6L80E Rebuild kit includes the following:
The 6L Platform
The 6L80 transmission was manufactured in Ypsilanti, Michigan, at the Willow Run Transmission facility. The 6L80 was a much different transmission than its predecessor and was intended to be replaced in 2006 when it was initially released. This new unit came with a new 32-bit controller integrated into the valve body that stayed in constant communication with the ECM via GM's new high-speed can bus network.
This new design approach in the 6L80 utilizes three-way, variable-bleed solenoids to improve shift quality and consistency which are constantly monitored and corrected by utilizing GM's new adaptive shift strategies. The deep first and second gear ratios of 4.02 and 2.36 offer ample torque multiplication with a nice, tight shift recovery. The 6L80 transmission comes with a factory rating of 440 ft. lbs of torque.
The Cat 0 6L80 Rebuild
The Category 0 SunCoast 6L80 rebuild kit has everything you need for a successful rebuild. This kit was designed around a rebuild where on improved clutches and steels are needed. This kit includes high performance Raybestos GPZ clutches manufactured with a unique blend of fibers for ultimate stress and high temperature durability. This SunCoast 6L80 rebuild kit also includes the 3-5 reverse Z Pak and the 4-5-6 Z Pak to provide the ultimate solution to common 6L80 failure points. These new Z Paks are a completely redesigned single sided clutch system that outperforms the OE in torque and heat capacity without coning or deflection occurring.
