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?
