Questions & Answers
Questions: I have a 1966 CJ5 with the T86 transmission. It was recently rebuilt but keeps slipping out of first gear. I believe its the top end springs and balls that are worn but don't know. I realize parts for this are obsolete. Will this T-90 top fit the needs or do you have another idea

Email email@example.com and we can help. It could be your poppet balls and springs.

Questions: I rebuilt my t90 transmission it was jumping out of 2nd gear replaced the gear and syncro put in new rebuild parts now it is coming out of second gear on occasion. I am wondering if the tower needs replacement or rebuilding. In the past I have solved the second gear problem with a rebuild I know sometimes jumping out of gear is the tower. any suggestions.
Question By: john carothers on Sep 26 2018 2:35 PM
I would check your shift forks for wear for sure. If youve already replaced 2nd speed gear its the next place to look. Also your poppets.

Sell your Transmission to someone who wants a column shift then buy another T90. I think you have what is called the T90J, very cool.

Questions: The shift cane appears to be of equal diameter from tranny to shift knob, is that correct? It looks odd -- all 2A canes I've ever seen were tapered down going up the upper half of it.
Question By: George Mace on Mar 4 2018 2:14 AM
They make the new cane shafts heavy duty. They were originally tapered.

Questions: On my 55' T90A I've had leaks from the trans cane tower & back of the shift rails even when I fill only to below the transmi fill hole.. On your "TRANSMISSION TOP SHIFTER ASSEMBLY" is there an upgrade to resolve this? Do I see what looks like a vent, a fill plug & are those rear shift rail plugs? Thanks Jax
Question By: Jax on Mar 25 2017 2:24 AM
That is from a build up of pressure. I have had people drill a small vent hole in the freeze plug to prevent this.

Questions: I have replaced the synchronizers, and second gear looks serviceable. But I'm not getting full gear engagment, could it be something fixed by replacing/rebuilding the tower?
Question By: Sam on May 28 2013 12:00 AM
I would check for wear on your poppet balls and springs as well as for wear on your shift forks in the tower.

Questions: what is the thread pattern on the stick for the shifter knob?
Question By: Colby on Apr 19 2013 12:00 AM
I think it is 3/8 but would have to confirm. They screw right on to the original cane shaft.
Answer By: Willys Tech on Apr 22 2013 12:00 AM
I recently purchased a new T-90 shifter knob from Kaiser Willys and the threads inside the knob are 5/16" fine thread.

Questions: My shifter assembly is leaking oil at the rails. Is this an indication of a problem? Will the shift rail caps fix the problem? do you sell those separately?
Question By: Aaron on Aug 17 2011 12:00 AM
Sounds like it may be overfilled but it shouldnt be a problem.
Answer By: Willys Tech on Aug 18 2011 12:00 AM
Questions: What are the two silver knobs on the assembly for? IS on of them a vent? The one I have doesn't have either knob but does have the plates attached on the end of the shifter rails to keep them from leaking.Does this assembly fix that leaking problem or do you have to put the plates back on?
Question By: Anonymous on Jun 13 2011 12:00 AM
Those are just free plugs for the shift rails. You wont have any problems with leaking on these.

Questions: I replaced the top shifter on a T-90 transmission for a 1964 CJ-5 Willy Jeep. In first gear, the shifter stick is all the way to the dash and I would like to adjust it so the dash does not almost get hit every time when I start the Jeep moving. How do I adjust the shifter motion range farther back so when it shifters, the shifter stick is not hitting something?
