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 is mandatory. All 6L80/90’s are torque-based shifted units. The torque signal is calculated through the ECM. Therefore, transmission performance and 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 and fin style cooler) rated for 25,000 GVW. The ideal operating temperature for this transmission is 180°or less. These transmissions tend to run very hot, so the cooler will lower the operating temperature and recovery time, which in turn will extend the life of your transmission.
