Chevman, that's not true with our cars. We change 2/3 of the fluid in a pan drop. These trannies hold around 12 total, and 8 flow out with a simple pan drop. It's not like the old Turbo 350s that only lose 4 quarts with a filter change.
Shift kits extend clutch pack life, they short driveline components: axles, input/output shaft, etc. I think anyone with a stock L67 to L36 would benefit. It's when you start working on modded cars and a stock tranny that you'll break things.
The question is, which kit? I know how the spacers work by suddenly stopping the accumulators movement and engaging the gear. But what are we missing not using the kits with springs like the TransGo kit?
well, Rook, actually it's more like 75-80% pours out on a pan drop, cause it takes 10 qts to top it off when you do a filter change. (learned that the hard way) I am running 100% Dexron VI in my tranny now and couldn't be happier. shifts are a little smoother and it isn't near as sluggish when I first put it into drive after sitting when it's cold. I would reccomend switching to VI cause once the III is off the shelves, that's all that will be available (pretty pointless to carry something that won't work in every AT that GM makes since VI is reverse compatable)
