Thanks, more research today I and I see they do not use the laminate discs in the Gen2 of the transmission. At this point I'm going to take the risk and replace the TCM. I got quotes today to buy the car as is, and they came back at 2900 to 3300. For 600 dollars I take the chance of getting it drivable and trade in value is $9100.I believe it was 2012 or 2013 when GM went away from the plastic laminate discs.
Why didn't you get an estimate for the repair? If the TEHCM must be replaced, it should be programmed to the vehicle before/during its installation - not something a DIYer can do without special tools and software access. Replacing just a solenoid may cause the transmission to respond a bit differently until the adaptive-driving program catches up to the repair.Anyone else have any ideas on what needs to be done to program it?
