That would be an AMC TH400 yes it has the guts of the GM TH400 but you will never get a GM TH400 to bolt up to and AMC with out an adapter.
Quote from imacarfan2 on 02/15/12 at 11:57:04:Yep, what Norm (390spirit) said. Just make sure any of these transmissions have the AMC bolt pattern. For example, the 727 comes in the AMC bolt pattern as well as big block AND small block Mopar bolt patterns. They're all different. Also, torque converters for AMCs are different from Mopar converters. Mopar converters have the ring gear connected right to the converter. AMCs don't.
A TH400 from a Quadra-Trac equipped fullsize Jeep is also a decent choice because it accepts any GM TH350 or TH400 torque converter. These are usually cheaper than ones for a Torqueflight (Torque Command in AMC speak). Thing is, you have to have the TH400 converted from 4WD to 2WD using parts from a 2WD TH-trans, so that might be an issue.
For a mostly street driven 401, I'd go with a 727. Give it a good rebuild and you can beat the snot out of it without much complaint. Just don't forget to add a good trans cooler.
Dont forget with the TH400 you will need to machine the case for the speedo too.
