Hello all i have a quick ? im not sure i am calling it the right name the "TPI" sensor. is this a part i can buy new at a parts store or does something like that have to come from the dealer?
i am having issues with my truck shifting. thank you in advance for the input.

 

TPS maybe? What kind of shifting problems?

 

shifts up and down while going down the road at a steady speed and it is intermittent.

 

Yeah, sounds like it could be a TPS issue. There are a couple of options as far as purchasing the sensor. Around $150 IIRC. You could try cleaning and adjust it, instructions are here about half way down the page:

Or, you could get a TPS delete kit, which I did. They make kits, or you can build one yourself with a linear taper potentiometer. Here's where I got mine from:

1st/2nd Generation Dodge TPS Delete Kit *91.5-98 12v* [DNR] - $42.00 : Zen Cart!, The Art of E-commerce

 

so the tps delete kit you mention, is it a pain to install and has it worked out pretty well for you? and for anyone who comes across this thread what are your thoughts?

 

It was really easy to install. I drilled a hole in the trim around the instrument cluster, ran the wires through the firewall. The wires come with pins on the end, but not a connector, so you just insert the pins in the ecu side of the harness matching up the colors indicated in the instructions and just heat shrink it. I've been running it for about a year now and haven't had a single issue with it.
