Hello Guys, I'm having an issue where the TCC will either stop locking, or never lock. Verified in the scanner that its not receiving the apply signal. I can pull over, cycle power and it will operate normally again. Its a 58X 5.3 motor, 4L60 without ISS run by a E38 ECM with T42 TCM in a 86 C10. Any ideas on what I've missed? I know its not ideal to have an non ISS trans controlled by a T42, but I was able to make it work, and hope its not causing my issue.
