Update: I left my Vette with the dealer for a week along with a printout of the advice to use that tech 2 diagnostic tool. They said that is what gave them the code for a bad TCM(transmission control module) in the first place. They tested it again and got the same code. So a 2nd new TCM was installed and 120 miles over several trips driven for testing and no repeat of the problem. I have not had a repeat event either. So the analysis was a bad TCM and a bad 1st replacement. Now I’m a happy Corvette driver! Thanks everyone for your input.
Excellent news Ken. Much better news than we were giving you. Always great to see a problem solved quick and easy.
Plus great info you have given here for others.
Glad you’re rolling happily again
