I have a 1998 750C Series II, s/n TO750CX840403 bulldozer. I installed a remaned TCM last October. We used it around 40 hours, and parked it for the winter. About 4 weeks ago it was put back in service. Everything worked well for 20 hours. Then it wouldn't move. Shut it off move the joystick, move the speed control, the it might move 50 feet, stopped, and the message "Shift to neutral" comes on the diagnostic screen. Sometimes it will move, most times it won't. FNR sensor was replaced years ago bit had no use because at that time the TCM needed replaced.
To sum it up the dozer moves sporadically, the tech isn't sure what's wrong, and I need help.
