Auto in a CJ-5

I have access to a 350 and a TH-400 trans. I know they put TH-400s' in CJ-7s is it to long to use in a CJ-5 without running into alot of problems?

Re: Auto in a CJ-5

I think it will be too long and you will have a really short rear drive shaft. Look for a 999,727 or a 904 and you might have better luck.

My girlfriend said if I spent one more dime on my Jeep she would leave. Man I'm going to miss her!

Re: Auto in a CJ-5

I just ran down stairs and measured the rear drive shaft on my CJ7 with Q-trac and it is 19" long at full extension.So I think a 7" to 9" drive shaft might be to short.

Re: Auto in a CJ-5

I remember an article in 4WD & Sport Utility a few years back where they converted a CJ5 from manual to auto. I can have a look for you and scan the article if you wish. Let me know.

The 350/th400 might be a little long. A V6/th350 might be a better idea. If you mount the motor as far forward a possible you could get a rear shaft of ~14". Not real long but workable.

Re: Auto in a CJ-5

I have just swapped in a 454 chevy along with a TH350/Dana300 combo in my's long, and you wanna use an electrical fan, due to length. But it's real nice to have an auto, so go for it

The 727 between my 258 and Dana 300 is 23" long, from front face of bellhousing to rear face of adapter, if that helps you. Don't forget the front driveshaft clearance problem the 727 will give you though. 999 won't have that problem.

Re: Auto in a CJ-5

Going off Advance Adapters spec SBC is 24 inches
the th350 is 21.5" Th400 24.24
and I'm the the transfer case is either Dana 300 or Dana 20
plus you have the adapter itself.....I've just about finished my 75 cj5 350 th350 and even now I'm having problems with tailshaft length...good luck if you try with the TH400

Re: Auto in a CJ-5

I've got a '70 with a 283 SBC, TH400, 18 T-case,and about 3" lift. The rear driveshaft is short but works perfectly, no vibes. I also have a standard fan and custom radiator.

Re: Auto in a CJ-5

This is an idea i have been toying with too, gotta get rid of the T-150 hehe. Tom Wood's drive shafts makes a shorty cv rear driveshaft, would that make the swap easier?
