Transmissions

First, we always recommend direct fit parts because sensors don't always work properly from one year to the next. If the check engine light has come on, have the computer scanned to see if it is a trans codes stored. If no light has come on, make sure the trans fluid is full. To me, it sounds like a bad shift solenoid. However, since it fixes itself when you turn the key off, it could be there is some incompatability between the PCM, trans control module (newer model)and the solenoid.
