PG transbrake full tree or pro tree
I have a powerglide transbrake and I am trying to figure out if it is a pro tree brake or not. It has a spring on the valve. Is there a way to tell by looking inside the valve body? I am trying to determine if I need to drill 1 or 2 passages in the rear of the case. Thanks for any help.
