overdrive off problem
I towed my 10K trailer this weekend for the first time in a few months and found I can't get the truck out of overdrive.The overdrive off switch doesn't work and the truck won't shift from overdrive to third under load by itself so when I did the big hills I had to pull it into second.All the wires were pluged in the back of the switch and I checked the fuses,any ideas?? Thanks.

i'm not an expert on the subject but from what i have seen on here overdrive issues seem to be related to the throttle position sensor (TPS) if that is the case, this link is a cheaper fix than a new tps

If you're not shifting in O/D while under load it's most likely that the TPS only needs adjusting. If it's never shifting into O/D, then it could still be your TPS, or perhaps your Vehicle Speed Sensor. If the VSS isn't working you'll have no speedometer as well.
