At higher mileages, (125,000-150,000) the automatic transmission may not shift correctly. This can be caused by the throttle position sensor being out of adjustment or a shift solenoid needing to be replaced. Typically the transmission does not need to be completely overhauled.

Doesn't shift from 2nd to 3rd when cold. When engine temp is on the way up to normal, it will shift. A 2 minute warm up usually works. Also shifting onto OD doesn't usually happen until 55 MPH, even when driven for 10 miles or more. Letting off the gas at 50-53 MPH will sometimes allow it to shift but not always.
