Simple honest truth, had engine serviced, remanufactured, bad knocking heard when picked up, had it towed back to shop, they made a mistake and repaired it but did not cover towing. Next pick up of car and transmission shifted hard, cruise control failed, speedometer bounced and engine lurched when placed in reverse. They refused to address it, claimed it was something else or bad engine/trans mounts. We took it elsewhere and had the mounts replaced, no improvement, then one day while preparing the engine for cleaning I found a disconnected wire harness hidden from view under insulation and behind both exhaust and engine mount, reconnected it and discovered the transmission shifted properly, speedometer did not bounce, engine stopped lurching and the cruise control worked, I was so happy, until the next day when the computer forced the transmission into "limp mode". Then it was time to take it to Ford for diagnostics and learned that disconnecting the transmission destroyed the bands, they educated me that the computer regulates the hydraulic pressure and without input of speed or which gear the transmission was in, the computer was unable to control the pressure applied and gave it full pressure all the time resulting in hard shifts and useless accessories. Unable to afford another costly repair, I drove it until it broke a band and does not shift out of first gear anymore. Had Power Exchange/Precision Machine Service stopped treating me like an idiot and listened for a minute, took a second look or had known about electronic shift transmissions this would not have happened. I will keep posting this and it will get deleted again, but I will never stop telling people about my experience and exactly what and how I learned about it.
