The transmission pressure control solenoid may fail causing erratic shifting. Our technicians tell us that partial dis-assembly of the transmission is necessary to replace a failed pressure control solenoid.

    hard shifting first and second gear only after the car has been running for 20 mins. If I turn the car off for a few mins. The car shifts ok for about 20 mins. Then problem starts again.

    It started around 125000 miles. It only happens when it is cold (usually below freezing). When I shift into reverse to back out of the garage the first time in the morning it really goes into gear with a wham. After that it usually doesn't do it again until next morning. I don't know if it is doing any harm or not. It hasn't been fixed.

    My 2001 Lesabre jerks as it shifts, but it doesn't always happen. If it does it, it continues to do it. But the next time it might work fine. I have learned to let off the gas and let it slowly shift into the next gear. My husband does not do that so when he drives it really chugs into gear. I have no idea other than what I have read about the transmission solenoid being the problem. But I think that it is strange that it does not always do it. I was quoted $640 to replace the shift solenoid.

    The automatic transmission jerks slightly with normal gear transitions; jerks harder when stringly accelerating.
