I have a 2000 Pontiac Grand Prix 111,710 miles 3.1 liter engine, and 4T65E Transmission. The car emits a loud whining sound and shifts HARD after moderate to hard acceleration and after cornering. I shut the engine off for approximately 1-2 minutes and it acts fine until the next corner. It then resumes the action stated above again. It sometimes will do this during normal driving. What could be causing this? A sensor or something to do with the transmission? Any help would be appreciated.
have the same problem?
