When i come to a stop my truck will not down shift back to first, it will stay in second or third. took it to the dealer, said i had low voltage so i put two new batteries in it. it worked for a while then i hauled a trailer about 4 hours and it started agian. they also said there was something about a low line pressure, or something like that when they did diagnostic. havent had them check anything since then. looking for ideas or thoughts, its an 06 cummins, auto tranny.

 

replaceing the govenor pressure solinoid and pressure sensor (inside the pan) normally cures the problem and with the code of line pressure, i bet that is it

 

awesome, i got those part and swapped them out. im think within the next 500 miles will tell me whether its fixed or not. but if not ill keep posted. thanks for the advice.
