Truck is stuck in 1st, seems like if I try to shift manually it feels the same as 1st in all 3 gears and in D it hums away at 4500 rpm at 50 mph. Took me half a tank to get home from Sussex.
I'm wondering if it has something to do with my recent un-installation of the Interceptor gauge, but I have no clue. No lights either. Any ideas?
