Questions: Which grade of trans/transf case gear lube is best for a 42 GPW? Should I use a GL-4 or a GL-5 80/90 lube. the former owner used GL-5 80/90 thanks.......
Question By: Phil Lauricella on Jun 3 2018 10:16 PM
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.

Questions: I'm weighing in the option of picking it up or shipping it overseas. What is the weight and dimension of the package to be shipped; and will be packed into a wooden crate?
Question By: Alex on Aug 14 2013 12:00 AM
These come in a heavy duty double walled box with packaging. The box is approx 18x12x12 and weights 50 pounds.
