NHTSA Complaint #11480907 — 2016 CHEVROLET CAMARO

On Friday August 12th 2022 at 9:30pm check engine light came on after car was sitting turned off for a few hours while my fiance was buffing/polishing/waxing the car. Checked the chevy app, it didn't list any problems. Took it to auto zone. They ran diagnostics. Came back codes P0711 and P0700. Made appointment at AAMCO Monday August 15th. Car was not smoothly down shifting and when put in drive or reverse would jump slightly. AAMCO basically said the transmission was bad. Which I can't understand how that could happen, it's a 2016 only has a little over 70,000 miles on it and is extremely well taken care of. I'm being told we have 2 options either the whole transmission needs to be taken out and rebuilt to find the problem, an estimated $3000-$6000. Or 2 the TCM can be replaced/reprogrammed for over $2500 which is not a guaranteed fix. They also told us a few other chevys with low miles also needed a transmission rebuild! So what is going on Chevrolet!? And we're still making payments on this car and it's already having expensive problems!
