Default Cadillac 6-speed

The EXT already eated the tranny, since i doubt there will be a built 6 speed in the market yet, is it possible to retrofit a 4l80e?

Harness modification or anything needed can be done, the 6 speed lasted 10 full passes.


Please give me any info...

6l80 e transmission has a built in TCM. theoretically you could grabe a TCM out of a pickup truck and wire it in by I am not sure if its going to send the correct can bus messgaes to work correctly.
