Re: 6.0 Pacbrake PRXB Exhaust Brake
On a 4R100
a brake tune will destroy a trans.......Jonathan from Dynoproven.com brought it up to me once.....His first questions was, "do you have a BTS trans?". He stated it locks up the coast clutch....stock or most modified grenade. 5R110 is basically the same mechanically. Look into it.
