tranny brake ....need help

When you are foot breaking the car you have vaccum so the secondarys open imedeately upon flooring the car.
If you want to use the trans break get a double pumper.
Light the first bulb,Clear the engine out,put it into 2nd run the rpms up to 1500 roll into the 2nd light,don't deep stage.Pust the trns break button,let the foot break loose.When the lights start to come down floor the throttle let it hit the rev limiter,release the trans button and have fun.
