2002 Buick Park Avenue 6 cyl Two Wheel Drive Automatic

my 2002 park avenue starts to hesitate or buck when driving right around 50 miles an hour and 1500 rpms. i took the car out of overdrive and tried the same scenario in 3rd gear. the car ran fine. Open for suggestions.

Problem with lock up torque convertor. Most likely the TCC switch on valve body. a scan tool will be able to determine fault.
