I'm helping a friend out that just made a long move to Nevada and his trans shit on the way, It's a stock 2002 GMC Sierra 5.3L with about 113,000 miles. We pulled it out and found a stripped sun gear shell wich is common I guess, everything else looks really good except the seal for the output shaft to the input drum I'm assuming it was for the lube circuit probably starved the back a little.
He's short on funds, no tranny experience, so my labor is free, and I've done a few a long time ago. He just wants to go back to stock with it since it's a stock truck, so just looking to replace all the bushings, timkens, clutches/steels, band, maybe sprags but they look good, bonded pistons look good but it looks like they come in most kits. Pump looks great, stator support looks good. Gonna put a new converter in.
The question I have, there is a few kits that fix common issues in the valve body and pump, shift kits ect....Wich ones are a must do? Wich hard parts are a must replace? Any advice is appreciated since I don't do this very often.
I had to do my own 4L60E on a 97 truck that shit because the converter would rapidly apply/release at highway speeds and smoked the convertor and everything else in the trans. I remember a upgraded valve or kit came out to fix this issue after I did my trans but the truck was already gone. (Still had the apply/release issue) But like I said don't want to miss any common issue's like I did on that one.
Thanks
