Multiple truck freight parts on an order may increase the shipping amount. Step 4: Locate the correct three-tang thrust washer for the front planetary carrier. Step 4: Clean and inspect the oil pump gears, as well as both halves of the oil pump assembly. Inspect the governor gear closely for wear or damage. I can't tell you first hand but there are many that swear that a 350 built just right is even stronger than any 400. The stock thrust washer was probably plastic; the replacement should be metal.
Step 2: Install the O-ring on the housing. This three-speed medium-duty automatic was used primarily with six-cylinders and small-block V-8s. Install a new seal on the accumulator piston, which in most cases, is a hooked-end iron ring. Make certain that the shifter is in Park, and verify that the parking pawl is engaged before you attempt to start the vehicle. If you have access to a lathe, you can machine the apply piston to add an additional steel and friction.
Remove the backing plate, frictions, and steel plates. Direct Drum Bushing Installation Step 1: Drive the bushing out as shown with a long tapered punch. Step 2: Note the small shaft on the underside of the forward clutch. Bishop I definitely recommend a look at these transmissions, you've got to have a look. A 4L80-E can handle more torque than a 4L60-E. The basic rules for transmission building apply to all units. Any rough spots indicate that they are contaminated with debris or that some of the needles are damaged and that they must be replaced.
Written by Cliff Ruggles and Posted with Permission of CarTechBooks. Regardless, the torque converter should spin freely when the transmission is bolted to the engine. Determine if the filler tube needs to go in before lifting the transmission into place, or if there is room to install it afterward. At this point, turn the engine with a large socket on the front of the crankshaft, or with a large flat-blade screwdriver between the bellhousing and flexplate teeth. There should be a 6 digit on the right vertical face of the pan.
To help guide the transmission onto the engine, make a couple of guide studs. Step 3: Once the center support is pushed into place on the case lugs, install the retaining ring as shown. I absolutely couldn't find any numbers anywhere on the bellhousing. Step 5: Use a small screwdriver to test for full movement of the modulator valve. Place the transmission on the jack and secure it with a chain or strap.
Speedometer Installation Carefully inspect the speedometer drive gear for wear and cracks. It should turn freely without binding. This requires that the spring compressor must have the ability to accommodate the input shaft and still compress the spring cage. Slowly tighten the bolts evenly and pull the transmission until it is fully seated against the engine. Step 5: Install the snap ring over the retainer.
Once they are well lubricated, turn them by hand and feel for any roughness or tight spots. Step 8: Install the backing plate over the last friction. This transmission was very popular due to its strength and versatility, as is still used in many vintage cars to this day. Check the fluid level once again, and add as needed. The accumulator cover is a small, round dome-shaped cap, located in the middle of the transmission. Set it on the end of the output shaft. Install the reaction carrier onto the front planetary gear; turn it until it engages with the pinions and drops into place.
Use the adjusters on the transmission jack to keep the transmission well aligned with the engine. Note the location of the retaining spring in the case. Step 3: The case bushing is driven in from the front. When it shifts from 1st to 2nd its got a really smooth shift and it puts a smile on your face. Notice that even though it's still a 6 bolt pattern the second hole up from the bottom on both sides is for a guide pin, not a bolt it's wildly different from the later 'standardized' patterns.
So, although it carries the Turbo Hydra-matic name, the Hydra-matic Division of General Motors had little, if anything, to do with its design. Do not force the piston into the bore or you may break the sealing ring. The input shaft is attached to the drum. Step 2: Install the 1-2 accumulator spring. Generally used in straight and V6 and small block engines.
