Rusty’s T-96 Transmission Rebuild

• CATEGORIES: Builds, Features • TAGS: .

Another thing I got accomplished recently was the rebuilding of Rusty’s T-96 transmission. It’s been a couple decades since I’ve rebuild a T-90, but I think a person could follow a T-90 side shift guide when rebuilding the T-96 (I didn’t think of this until after I was done — instead I used an old rebuild manual from the late 60’s that has rebuilds of 35 different styles of transmissions). Once again, I thought I had more pics, but I didn’t. So, this isn’t a step-by-step overview.

I took this photo at the beginning of the tear-down to remember which way the speedometer gear should face. The lack of a transfercase is part of what makes this rebuild different from most other jeep transmissions.

Here’s the transmission with the input shaft pulled forward. My first gear and second gears were a bit worn. 2017-05-20-transmission2

Once I removed all the gears, I discovered the reverse gear had a broken tooth. 2017-05-20-transmission3

Close up of broken tooth. Thankfully, Charles Tate had sent me a box of T-96 parts that included a reverse gear. I was also able to replace the entire bottom cluster, first gear, and second gear. That saved me some money!

To remove the side shifters, a pin has to be tapped out. I was able to remove the 2/3 gear shifter, but not the first/reverse unit. Since there was no critical reason I could see for removing the first/reverse mechanism, I left it as is and cleaned up the housing.2017-05-20-transmission4

Normally, I’d paint the housing before assembly. However, with time being an issue and lacking enough warmth on the rebuild day to properly paint it, I will paint it at a later date. 2017-05-20-transmission5

One other unique thing about the T-96: it requires the use of a special speedometer cable that is also used for Jeepsters and wagons.

    Hi Rusty, I have a T-96 from a Gibson tractor . 46 or 47 I think. it was left outside under a tree for 25 plus yrs so water got in through the shift tower. I got the aenl Wisconsin back together and runs and starts like a new one. my question is are you familiar with T 96’s set up for a Gibson? mine is in pieces or id send you pictures, the input shaft has a collar on it for a 48 teeth # 50 chain drive and the tailstock is short w/no speedometer gear hole. any help is greatly appreciated. the cluster, input shaft, reverse gear, syncros, 1 st & 2 nd gear is all kaput. the only decent parts still good are the case and main shaft from the rear.

    Hi Norman,

    I want to apologize for missing this comment. I see that you asked a question about the T-96 on April 22. I am not familiar with how the t-96 was used in a tractor.

    I did some research. Based on this website ( http://www.tractorfriends.org/lawn&gardentractors/gibsontractors/Gibson%20Tractors.html ), the T-96s are the same. Quoting the post:

    “A number of tractors were issued with Chevrolet transmissions and Plymouth differentials; however, others were used as available, including Borg-Warner T-96 transmissions–the same as those used in Willys Jeeps, AMC, Crosley, Ford-Falcon, and Studebaker automobiles, and Economy Power-King garden tractors, amongst others.”

    The above quote suggests they are the same, though it’s possible that the principal shaft is different.

    On April 27 you asked a second question about the tower. Given the quote above, it seems plausible that your tower might work, but I have never tried adapting a tower to the T-96.

    If the tower in fact works, it would be something I’d like to report to eWillys readers. Someone might find such a conversion useful.

    Sorry I can’t be more help,

    – Dave

    I have a T-96 trans out of a 49 Jeepster an looking for the shift rods that go to the trans to the steering column. Do you have them or now were i could get a pair

    Paul,

    I’d try the https://www.thejeepsterman.com … they might have what you need. Note that as I understand it, the shifting rods were slightly different between the DJ-3As and the Jeepsters. Whether the Jeepsters and the CJ-2A column shifters were the same is not something I know offhand.

    I have a 1950 Jeepster with a T96. Not shifting correctly, and after multiple adjustments to the shift rods (also replaced the bushings that fit in the fork levers), I am still not satisfied with it. Shifts up OK, but no way to shift from 3rd to 2nd. Even shifting up, I hear a little gear noise. Also adjusted the clutch.

    Question….I plan to take it apart to see if the synchronizers are bad. Can’t find any dedicated service info on this. Might someone have a manual I can get a copy of?

    Thx

    Vic,

    This link provides an exploded view of the transmission: https://www.kaiserwillys.com/t-96-transmission

    Unfortunately, I don’t have the vintage transmission booklet with me (it’s about 200miles away from me) that included the directions on how to rebuild this. I looked for a rebuild guide on the web, but couldn’t find anything.

    My feeling is that the T-90 rebuild is pretty similar:

    I hope that helps.

    BTW, does anyone have a Borg Warner parts list for a T96. Like to cross reference Willys part numbers with BW

    Thx

    Thanks for your thoughts and suggestions. I do have the T96 Willys part numbers, but some of the transmission parts suppliers I have contacted can’t cross reference them. These guys often have parts at 50% to 70% less then the Jeep sites, and I like to try them for parts.

    I was thinking that for the benefit of the group, if we could ever find a Borg-Warner parts list for these various transmissions, it would be an invaluable resource. I even reached out to Borg-Warner to see if there is anyone who manages their archives who might be able to help. If I find anything, I’ll post it.

    Thx
    Vic
