Transmission

Task: Inspect And/or Rebuild Transmission

Removed Transmission to inspect and take to shop if required. It was very dirty and needed to be inspected to ensure it worked properly. Removed with floor jack after I removed the four front bolts connected to the bell housing. This allows you to also inspect the clutch assembly and throw out Bearing.

Ensure you get a quote before you let the Transmission shop repair as this can get costly. Replace all fluids with new GL-1 Trans Fluid when the transmission is out and on the floor upon return from shop. It was completely rebuild and is ready for installation once the drive shaft and u-joints are checked. Have some help with installation as the transmission is heavy and you need a proper transmission hoist and/or jack adapter to properly ensure you don’t drop it to the floor.

Task: Replace Broken Transmission Shift Linkage Rod

Reason: The one that was found with the truck was broken

Rather then buying a new shift rod for the T-85 Transmission I took a spare NOS Shift Rod and put in a vice to bend it the same way the broken one was shaped. I matched up the new rod and installed it with a new swivel, washer and cotter pin. The NOS Transmission Rod was the same as the broken one in length except it was bent for use in another Transmission/vehicle model

Task: Install T-85 3 Speed Overdrive Transmission

I proceeded to re-install the transmission with the help of another person. His main job would be to assist me in getting the heavy Transmission lined up. I used my floor jack with a specially build wooden platform so the transmission wouldn’t move when I moved it into place. It is a very tight squeeze as the Governor is very close to the underbody of the cab and first thing to do is to insert the Input gear into the Clutch Throw-out bearing. This is brute work and as you get the imput gear shaft into the Throw-out Bearing you need to turn over the imput gear over to mesh with the splines in the clutch plate and be able to get fully home into the bell housing and clutch assembly. We used two longer bolts of the same size as the transmission mounting bolts so we could draw it closer to the bell housing while lining up the imput gear through the clutch plate. We were able to line everything up and re-insert the four transmission mounting bolts while re-torqueing them. We then re-attached the two gearshift rods to the transmission ensuring that is attached properly as per manual. Used a nail to go between the two holes in the steering column gearshift levers to ensure it was properly aligned and had shifting ability. Once both rods were connected I removed the nail and verified that I could go through all of the gears on the column shifter. I also installed a rubber governor boot (Part # 522022) to help keep the governor clean and protected.
