| No tranny is bulletproof. In stock form, the allison is pretty close to bulletproof. When you start adding power to a tranny it is a tall order. I bet almost all the problems that your tranny shop has seen was on vehicles that had programmers on them running at least 85 hp or more. You got to look at it this way...a LLY has about 310 hp....lbz has 360. You add 100 hp to it and you add nearly 200 lb/ft of torque....something has to give. You wonder why your local tranny shop sees those guys and not the dealer? If it was truely a problem with the tranny, guys would be going to the dealer and not a tranny shop in most cases.
