Transmissions

Is it possible to put an automatic in a CJ5. And which transmission can you use. I have been told that a Powerglide will work but has anyone done this.

Thanks

CJ5 was never offered with an auto because they are just to long for the short wheel base.

dammit.

i guess i don;t have to lay under and measure everything out then.

i have the stroker in my yj and tf999 i was going to pull out for my v8 swap and then drop into the cj5. you guys are saying no-go though, eh? i noticed no automatics came in cj5s from the factory and i figured that was why but i was hoping it was not true.

It's just as well. Putting an automatic in a CJ is like putting mayo on a hamburger...it just ain't right.

Sure they can. Myself and many others have ran th350's behind SBC's in CJ5's. You could do a th400, but the driveshaft is short enough as is with the th350.
Not sure what your intended use for the CJ is, but a powerglide may not be the transmission you'd want.

904 999 T350 any of them would work
I've seen a TF727 in a 75 CJ5
Just depends on your $$ and for the 727, your fab skills.

Thanks AFRd I am not sure what a SBC's are but I think you are right the 3 speed would be better.

That is some good news, does any one know what car and year to get the th350 from or do you buy an adapter to bolt it to the 258. And also what adapter do you buy for the transfer case.

Yes it will require an adapter for both the engine and transfer case.

There's probably not a question you could ask on this subject that hasn't been asked and answered somewhere on the web. Google is your friend.

Before you get too excited, I noticed you have a 6" lift. Be forewarned, your auto swap needs to be very thought out, as the combination of short rear driveline and the angle to the rear is gonna be a dicey situation. I would double check all your measurements and double think all your lengths and angles before pulling the trigger on this.

Agreed. Mine does not have much lift. You can lower the crossmember 1" or so to make it more livable, but definitely want to check all that out.

Thanks jeepdady you are definitely right the 6" lift is a deal breaker and I need to update my information and will right now. We lowered the jeep about a week ago buy doing a spring over we didn't like the jeep that high. And when I realized we couldn't even put a 4 speed in it because of the lift we lowered it. Costly mistake.

It can be done as others have said but nothing just drops in. I believe the shortest factory auto/T-case combo would be the TF999/Dana300 from a 80 CJ7/8. Bonus is that you get the lowest 1st gear of ant 3spd auto and a 2.62 low in the 300.

The shortest factory V8/auto/T-case would be the early Bronco 289 or 302/C4/Dana20. You would have to go to a drivers side diff in the front for this swap.

The SBC(Small Block Chevy) can be adapted to ether of these tranys.

I ran the 302/C4/20 setup in my 84" wheelbase flatty. I ended up with a 14" rear drive shaft but also ran a Currie HP in the rear.

Yep, I believe my driveshaft when running a small block chevy, th350, D300 was 13"-13.5". Very short driveshaft, but I never had any issues with it.

Rattyflatty is onto something. The high pinion Currie diff will solve a lot of headaches with driveshaft angles.
