QUESTION: I have a 1983 CJ-7 with a 258 six. It has a T-5 five speed transmission with (I believe) a Dana 300 transfer case. The transmission blew apart and I need to change it out. Do I have to change the transfer case too or will the Dana 300 bolt up to a Jeep 4 speed? The front axle pumpkin is on the passenger side as you look at it from the front.
ANSWER: Your Jeep should have a Dana 300 transfer case and since you mentioned that it has a 5 speed it’s about 99.9% sure that it’s a Dana 300. Yes a Jeep 4 speed from similar years will bolt to both the engine and transmission without any special adapter. The problem will be is that most of the Jeep 4 speed transmissions are shorter in length which will cause the rear and front driveshaft to not fit without modification. There may be other differences like where the shifter and transfercase shifter comes through the floor. Funny how a minor change can open a big can of worms.
See the Jeep Transmission Tech section for specifics on transmissions.
