Transmission slips extremely badly even though it doesnt even have 90k miles almost makes it impossible to drive in city and is dangerous when needing to speed up and slow down. Transmission slips more when speeding up from slow speeds and will reach high rpms of 4700 even when not touching the gas but I have had it slip on the highway out of nowhere and it peaked at 7300 rpm when not touching the gas which is past the redline on the rpms. It happens almost every day I drive to work (20 minutes on the freeway) and shouldn't be happening with this low amount of miles.
Automatic transmission slips/jerks/jumps when upshifting and downshifting at low speeds and highway speeds, brought to dealer and had transmission diagnostic conducted, reported no problems and stated they could not duplicate the erratic shifting. Now currently thuds and physically jumps when shifting from 1st to 2nd to 3rd and even 4th to 5th, brought it in again to GMC dealer and they said I would be needing a new transmission at only 110000 miles, advised me to check my car VIN# for valve body recall.
