92 4.9 liter 6 , transmission jumps out of gear
I 'm a dissabled vietnam vet with no auto mechanic expierence. My 92 ford F-150 Pickup with the 4.9 liter straight six and auto OD transmission has a shifting problem. I wonder if any one can help me. My problem is than my transmission shifts from OD to 3 and than back again intermittenly. I just had the tranny overhauled about 2 months ago and than this started to happen. Sometimes when traveling at a lower gear it will do the same thing. It feels like the engine is missing. I just had a tune-up but it is still happening. Someone told me that it could be MLP sensor. I had the MLP sensor changed in 1997. Could it have gone bad already? I woul appreiciate any help on this ,
Thanks
Thanks

The MLPS was redesigned due to water intrusion, so it's possible you have the old design. I'd consult whoever rebuilt the transmission about the current symptoms, & pull the codes.

I'd change the MLPS. When they start to fail they cause the problems you are seeing, and won't set a code for a long time. By then the trans is usually ruined by the bad MLPS.
