Two questions:

During a burnout, without line locks, some damage is done to the rear brakes in order to hold one's position and smoke 'em up, right?

How much wear is done to the 4R70W transmission when keeping the shifter in 1st until ~5500rpms and popping into 2nd in order to chirp*? Is the 4R70W hearty enough to put up with this occasionally?

*This is N/A, of course, I know the Trilogy packin' crowd can chirp and squeal whenever they want. :)

You engage the OD band every time you manually shift into 2nd.
And when you do it at 5500rpms, it wont be around for long.
