TRANSMISSION IS SHIFTING ROUGH IN FIRST GEAR AND SECOND GEAR

2000 GMC Other • 115,000 miles

After driving for approximately 30 minutes the car begins to shift roughly at 10 miles per hour and again at 20 miles per hour. I recently had the transmission serviced and the filter changed.

Do you have a check engine light and when was last tune-up? Badly needed tune-up will affect the transmission operations-Could be a shifting solenoid sticking, valve body and governor and throttle pressure problems
