I told the trans builder my story, to which he replied " most of them let go on sudden decel" I can't give you a HP #, but I can tell you driving style can help or hurt. My 2¢ merry Christmas!

Do high line pressures play a role?

My condition is fully BLOWN!!

Pro Trans was out so I ended up getting a set from TCS and had them fitted to my pump case. Knock on wood things have been holding up. It's been in my mind that changing to a clean N trans brake might have played a role in this.
