TorqueFlite Burnouts

so, here is a thought

i have an regular auto 727
it is the 1-2 shift that kills the sprag, correct?

why not just shift into 1st, and keep it there during the burn out?

Bolt in sprag anyone??

I was told a bolt in sprag is just one that you put in a transmission that has spun the sprag in it and messed up the case. You can buy a good sprag that has more rollers.
