My 1991 F150 5.0 Lariat 4x4 bucks when outside temperature is warm

Asked by Mar 02, 2017 at 08:25 PM about the 1991 Ford F-150 XLT Lariat 4WD SB

Question type: Maintenance & Repair

During the warmer months here in Virginia, my 1991 F150 surges (feels like someone ran into the back of me) when it shifts gears. During the colder temperatures the vehicle shifts smoothly. (Automatic Transmission). This condition only occurs during the warmer months. Taken it to several places and no one can give me an answer. What's up?

Might be a torque converter clutch solenoid. Try some SeaFoam TransTune and see if it unsticks.
