6L80E, Center Support Seal Kit, Sonnax #104740-14K
The rubber seals between the center support in the case and the machined surface of the valve body are prone to leakage over time, in GM the late model 6L## series of transmissions this can range from a 6L45 to a 6L90, this will almost always result in continuous line pressure and lube flow loss as well as clutch leakage in Reverse, 2nd and 6th. Installation of our seal kit will prevent any leakage that occurs due to the gap between the rubber OE seals and the valve body center support.
