Exact same issue....replaced all speed sensors, shift sensors, tcc sensor, throttle position sensor, had the trans flushed and new filters with no improvement. Some times it will go 150 miles of interstate driving in OD and then drop out all of a sudden, especially when I have to hit the brake and then resume cruise control. My local dealer just wants to put a transmission in it but I have taken this truck from Maine to Florida and back with no issue (except the OD shift which we are discussing. If it is as simple as a brake light switch I will be happy and yet angry at the same time for wasting all my time and money. |
