allright i'm getting my th350 rebuilt for 250 plus parts. How much should i expect to pay. I want alittle more beefy gears and so forth but he'll only warantee GM direct parts. So i guess i have to give alittle BUt does anyone know how much those rebuild kits cost?

 

Gears don't come in a rebuild kit.

GM kits are designed to produce granny's grocery cart shifts. They are the direct opposite of a performance build. "GM smoothies" are the exactly wrong thing for what any of us here on this board are trying to make a transmission do.

Get somebody else to build your transmission. Sounds like this guy is a dealer tech, and that's all he knows, is what goes on in new car dealerships. Specifically, get somebody that knows how to build racing ones; whatever you do, don't get it done by the low bidder, and don't use GM clutches in a performance transmission.

 

ya your right he is but he does good work and he's about 400 bucks cheaper than local shops. Can a shift kit help it any or is it still going to be a wuss

 

Actually, alot of builders (primarily 700R-4/4L60-E) are using GM parts because of there place in the performance transmission. Borg Warner "Hi Energy" Bands and clutches come stock in 1998 and later 4L60-E and will back service to the very first 700's built in 1982. The infamous "Borg Warner 29 element sprag" that just about every tranny site has listed, is OEM replacement starting in 1997. GM was a little late in the game when it came time to "beef up" the Reaction Sun Shell, but they finally steped up to the plate and offered something decent, which utilzes a thrust bearing instead of a washer and is now coming from the factory heat treated. Many builders like to mention the fact that they use Teflon coated front pump bushings, well GM has been using them since '96.
Some things that TransGo uses like the servo cushion spring to reduce a 3-2 downshift clunk when using a Vette servo, has been in the Vettes since '91.
And don't forget about the infamous "L35" converter. Thats the converter that came stock in V6 "grocery getter" SUV's and pickups
Yes, I'm a dealer tech and I use Genuine GM parts as much as I can. When GM doesn't offer what I need, then I go aftermarket

 

allright this is my weekend fair weather beater on speed i'm only running about 240 hp although my goal is 300+ but that ain't for awhile will a GM stock rebuild TH350 take it? It isn't my dailer driver or anything but i am kinda rough on it but who isn;t when you don;t have to depend on it the next day.
