if you have a true stock syty valve body then don't let that thing out of your sight. Everyone, and I mean EVERYONE who has sent their valve body in to a "shop" has regretted it. Most shops actually soften up the shifts cause if it shifts softer then there is a less likely of a chance of breaking and using their crappy warranty. Do a freakin' search and read about all the people who get rapped by shops. Just have a good tranny built by someone on the boards who understands these trucks and call it good. will save you headache in the end, gauranteed.
