rolling out the lights?

got my powerglide in and it runs great on footbrake but when i transbrake it will roll out the light what is the most common problem when this happens?

basic cause is that the reverse clutches are being overrun by the low gear. Causes range from not enough clutches, to improper clearance on the clutch pac, to leaking brake piston. Try adjusting the solenoid servo in a quarter turn or so and see if it is any better. I am assuming you are rolling forward when on the gas. If rolling backward when the button is on then try raising your stage rpm.
