6L80 Level 3, 4-5-6 CLUTCH KIT:
7 G3® Clutches
9 Lindered Steels (varying thicknesses)
1 Stepped Apply Plate
1 Wide Backing Plate
1 Snap Ring
2 Hi-Per Blue® Bonded Pistons
CDT456L3/80-P offers 50% more clutch apply area than stock. G3® friction material is formulated to achieve minimal wear and maximize heat resistance. Lindered is a chemical and heat treatment process that hardens the steel, which results in less wear. Hi-Per Blue® Pistons are manufactured with upgraded High Performance Blue AEM material for superior thermal and chemical resistance, with better fit and performance. CDT's Billet 4-5-6 clutch hub and intermediate shaft (CDT part number 104680-45-P) is required in order to use this clutch pack.
Upgraded Parts If you have an early pump cover (stator) that does not utilize anti-rotational tabs on the sealing rings or an early 1-2-3-4/3-5-R clutch housing that does not have the matrix stamp you will need to install a factory upgraded pump cover and clutch housing.
Transmission Tuning Please understand that proper tuning of the TCM and ECM are mandatory. All 6L80/90’s are torque base shifted units. The torque signal is calculated thru the ECM. Therefore, transmission performance & longevity are directly dependent on the delivered torque signal that’s calculated in the ECM. If this is not done properly, you will experience premature transmission failure. We also do not recommend maxing out pressures or deleting torque management completely because it will cause seal failure and/or hard part breakage.
Flushing Cooler & Lines We cannot stress enough the importance of flushing the transmission cooler(s) and lines, even if they are new. We recommend using a Hot Flush Machine Flush Machine or something comparable.
Auxiliary Cooler You need to install a stacked plate auxiliary transmission cooler (not a tube & fin style cooler) rated for 25,000 GVW. The ideal operating temperature for this transmission is 180°or less. These transmissions have a tendency to run very hot – the cooler will lower operating temperature and recovery time which in turn will extend the life of your transmission.
