Driving in 3rd
guess my hptuners was wrong then. unless it was susposed to shift into OD @ 255mph 
. been a while but i definetly remember the shift tables would not allow that shift. my car is a 2.73 car however so it may be different than a 3.23 car.

i used to drive around in 3 all the time and on the highway OD. but ive noticed my tranny is not quite hitting as hard anymore at 87K,so i just leave itin D might need a service, or hopefully a new built monster 
if you are running and aftermarket 3-4 set like the zpak or 9 friction and you have a larged od servo sonax/superior and a wide band shifting into fourth gear at full throttle will not be a problem though with the trans stock it is and issue and will cause premature 3-4 clutch failure going WOT 4th

It does feel like driving in d or 3 all the time will wear out mt tranny. Still would like to know why a trans am has d 3 2 1 and camaro's have the overdrive symbol then d 2 1. WHY?
They mean the same just different names for the positions

You cannot outshift a properly tuned 4L60E at the track.
As for the other question. I drive my car around town in "D" every single day. I keep it there until around 40-45 mph, this way my stall can go into lock earlier, and I'm not burning up the lock-up clutch from constant lock/unlock in traffic.
I kick it into "OD" when I know that I'll be crusing above 40 mph for a while.
So yes, considering that I've been doing that since Feb on a daily basis without a single problem, shifting your trans as described won't hurt a thing.
Just my $.02 -Allen

damn doubt it.. i get like 8 MPG untuned right now (bigger cam) converter doesnt lock up and its a lose converter (I went from a 3k to a 3.7k) so when its tuned currectly my MPG should jump quiet a bit? *prays*
my driving is 90% city so id be better off driving in 3rd better mileage and save my lock-up clutch

If you are going to drag race, either leave it in OD (that way the overrun clutches will not come on on the 2-3 shift, which robs oil from the 3rd clutch gear apply), or manually shift it 1-2-3. Leaving it in drive around town, and for most purposes is not detrimental. The least amount of transmission wear occurs when the transmission is in 3rd gear (direct), the whole gear train is moving in the same direction, and there is no under/over drive going on. Not all 4L60E's will have this problem, but a quite a few do, but this is a sound reason to "leave it in overdrive" when drag racing.

At this point, I feel more comfortable just leaving it in OD for everything. Only thing that worries me about OD is doing a WOT upshift into OD. But with 2.73 gears I really don't need to worry about that happening too often.
As for WOT downshifting (flooring from a roll) and drag racing, I'm sticking with OD.
