Check the TV cable connection on the throttle body. You can see this better if you remove the air intake tube. If the cable is disconnected DO NOT drive the car anywhere until you reconnect the cable. Damage to the overdrive will result if you keep driving the car. There are replacement bushings made of bronze that replace the original plastic bushing. Do a search here you will find lots of info on this issue......

Would this apply to the 84 as well?

84's I believe use a different type of connection. If the connection is good but the cable has slack, it could be possible that the connection of the cable at the transmission has become disconnected. This is just a guess as I own two 1990's. Maybe someone with an 84 version will chime in....

The early Mark VII's had a TV rod instead of a cable, those with throttle body injection. The rod mounts to the driver's side of the TB, and it has a similar bushing on each end. Those bushings also wear out, mainly they get slop in them way before falling apart. Check both bushings and replace them very soon. it would also help to readjust the TV pressure, it reduces over this long age.

We have a very different setup for our 1994 Lincoln Continental Mark VIIs.

This is a case of taking it to a transmission shop.

Let us know how you proceed.
