Burnout technique A999 trans

I can only tell you from my experience what I do....no argument...

Out side of the damage sprag from breaking a ring gear....I have never had any sprag problems.....and they are all stock sprags....

Forgot...we twisted to 2 rear yokes of the stock driveshafts...I changed out the rollers and springs....a 5 dollar part.

Do what you want....
