Having problems with your 1988 Mercury Grand Marquis ?
Transmission wont go into 3rd or overdrive but shifts fine from first to second
Sounds like the direct clutch is bad. But first make sure the transmission control cable is still attached to the throttle body. If it isn't replace the bushing that holds it on, they tend to break. If it is hooked up the transmission will need rebuilt.
