Questions: my 52 m38a1 makes a moderate whine/grind when driving that goes away when clutch is depressed I was told by a mechanic friend that it's probably the throw out bearing.... Is that a possibility? And does this minor kit have that?.... Thanks
Question By: Dom on Mar 4 2015 12:00 AM
Your throw out bearing is in your clutch part number: 635529

Questions: Hi, I purchased a 61 cj5 with 2nd gear snycros out or so I was told. I rebuilt the trans and it worked fine for a few days except it would kick out of 2nd when decelerating then lost 2nd gear again. Upon taking off the top cover I saw that the top set of gears had moved back and would not allow the gears to mesh. I purchased syncro set and a few more parts to make sure everything stayed in place. But when finished even though shifter locks into 2nd the trans just grinds. Any ideas, thanks
Question By: David on Aug 16 2014 12:00 AM
It could be your 2nd speed gear itself as well. I would check it for wear as well.

Questions: I have a 63' that keeps popping out of first gear when going down steep hills in 4 low also I'm having troubles locking in the hubs, any ideas?
Question By: Mark on Jan 13 2014 12:00 AM
It is probably your poppet balls and springs. I would check those for wear.

Questions: I'm intending to overhaul the T90a1 and T18 in my CJ-3B. Can you tell me who made your overhaul kits. Can you tell me who manufactured the main bearings or where they were made (China, Japan, USA?). thanks for your time.
Question By: Carl on Jan 28 2013 12:00 AM
We have them done by our professional rebuilder. The bearings are US made.

Questions: I have a 1960 Willys Jeep Truck w/a 6-226 flathead in it. I am looking to overhaul the transmission and transfer case and am wondering if any shims are required on either one and if so do they come in the minor overhaul kit. I believe all the gears and shafts are in good shape but both need new seals and the transmission is making what sounds like front bearing noise. Thanks. MB
Question By: Marc on Mar 19 2012 12:00 AM
The only place there really are shims is on the rear output of the transfercase. This is a great kit that will take care of most of your problems.

Questions: I am getting a Jeep with a T90 3 speed in it, but the high and low gears do not work only the reverse does. Do I need a complete rebuild or is it something simple?
Question By: Sean on Feb 14 2012 12:00 AM
Sounds like it is your syncronizer. I would start there. We have them part number: 640391
Answer By: Willys Tech on Feb 15 2012 12:00 AM

Questions: Does this kit T90BSG (Minor overhaul kit)come with synchronizes?
Question By: Bill on Mar 23 2011 12:00 AM
No, it does not come with syncro parts. Try part numbers: 640394, 640395 & 640397. If you want the complete syncro it is part number: 640391
