I have 2009 silverado z-71 with a 5.3. I downloaded the new update for the trinity and it has not worked since. I put my truck back to stock updated and now when I try to reprogram it will not work. It will not do the original backup. Says a PCM error. My number on trinity is 6JUS917.

Try this mine was having the same problem.

That worked thank you very much!!

No problem just passing it along. I've been fighting it for 3 days.

Thanks Otis!
