Hi Crosley. Thanks for your input. I talked to a tranny shop yesterday and found one to do a scan. I do not know i fthey have the capability to do the type of scan you speak of though. Is this a tool capability that they all have?
I test drove the truck again yesterday and discovered something new about this issue. I had driven the truck for about 5 minutes or so when the truck started doint the same thain again. Not downshifting or upshifting and just stuck in second. I stoped to find something that was rolling around in the back and making a racket. I turned the truck off and about a nimute or less later cranked it back up and the truck was running properly again. No longer stuck in second. Could the computer have reset itself or something? That still does not tell me why it starts sticking in second gear in the first place though.
