Worst time to go WOT
just drive the dam thing if you beat on it it will eventually break... but just to add i beat the **** out of my car and i leave it in 4th even though i knoe the 4-2 shift is suppose to be the weaklink in a 4l60e i think so long as you keep things cool your tranny woll probally enjoy a long life....if your really worried id put th selector in 3rd before a race this way you dont have to come out of overdrive on the wot downshift

I just replace mine every couple of months 
I drive a heavy *** truck though.
Ive heard before that the worst thing for the 4l60's is the WOT 4-2 downshift. I dont understand enough to know why, but I know that of the trannys Ive fried since September, most have lost the 3-4 clutch pak. I dont know where the 4-2 downshift comes into play here, or if it does, but if you are making a lot of power and drive the **** out of it it WILL break. Thats when you get a real one built.

like stated earlier..from a stop leave it in OD..from a roll...drop it into D but as you do it press the gas to keep the rpm's up so it doesnt drop hard into the lower gear..

this thread is retarded. we will never know the answer because people arent talking about the same thing in each reply. some are talking 4-2 shift others are talking 4-3 shift. i argued with a local tranny builder about tearing up the tranny from leaving it in OD and he said it doesnt hurt it going 4-3. i then tried to explain to him that it was going4-2 not 4-3 and he said that the tranny doesnt do that and if it did it still wouldnt tear it up. as rough as that shift(4-2) feels i guarantee its hurting something or at least wearing it out faster. heck, i killed my tranny in 10k miles racing about 3-4 cars a month every time from a roll. so in 3 months i killed my tranny but 4-2 has nothing to do with it???? btw, i race from a roll cuz i have no traction from a stop in my pickup. basically, if you think you are tearing something up you probably are so stop doing it or buy a better tranny.
