The transmission overdrive relay often fails, preventing the transmission from shifting into overdrive

    when accelerating, cannot get the car to go over 40mph,and the transmission will not shift. There is an arrow light on, on the dashboard, when turning turbo on, cannot tell if the turbo engine is on, except for the fact it will go to 45mph.

    Transmission won't shift up into high (overdrive?)If I continue driving, at 14 miles it will finally shift. Last summer when it was hot it would begin shifting up right away.

    Same issue with the transmission overdrive. Bought the car 2 years ago from a private party, and it starting acting up about 3 months after I purchased vehicle.
