i have a 94 f150 302 e4od. yesterday after making a 4 hour drive from my hunting cmp back home my trasmission was having a problem. it would seem like it would miss a shift and drop into neutral. if i let off the gas and let the rpms drop back down it would shift and work fine. it did this several times. it only seemed to do it when very lightly pressing the accelerator pedal. it had also rained almost the entire 4 hours if that could be a factor. i pulled the codes this morning and all was fine. only got the 111 code for system pass. any ideas?

 

Check your MLPS.

well after looking at this i may have the 4r70w transmission since the plug on my mlps looks like that one. but i do have the overdrive button on the shifter. the mlps readings are within spec but most of them are closer to the upper limits according to the numbers listed here

 

I was thinking about the water and this TSB:
