GOLLY! I read thru quite a bit of these threads and the summary from my perspective is....these threads are primarily about drag racing at a drag strip where everyone pushes the limits of pretty much everything...under those circumstances I have seen 50k motors & trans's explode all over the place in vitually every brand of trans and engine. These guys are talking about short shifting at 7000 rpm and such..... NO ONE DOES THAT CRAP on the streets unless they are insane...... I have never shifted any of my street vehicles at 7000 rpm......and if I did I would kinda EXPECT to grenade something eventually..... essentially you can blow pretty much anything to pieces eventually.....for the most part, doing an occasional burnout ON THE STREET the 727 is a pretty bullet proof trans...if you are all talking about serious race cars.... that is a horse of a much different color
