First is that I got the truck back from an acquaintance with the overdrive light flashing. He was towing a trailer and I have a suspicion that he ran the truck with the overdrive on through a couple mountain passes.
In reading the posts, it seems that this is a caused by a built in sensor. Is there any way that I can "reset" the light to make sure that it has a problem? Can I get a code reader and diagnose the problem myself? Does anyone else have a suggestion for someone on a very small budget?
Any help is greatly appreciated.
