The Transmission = ATI

I have heard ATI makes a pretty slow transbrake. After talking ato ATI, I have the fastest one they make in the car. Reaction times still aren't where they should be, especially with a car that is designed to race super gas. I should be going red with the delay I have. At Gainesville, .020 delay, reaction times were in the teens most of the weekend. At Indy, had to drop my delay to .000, and still couldn't get any faster than the teens.

I know pro brakes are faster than a regular trans brakes, but what makes them different? I have swapped trans brakes out of an old transmission I had in my old Camaro. Going to see if that helps any.

Any other suggestions?

Make sure the stock Powerglide case reverse fluid passage from the valve body to the reverse piston is 3/8" Dia. all the way.and clear of obstructions, Ray
