For those that have followed the VIN/build date thread my MM is, so far, the earliest one. VIN 600045. I purchaced the car from my dad, fellow board member CMALO. The car currently has 82000 miles on it and around 75000 I began to experience lock-up issues. It started locking up in 2nd and wouldn't unlock until downshift or full throttle. Thankfully, the old man had purchased an extended warranty and it has been to the dealer eight times now for this.
The dealer initially went into the trans and found OD was cooked and replaced components as needed. A complete rebuild was not done even though fragments of OD were found in the fluid. Since then the LU solenoid and a check ball have been replaced. The problem persisted. Eventually, the lock-up pin was removed from the tranny and it simply never locked up, so it was decided that the PCM was bad and the PCM was replaced. No dice. This thing is driving me freakin' nuts! I'm running Lidio's 93 octane tune so it should only lock up above 63 in OD. I want to make it clear that I believe this has nothing to do with Lid's tune since it does it with the stock tune/new PCM. Funny thing is, with the stock tune it acts up very consistently. With Lid's tune it is very sporadic and acts up only after driving for a while (25-30 mi). It will suddenly just be locked in 2nd. If I start in 2nd it will lock about 25 mph and it won't unlock until just before full throttle. The other day it stayed locked down to 15 mph and wouldn't unlock on acceleration. Also won't unlock from 3rd or OD.
I've checked through several threads and seen similar issues. Granted these things are programmed goofy, but considering it does this with or without the tune and that it never did this before 75000 tells me something is amiss. I'm currently being avoided by the Ford district service manager as well as Ford Customer Service, so any suggestions are appreciated. TIA.
