I have a 1999 F-150 with the 4.2L V-6. I have been having all kinds of transmission problems and a few others. The truck is shifting at weird times, popping hard out of gear when braking, and the check engine light is on. The transmission shop (just rebuilt the tranny twice)said that they think it is the TPS sensor. They showed me where it is and said it was just a bolt on part with 2 screws.
My question is:
What am I getting into by changing this? Is it easy to do and does it take any adjusting. It looks simple. Also, would a bad TPS cause these symptoms? Thank you so much for your help.
I'll take shot. I only replaced the TPS in my 1986 F150. The repair is easy and cheap, other than getting at the darn thing. I don't know where it is on our V6's.
My truck was a manual. Symptoms were that the truck tried to run so rich that it would buck and die. At first it was intermittent, and then finally I got stranded in the parking lot at work.
Just a thought: I'm not sure I'd believe a transmission shop that had to take two tries to get it right (if that's what happened). Seems like it's in their interest to blame something other than the tranny. Maybe they still don't have it right.
I pulled the codes on my old truck and they told me the TPS was the problem. Don't guess. I don't know if we can easily check our own codes on these new trucks, but at least have a shop with the right diagnostic tool check it out.
