Had transmission replaced at authorized GMC dealership may 2006 . This came with a warranty. Several times over several summers since then have taken vehicle into dealership with concerns that happened after vehicle would be driven in high humidity high temperature days after traveling a minimum of 60 miles mostly on state highways that are quite rough and curvy, I. E. It would take about 90 minutes or more togo this distance. Then when in bumper to bumper traffic and trying to move forward or stopping the car's automatic transmission would cause the vehicle to shake like jumping into the wrong gear and in more than one time the car's engine would die. It always happened at low speeds so luckily we didn't loose control of the vehicle. But, the only way to stop this from continuing was to stop and park to let the engine and or cool down. We even put on the heater while driving to help reduce the temperature gauge to go below the halfway mark. This car was purchased in shelton, wa not in ky, so we never experienced this prior to transmission replacement. The service department has never been able to duplicate problem, now the cruise control has stopped working. We have dashboard warnings continually stating low oil, service engine soon (when just completed), etc. X.
