What was the new part TA sent you that fixed the creep?
The brake itself has 2 parts.. the guy that use
to do my trans work had the same issue so after
checking we found that a crack had developed in
a wall of the brake(after contacting TA he sent
2 this was a error on the build.. that wall would
flex back and forth and finally cracked.. if I
recall right that part was $35...after installing
both brakes were great.. the fix was to put a radius
in on that wall).. its still running great today
EDIT
One thing I like about the TA brake is that I dont
use a button to get into reverse.. just shift to
reverse
