1994 XR7 Electronic Transmission Prob

For 2 years my 1994 XR7 V/8 has been jumping out of OD momentarily and revving in neutral. I know this problem has been reported but I've seen no solution. I have done a search on this forum.
The oil has been changed twice with the proper fluid. The only thing that makes it happen less often is shutting the car off for 10 minutes and then driving. Makes it hard to diagnose at a shop when this happens.
The vehicle only has 50k on it and sits for long periods of time. The last guy that looked at it said that the seals were dry and he'd rebuild
the whole transmission, not a great answer.
Does anyone, or has anyone EVER fixed this problem? I'm totally lost! I've heard range sensor, accumulator and Vacuum Sensor. Nobody seems to have ever fixed one though.
Can ayone help an old man out

Yeah, I had somebody tell me something similar years ago.

Be glad to try. Sounds for all the world like the Manual Lever Position Sensor (MLPS).
'Tis an electro-mechanical switch mounted on the side of 4r70w and AODE Ford trannies. There was evidently a defective seal in the originals allowing dirt/crud to make it malfunction.
I found a (I think) Wells replacement for the one in my '94 Tbird LX V8 at AutoZone years ago ($25). No fun to install but much preferable to a rebuild.
Might be a little trickier at a Ford dealer: mine wanted to use a '95 part with a different connector. I think they wanted something like $260 to fix it.
More details if you need them.
Cheers, Puddin'
