Only the AMC TF has the right bolt pattern for the engine. Chrysler TF has a different bell housing bolt pattern, same with a GM TH400. Since yours is a 71, the crankshaft on the engine won't accept the TF or TH400 converter snout. You'll need to swap to a 72-up crank, have your crank machined, or use a 1/4" thick adapter that's available from American Performance (www.oldcarparts.com). Here's a link to the kit Bulltear sells.

A Jeep TH400 (used from 76-79) will bolt up with the same adapters plus a spacer ring in the crank. The Jeep trans didn't have a speedo connection, so you would need to swap in a GM tail housing and output shaft to get a speedo drive.

For overdrive, you could find a AW4 from a 4.0 powered 2WD Jeep Grand Cherokee from the late 90s, early 2000s. It would require a TCM (which is a stand alone unit) and a TPS to be installed.

There are also adapters available from Novak to adapt a GM 700R4 or 200 4R. Both of these would require some mods to the floor pan since they are so wide.

So, the short answer is there's nothing but a BW trans that will bolt up. Everything else will take some additional work.
