I am having a problem with my TCC, 4l80e fresh rebuild, 500 miles. All sensors and solenoids were replaced. Everything worked fine for a 100 or so miles then the TCC stop engaging. No codes, I can use my Snap-on scanner and turn it on manually it works fine but will not work on it's own. Have replaced internal wiring and solenoids again, still nothing. Any idea?
have the same problem?
