'94 t-bird 4r70w transmission

[bfjou812]

I've been having some problems with the transmission seemingly going into neutral while driving, what it does is the engine revs as if it was in neutral - if I let off the gas it resumes correct operation. No rhyme or reason to it, can't duplicate it. My question is can a "repaired" ECM be the cause? I had to have it repaired due to a starting problem and it sems all this started when I did this. I changed the fluid and filter, no metal in the pan, actually fairly clean, some sludge. I'm thinking the torque converter or a bad program? If it is the program can Ford reprogram it? 4.6 , 100,000 miles.Thanks for your help.
