Trans Problems!

Second time in 35 passes rolled the sprag for second gear on the T350 in the SS car! Ideas why?

I was told not make 1-2 shift in burnout, so I just started burnout in high, and if reverse pattern was told not shift from high back to neutral while moving....
both were hard on sprag..

Yep, we do the 2nd to high burnout but on the other end we do go high to neutral.

Do Burn out in High Gear only. Make sure to use 36 Element Dog Bone Sprag with harded race.

I always thought that was funny, engine builders say don't leave it in gear at the end of a run and trans builders say don't shift to neutral

From what I have been told if you shift to neutral after the run the trans wont oil good enough coasting so fast. I dont know for sure but understand that it is hard on the motor slowing down in gear too...

It is not good to shift a 350 400 into netural at the line it over speeds the drum, sometime causing it to come apart.
