If used, install any waved or selective steels first, then start with a new steel plate, friction plate, and continue until you have installed five steels and five frictions, ending with a friction. Inspect clutch packs for worn linings, or damaged or worn steel plates. Install the upper bushing with the chamfered inside edge facing upward. Inspect the sealing rings, bushings, thrust washers, and Torrington bearings. Most transmission shops will install the seals for you for a small fee so you can avoid buying the tools. The planetary gears are still interchangeable between years, and transmissions made in or after 1987 may still contain the holes for the thrust washer, even if it isn’t used. Remove the front planetary, reaction carrier, sun shell, and sun gear, noting the location and orientation of the Torrington bearings and thrust washers between these components. The TV cable provides the reference signal to the transmission. The tail housing is next. It sits directly on the apply spacer. Install the inner sprag race while turning it clockwise and pushing down at the same time. Last on the list is to remove the servo assembly that applies the band.

Both electronic and non-electronically controlled units will have a wiring harness under the oil pan. Install a new thrust washer on the race, retain with TransGel. The new onepiece seals are pushed into position over a plastic guide, and then resized. Install the correct Torrington bearing under the low/reverse planetary gear, and install the planetary. I use an old two-burner gas stove, and heat the case for about 10 minutes. Install a new seal inside the input drum and place the Torrington bearing in position as shown.
