Correct - I ran my stock ECM with the programmed TCM and worked great.

Next problem is - my local "stealership" said they won't do a case re-learn on the car since it has a "modified ECM". They told me all they would do is flash it to make it "stock" again. They won't touch it with an aftermarket ECM. My check engine light is on and from what I've been told, the car could just die at any moment. Trying to figure out what to do next........

In the end, I hope this is worth the hassle!
