had functional engine cooling vents. In the cabin, a large round speedometer and matching tachometer were positioned in front of the driver. Auxiliary gauges were clustered above the forward end of the console and included oil pressure, water temperature, ammeter, fuel gauge, and an analog clock. A fiber-optic system appeared on the console that monitored exterior lights and there was no glove box. The battery was relocated from the engine area to one of three compartments behind the seats to improve weight distribution.The engine line-up and horsepower ratings were also carried over from the previous year as were the 3 and 4-speed manual transmissions. The new optional Turbo Hydramatic 3-speed automatic transmission ( RPO M40) replaced the two-speed Powerglide. The L30, a 327 cu in (5. 4 L) small-block V8 engine rated at 300 hp (224 kW) and a 3-speed manual transmission were standard, but only a few hundred 3-speed manual equipped cars were sold. The 4-speed manual was available in M20 wide-ratio or M21 close-ratio transmission versions. All big block cars had domed hoods for additional engine clearance with twin simulated vents and “427” emblems on either side of the dome. The new seven-inch wide steel wheels had F70x15 nylon bias-ply tires standard with either white or red stripe tires optional.Tire size remained the same, although this was the first year for optional white lettered tires and the last for red striped tires. Carried over from the previous year were seven available rear axle ratios ranging from 2.73 to 4.56. Standard ratio remained 3.08 with automatic and 3.36 with manual transmission. Exterior door handles were redesigned so the finger plate would actuate the door, eliminating the separate release button. Backup lights were integrated into the inboard taillights, headlight washers were added, and front grilles were made all black. Side-mounted exhausts and front fender vent trim were options for this year only. On the inside, revised door panels provided additional shoulder room in the C3's tighter cabin and headrests became standard. Steering wheel diameter was reduced from 16 to 15 inches to permit easier entry and exit, the ignition switch was moved from the dash to the steering column, and map pockets were added to the dash area in front of the passenger seat. Accounting for 57 of the cars, coupes with their removable roof panels, began a trend of outselling roadsters. An extended production cycle due to a labor dispute increased '69 volume. This was the last year for the L88 engine and the only year for the ZL1 option, which offered an all-aluminum 427 cu in (7.0 L) big-block engine listed at 430 hp (321 kW). Rare options: ZL1 aluminum block (2), J56 heavy-duty brakes (115), L88 engine (116), L89 aluminum heads (390). The large-engine Corvettes are extraordinarily fast and marginally civilized.”New were eggcrate grills with matching front fender side vents and larger squared front directional lamps. The previously round dual exhaust outlets were made larger and rectangular in shape. Interiors were tweaked with redesigned seats and a new deluxe interior option combined wood-grain wood accents and higher-spec carpeting with leather seat surfaces. Positraction rear axle, tinted glass, and a wide-ratio 4-speed manual transmission were now standard. The 350 cu in (5.7 L) base engine (ZQ3) remained at 300 hp (224 kW) and the L46 was again offered as a 350 hp (261 kW) high performance upgrade. New was the LT-1, a 350 cu in (5.7 L) small-block V8 engine delivering a factory rated 370 hp (276 kW). It was a solid lifter motor featuring a forged steel crankshaft, 4-bolt main block, 11:1 compression ratio, impact extruded pistons, high-lift camshaft, low-restriction exhaust, aluminum intake manifold, 4-barrel carburetor, and finned aluminum rocker covers. The new engine, making up less than 8 of production, could not be ordered with air conditioning but was fitted with a domed hood adorned with “LT-1” decals.One is the best engineering effort of America, the other of Germany.Big-block selection was down to one engine but displacement increased. The LS5 was a 454 cu in (7.4 L; 7,439.7 cc) motor generating 390 hp (291 kW) SAE gross and accounted for a quarter of the cars.This was the final year for the fiber optics light monitoring system, the headlight washer system, and the M22 heavy duty 4-speed manual gearbox. The small blocks available were the 350 cu in (5.7 L) base engine, which dropped to 270 hp (201 kW), and the high performance LT-1, now listed at 330 hp (246 kW). The LS5 454 cu in (7.4 L) motor was carried over and produced 365 hp (272 kW). The LS5 454 cu in (7.4 L) big block was again available and came in at 270 hp (201 kW). The urethane nose was chosen over Chevy's other alternative, a more protruding version of the previous metal bumper. The base L-48 engine produced 190 hp (142 kW). The L-82 was introduced as the optional high performance small-block engine (replacing the LT-1 engine) and delivered 250 hp (186 kW). The new hydraulic lifter motor featured a forged steel crankshaft, running in a four-bolt main block, with special rods, impact extruded pistons, a higher lift camshaft, mated to special heads with larger valves running at a higher 9:1 compression, and included finned aluminum valve covers to help dissipate heat. Duntov and the other Corvette engineers gravitate toward the big blocks because they like the torque. And granted, the 454s will squirt through traffic with just a feather touch on the gas pedal.All models featured a new cowl induction domed hood, which pulled air in through a rear hood intake into the engine compartment under full throttle, increasing power (but didn't show up in the horsepower ratings). 0-60 mph times were reduced by a second while keeping the engine compartment cooler.Underneath sat a box-section aluminum impact bar on two Omark-bolt slider brackets similar to the system used in the nose which allowed the Corvette to pass federal five-mph impact tests at the rear as well as the front. The new rear design was quite beautiful, and more up-to-date than the 60's shape that it replaced with the vast majority of enthusiasts embracing the new design. For the 1974 model only, casting limitations mandated left and right bumper covers with a vertical center seam. The anti-theft alarm key activator was moved from the rear panel to the front left fender. Tailpipes were now turned down as the new bumper cover eliminated the tailpipe extensions. We wouldn’t just change it for the sake of change. But when we made the rear bumper stronger, we made Corvette’s rear styling look different. The fanatical clientele that buys 30,000 of them a year can attest to that. And we'll attest to the fact that after 20 years, the Corvette is more than going strong.The radiator and shroud were revised for better low-speed cooling. The inside rear-view mirror width was increased from 8 inches (200 mm) to 10 inches (250 mm). For the first time, lap and shoulder seat belts were integrated, but only in coupes.Dual exhaust pipes were routed to a single converter, then split again leading to dual mufflers and tailpipes. Starting this year, tachometers were electronically driven. The Corvette began to be influenced by the metric system as speedometers now displayed small subfaces indicating kilometers-per-hour. 75's featured revised inner bumper systems with molded front and rear simulated bumper guards. The urethane rear bumper, now in its second year, reappeared as a one-piece seamless unit. This was the final year for Astro Ventilation. Power bottomed out this year — the base engine produced only 165 hp (123 kW) and the only remaining optional motor, the L-82, dropped an astonishing 45 hp (34 kW), managing to deliver 205 hp (153 kW). With no larger engine available, L-82 hood emblems began to appear on cars so equipped. Unchanged was the standard rear axle ratio for the base engine, which remained at 3.08 with automatic and 3.36 with manual transmission. This was the last convertible for the 1968-82 third-generation and only 12 of the cars were ordered as such.These steel floor panels weighed less than the previous fiberglass floor and reduced interior noise levels. Horsepower rose to 180 hp (134 kW) for the base L-48 engine; 210 hp (157 kW) for the optional L-82. To further reduce cabin noise levels, cowl induction was dropped in favor of the air cleaner ducted over the radiator, picking up outside air from the front of the car, thus reducing wind turbulence at the base of the windshield. The hood was carried over, with its cowl vent grille and induction system opening becoming non-functional.
