Transmission was rebuilt and I have been running it for 4 days now. Well today I was driving home and the trans downshifted to 1st year at 50mph and locked up the rear end, then popped some codes and felt like it was slipping real bad. Got codes P0700 and P0776. Now when I got the transmission I had my local shop swap over my old tcm to the new trans so I didn’t have to get a mdi to flash it. A guy I respect in the trans world of building / tuning said it sounds like bad tcm/tcm filters. What are your thoughts?

NEW!!!
I will make one calibration change for an additional $100 per change. For example, changing a shift point for a given gear is $100 vs changing a shift point and a pressure setting would be $200. That value can be used towards the full custom tuning price.
