Shift position sensor on side of tranny where shift cable hooks up sounds bad . Mine would do it at different times . Like pulling a long hill thought it would rip tranny out. I replace with used one I had and been fine since . Hope your is this simple if its not the sensor.
As for the fluid foam don't know it would act up miles from home and just kept driving . Hey if tranny went I wouldn't have to haul as far.

Mlps
Agree with above post. I believe the technical name is MLPS Manual Lever Position Sensor. Went bad on a '94 Bronco with nearly identical symptoms. Pretty cheap to replace. Definitly try that before swapping trans. out. If you do an internet search or look at this website there are plenty of references to this problem. Primary problem is water gets into them and raises he**. Good luck.

Codes can be set without the CEL coming on.
www.fordfuelinjection.com has the procedure for pulling them if you're unfamiliar. You'll have 3-digit codes.

I've got the same problem with my son's 93 f-250. I was going to change the trans filter today and see if it helps. Let me know how you make out with the sensor.

More evidence.

This link partially explains why codes don't get stored with this condition. Don't know we're right but it sure sounds similar. Good luck.

Well I went ahead and picked a mlp sensor up and will try to get it in today. Let you know how it goes. I did change the trans filter and fluid saturday. Really don't know if it helped or not as it doesn't do it all the time. Fluid was fine but the filter and magnet had alot of fine metal all in it. The trans was rebuilt around 50,000 miles ago. So I think it needed to be changed anyways.

Got it in and it seems better. Now you don't have to play with the gear shift to start it. Not that you needed to all the time. Put the key in and it starts right up. Won't know if the rest of my problems are fixed till I drive it some more. Problem was, it didn't do it all the time. Same with the shifter in park, just sometimes. But I did have the same problem as Water 5, about after it warmed up, pull up to a light and try to go it seemed to be in neutral. If you shifted it into low 1, it would take right off. Then put it in Drive and all was fine. I don't drive this truck much so it may take alittle time before I'm sure it's ok.
