I have a 2004 LB7, 1000pk trans, 184k miles. What is the recommended rebuild kit? What comes in a rebuild Kit? What is the cost. Looking to go back with medium duty. No racing or pulling sleds, just a large right foot and RV trailer. Running a Hypertech +90 hp, banks exhaust system, P285,70 16 tires. Nube with alot of dumb questions.
