if you want it to last take a look at the patc site.it's gonna cost you the same probably either way,you might as well have a good build when your done. I'm in the same boat and it took me 4 trans over 3 trucks to figure out these shops are gonna screw you if you don't have some idea of what you need done vs it simply driving out of there shop on the cheapest/weakest components they can profit from!!!!!!!!

 

with everything going on with my truck, would dropping the pan and changing filter and fluid be worth a shot or is that just a waste of time and money?
