My uncle has a Wagoneer with a quadratrac drive train and I am wondering if the auto transmission from this monster: 1. would be feasable in a CJ-5 with a 304 and 2. has a better top gear that a T-150 3 speed? I am building this CJ from the ground up and recently tryed to test fit the engine and trans before having the frame sand-blasted. I have one skid-plate from a '79 with a 258 6cyl and t-150. I have another skid plate from a donor which I don't know alot about. With the three-speed, I cannot find a combination that fits together. I hoped that the auto would be longer so everything would fit.

I read somewhere that the ?727 was a heavy duty trans used from '80 to ??. I am pretty sure that his wagoneer is older that '80. If anyone can tell me how many posibilities ther are I would appreciate it greatly.

As to what the tranny may be I think your other possibility is a TH400, I had a '75 with Quadratrac and it had the 400.

what is the VIN#
this will allow a more informed answer to ur Q...

Autobox before '80 is a TH-400. The 'Quadra-Trac' before '80 is the BW-1339 x-case. These are both HD units. Since 1980 they used the TF-727 autobox and NP-228 or 229 x-case. I'm not sure if either of those was ever called the 'Quadra-Trac' although they were called 'Select-Trac'. Once again, the transmission is very stout, and the 727 should be short enough to use in a CJ-5. A Dana 300 will mate up behind it too so you will still have the front output shaft on the passenger side.

Two very easy ways to tell if your uncle's truck is pre-80 or 80+:
Stand in front of it, are the headlights round (pre-80) or square (80+)?
Look under it at the front axle. Is the differential on the passenger's side (pre-80) or driver's side (80+)

Pre-80 probably is the TH-400 or the TH-350 auto tranny.

I'm big. I'm heavy. I've got true four wheel drive. Therefor, I own the road!

I've never heard of a TH350 in a stock Jeep. Has anyone?

the auto tranny from any vehicle is too long to fit in a cj5 that was one of the reasons that amc came out with the cj7 in 1976

A Cj-5 with a V-8 pushed forwards a bit can run an auto tranny and a short x-case. I think it was Petersons that used a 350/350/D-300 (or was it D-20?) in a CJ-5 a while back. I agree that with an I-6 it would never work.

The TF-727 is pretty damn short, and the '80 D-300 is the short-shaft model, about 1" shorter than the later models. With an AMC 304/360/401 it might just be possible provided the lift isn't over 4" or so.

Hell, there is a CJ-3b on the BC4x4 'site with two transmissions in it. Where there is a will there is a way!

OK, time to get cheap!! Go to the junkyard, and find a Jeep with ROUND headlights and a 4 speed. (Cherokee, Cj, J-series pickup, doesn't matter.) It should be a Warner T-18 4-speed manual transmission. This transmission was used alot behind the '74-'79 V-8s. Shouldn't be more than a couple hundred $$ AT THE MOST. It'll should bolt right in, and you won't have to worry about buying a new, shorter driveshaft.
