i have done everything to reset the apps on my truck the only thing i havent done yet is check the volts on the module to see if it matches the volts on the apps plug end i dnt have a volt meter before i spend the money on a dodge part that will cost out the i want to test it. and also i found a site that just sales the sensor can i buy just the sensor or do i need the whole set up. if there is anyone in the dallas area that wouldnt mind helping someone out i sure would appreciate it my truck is an 01 2500 24valve
its just weird ill mess with it and it will drive fine but as soon as i try to mash on it. thats when it starts to downshift act up

 

Moved to the correct forum board.

 

Do a search on here for "Timbo APPS". That will give you all the info you are looking for.

I just installed one of Timbo APPS on my 99. Very easy install with straight forward instructions at a fraction of what Dodge wanted. check engine light is now out and is running great!
