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.
