The mechatronics four sealing sleeves and sealing adapter are actually gaskets between the transmission and the valve body. They allow transmission fluid to enter the valve body while maintaining a tight seal. Without this tight seal, transmission fluid can leak out causing a drop in hydraulic pressure.
