Sealing Rings

To prevent any significant leakages, 4L65E sealing rings are placed around certain parts to contain the fluid. These rings use a method known as non-positive sealing, meaning there will be a small amount of fluid that is released, though only in order to lubricate the various moving parts found in the transmission unit in order to prevent any grinding together that would create any sort of wear. These rings can be fitted onto various systems of the transmission, including the drum and the accumulator.
