Vue Transmission and Computer

Only during the summer, my 2003 Vue transmission jerks and shifts to (I believe) to a higher gear. Mechanic replaced the computer “harness” but it did not solve the problem. The car has little power to accelerate from a stop. I usually pull over, turn off the motor, and restart the vehicle.

please say it is not the CVT trans that is paired with the 4 cyl motor?

Nope! 6 cyl motor on the 2003 Saturn Vue with transmission problem. Someone said there is a electrical surge from the computer. I don’t know. Vue works great in cold weather

Asian af33 trans. Use Toyota fluid. A drain/fill is easy.
