Technical ID this transmission

A friend picked up this factory 1 piece transmission the other day and wondered what it came from? Chevy bell housing with Chrysler torqueflight. Any help would be appreciated. What else is required, special convertor, flex plate crank extension? He also picked a modified torqueflight with C4 Ford bell housing machined to bolt to modified Chrysler case, a 2 piece unit.

 

cool beans, I never saw one of them before! I'm guessing it came in a Jeep behind a 4 cylinder, but that's just a wild guess. If you can find a part number stamped on the flexplate, or find some casting dates or numbers on the case, that would help identify it. Often you can tell what company a part was made by, by the way the part number looks.

 

All the Torqueflights I have ever run across. Have a number stamped on the drivers side of the case at the oil pan rail. Do these?

 

find the pictures on the post they started on, you'll see where it came from

This is fantastic news! Now we know that a A-904 torqueflite was used behind a Chevy engine. Bolt to a 4.3L V6 and stick in anything! I like it! Now if I can find one! (Or two, three)

 

That's bizarrely cool!
After-market converter companies; Pro Torque, Transmission Specialties, PTC, etc, should be able to make a half GM, half Mopar converter. They will just need you to take some measurements, flex plate will be the one appropriate to the engine. I'd use a TH 350 and keep the GM Torqueflite as a conversation piece.

 

Yes, Jeep. But have him check that 2 piece Ford/Chrysler unit- it may be a Clutched automatic. The Clutch Hydro (TH400 with a clutch) and the Clutch Flite (727 with a clutch) are the most common clutched autos, but the fords are out there. They are cool!-rick

 

Great, thanks. I'll get the numbers next time I'm over there. I copied photos from net as I'm laid up with damaged arm and can't download photos from new phone. 2WD jeep, who would of thought that. Had no idea. He'll rebuild it. What a novelty, a Chevy TF727! Did some further research and found from www.jeeptech.com the 151 (2.5L) inline 4 engine was used in '80-'83 CJs including the CJ-8, CJ-7, and CJ-5. The 151 is often called the "Iron Duke", but is actually a Pontiac engine designed to replace the Chevy "Iron Duke" I4 engine.

 

It's a 904, not a 727. Same thing but lighter duty.

 

Those transmissions are very hard to find now but can be built up to handle a pretty healthy motor. Convertor is no big deal either... it is an AMC convertor for a TF-6, they used a regular flex plate like shown and no ring gear on the convertor.

 

Thanks so much, appreciated

 

These transmissions were found in the 2wd US Postal Service jeeps more commonly than in the "civilian" jeeps.

 

I am never surprised at what is on this site,, 904 to Iron Duke,, who'd a thought it.

 

I am not completely clear regarding the year AM General was formed, but I think it is highly possible that is the "correct" brand name for the postal "Jeeps" in which this trans was installed. AM General built a wide variety of military and government service vehicles.

I do think it is cool as Hell to see this......not only have I never seen one before, I had no idea such a hybrid trans existed.

Auction last year had AM General Jeeps from the 1970s. Right off Fort Drum, in fact he'd parted some out and wasn't supposed to, before crushing the shells. I bought a lot of steering columns thinking they'd be good universal hot rod columns, but no such luck.
