1994 4L80E Question

Ok. That makes since. I assume the transmission in the 94's were controlled by the ecm and not a separate tcm like they are in later years.

Thanks

That's correct. The 94 controller is actually a PCM not an ECM. It controls the power train, not just the engine. There are several standalone TCMs for the 80e on the market. TCI, GMPP and quite a few others.

If I remember correctly sloppy mechanics also had a write up for using an 0411 PCM as a stand alone transmission controller, not sure if that would be helpful in this case or not.

Thanks for the info!
