This Level 2 transmission comes with an Mad Dog Reprogramming update kit, Mad Dog shift kit, and Raybestos clutches (replaces factory clutches in the 3-4 drum) the clutch pack also has specialized heat treated steels that can withstand much more abuse, all Raybestos high temp high energy clutches throughout the rest of the unit, all new steels, band, bushings, and rings.
A 500 boost valve, 13 vane pump rotor. We also use 4140 hardened pump rings, TEFLON pump bushing, a 29 element sprag, over-sized hardened sun gear shell (which is three times thicker than factory), hardened input shaft and drum, 4 pinion planetary gear (which has also been cold-freezed to withstand big horsepower and torque), high-temp Pro-series, Kevlar band and a Billet servo ( the Billet servo has 30% more holding power, to give you that full throttle shift without burning up the band. For full competition use only).
However, I highly recommend running a Corvette servo if you’re going to drive the vehicle every day. We discard the oem factory, plastic accumulators and run Sonnax aluminum accumulators to ensure a quality shift every time.
For external full manual box add an additional $395
If a Liftgate is needed at time of delivery a $25 fee will be billed to your credit card. Core Charge is $175.
