03 f-350 transmission searching when computer commands overdrive lockup

i have a 2003 f-350 4x4 with a 7.3 i have re built the transmission i had a done right torque converter put in and a trans go shift kit put in when re built the truck has an edge evoulution obd2 programmer the problem stays the same when the programmer is removed when i get up to about 45-55mph and the computer comands the trans to lock into overdrive the truck will "surge" 500 rpm up and down trying to lock up into overdrive and after trying 5 or 6 times it will stop unless you continue driving the same speed like on the highway or stop shut the truck off and re-start the truck and get back into the 45-55 mph range will it continue i have tested the throttle position sensor the map sensor i have replaced the solenoid pack in the belly pan of the trans and i have also added an aftermarket resistor to the harness that connects to the trans to boost pressure thinking i was loosing pressure somewhere the pressure before when crusing at 55 was 62psi and now after is at 92psi but the problem still continues can anyone help point me into the right direction so i can fix the problem


the truck does not throw any codes and the check engine light does not turn on either and my thinking is pushing me twards electrical due to the inconsistancy of the problem not mechanical

so we are pretty sure that the problem is coming from the pcm we have tested everything we could think of and the brain of the truck is the only thing we cannot rule out i will be putting in another brain and posting results so hopefully your buddy can fix his pickup

My buddies turned out to be a solenoid in the trans, less than 100 bucks. If you need more info let me know, I'll ask him and get details if you want them
