Ok so i have a 2004 durango 4.7 2wd with 187000 upon my first long trip (under100 miles) it started to rain well it killed my TPS so i waited the TPD dried out and ran fine got home went to autozone bought a new one with life time warranty replaced it. not a month later it went into limp mode so i pulled the code it was the tps. now this is where it gets strange after that truck ran good for a while the out of no where it popped a tranny code PO760 but had no problem shifting so i reset the computer and bam no cade and ran fine. so now i have got the code at least once a month and i just reset the computer and good to go. so now when it hits this code it will go into limp mode (2nd) until i reset it. I need to know if this is infact a soleniod pack or if it could be a sensor > also the other day after i had to reset it i got in it and started it up and all the dash light stayed on the PRND were highlighted and it would not shift into any gear and no throttle responce at all but when i got out and reset the computer it all worked fine i am at a loss??? ( reset computer i took neg of battery for fivee minutes

 

IMO it is a mistake to buy TPS or MAP sensors from autozone. I've come to experience over the years with different vehicles that using autozone sensors means using the lifetime warranty AT LEAST once a year.

As to other issues I think I would start by checking the wiring connectors on tranny and PCM / ECMs to make sure they are seated properly and in good condition. Also, have your battery tested.
