Questions & Answers
Questions: I just bought a '42 mb and it has a T90 transmission in it. All things equal and working, should I keep this transmission in it or trade it out for a T84? I plan on using the mb for fun and hunting instead of buying a side by side quad.

Questions: I am looking to purchase this for a friend who is restoring a 1943 Willys in France. Although I am located in California I was wondering if you would be able to ship directly to France and whether you were familiar with the import duties there. Please let me know thanks.

We use a straight GL-4 non synthetic. They are good for yellow metals.

Questions: I have a restored 42 Willys MB. Transmission was making noise in 2nd gear. A mechanic sent the transmission to transmission shop and they said they had to build up the main shaft and turn it down. Now it makes severe noise in 3rd gear at all speeds. I complained and they sent the transmission back and said it was normal. I have owned several Willys Jeeps, this does not seem right. I have been out some serious money allready. What do you guys suggest. Thank you, Ralph Todd

Doesnt sound right to me. Some gear chatter is normal in the transmission and transfer case but from what you write that sounds excessive. Call me toll free. Ask for Mike M. I can try to help out.

Questions: Does the t-84 and t-90 use the same transfer case ? I just bought an mb frame and motor i put a t-90 trans to the back and its 1 1/2 inches to long if i get a t-84 trans will it work with the transfer case i have ?
Question By: Bill on Sep 21 2014 12:00 AM
No, the transfercase between the two are different. T-84 used a 3/4 intermediate shaft and the T90 used either a 1-l/8 or 1-1/4 intermediate shaft all with different gears from one another. This link will help: http://www.kaiserwillys.com/category/willys-jeep-transfercase-diagrams

Questions: I have a 45 gpw that has a t90 swap. I am doing a frame off restoration And would like to go back to a t84 so I don't have to cut the floor. What are the dimensions of the t84 vs t90?
Question By: Travis on Jun 28 2014 12:00 AM
The T84 sits lower than the T90 because of the top shifter. I imagine that someone had to cut your floor board to make the T90 work in your jeep.

Questions: On my t-84 transmission, it won't shift into first gear while vehicle is in motion. Is this normal or do I have a problem?
Question By: Steve on Nov 4 2013 12:00 AM
You shouldnt be able to. It is not sycronized.
