Questions and Answers

What's that you say? You want Overdrive in your FSJ? Until now, that was a pipe-dream. But dream NO MORE! We now carry AMC Engine to GM Transmission adapters for FSJ's! Can you say 700-R4? I thought you could......can you also say TH350, TH400 and 4L60E? Great, now it's time to say SEND ME THAT PART! This will also work with the 4L80e (must use the torque converter with the TH350 pattern and, of course the controller).

**Note: works with AMC starters (note that some applications will use a different AMC starter, which will be noted in the instructions).

**Transmission Fitment Notes:

The electronically controlled early 4L60E and the 4L80E will require a separate, stand-alone transmission control unit
The 4L80E can be compatible with this kit, but must use a modified factory 4L80E torque converter that features the TH350 pads / bolt pattern for the provided flexplate (AMC flexplates do not have the diameter required for the large hole / pad pattern native to the factory 4L80E)
The later style 4L60E and 4L80e with the removable bellhousing / hex rear bolt pattern are not compatible for this conversion
The TH350 is the only candidate for 1972-1983 CJ5 Jeeps due to their length, and these Jeeps must not have excessive lifts
Will NOT work with 6L80e applications.
