Hello all,

Will a TH400 Automatic transmission fit my 81 or 83 CJ7?

I believe that tranny is to long. The drive shaft angles become to extreme.
 
I stand corrected. I always thought that combo was to long for a CJ. :confused:
 
AWESOME!!

Thank you BusDave9!!!

This is going to make my life much better.

P.S. you might be able to answer this questions; I will owe you some beer if you ever come to Zion National Park in Utah....

I have a 1981 CJ7 258 with a 4 speed; that I want to put the 4 speed into my 1983 CJ7 304..Will this work?
 
You can ALS use a th400 short output shaft and the factory skinny adapter for a 205 they fit as well. If you go the 400 rout let me know the 1-2 shift while still in 1 really "@():$) but its a free fix.

No, probably not. It depends on your driveline. The 304 was not offered in '83. It must have been swapped in. The 304 is from the '70s and I am willing to bet the tranny and maybe the TCase are also from the '70s. If your '83 has a Dana 20 TCase then it will not be easy to install without 2 adapters.

The answer is maybe and there are a lot of variables. You might want to start a new thread.
