2001 F350 transmission electrical/lockup problem?
I have a 2001 F350 with 90000 miles. The transmission is having intermittent issues with locking up. When it's working normally it will run around 2200RPM at 70 mph and when I let off the accelerator the rpm's will drop slowly as the truck slows down. When it acts up it shifts through the gears but will be running 3000RPM at 55 mph and if I let off the accelerator the rpm's will drop back to idle. The way I get it to shift correctly is to pull over and shut the truck off then start it back up and it will shift fine. It will continue to shift fine no matter how far I drive as long as I don't shut the truck off. It is completely intermittent and does not have this problem everytime I drive it. The truck is stock with the exception of an AFE intake and an MBRP 4" turbo back exhaust. Transmission has been serviced at regular intervals. Any info would be greatly appreciated.
