Consumer Description

I was driving at 60mph when the transmission automatically downshifted to second gear while all sport modes were OFF and T/C was ON. Car was simply on drive, and after merging onto freeway and had completely let go of the accelerator pedal the car downshifted by itself no down shifting was done by the paddles. This is the 4th time my car does this and I have to upshift as fast as possible because RPMs go up as high at 7000. i’ve made some reading and looked at some TSBs looks like this issue has happened to other owners who their vehicle is equipped with the 6R80 transmission.
