AMC Automatic Transmission Choices
 
What automatic transmissions are legal to run in AMC's?

Thanks!

Daren, it was kind of a Hodge-Podge depending on year, engine and model.
there was a lot of Chrysler 727 styles used, and even a GM Turbo 400
at one point. If you could narrow it down a little, I can try and be more
helpful.

After Chrysler bought AMC all AMC and Chrysler transmissions are legal in stock and super stock.

All 72 and later cars used Torqueflites. The V8 version of the 904 (998/999) is what most AMC guys run.

This is also like an April Fool's thing for me.

I bought a 68 AMX a few months into the model year from a guy who couldn't afford the payments he thought he could. It had a totally junk Borg Warner automatic that needed rebuilt at 20k miles. The next year they changed to a Torqueflite.

In 67, I bought a Barracuda with the top engine offered - a 273/235. The next year the 340 was introduced.

Yes, I suck at timing.

Borg Warner aluminum M40 series , cast iron M11,12. JeepTH400 ,AMC 904 /72
Pick carefully with the 904 cases ,later cases are weak around the bellhousing area

What Tom said, what Foley wants a Gremlin/Pacer/Hornet in the trailer for those ahem questionable track conditions that a Copo might not enjoy?????
