104740-09K 6L80E / 6L90E, Compensator Feed Regulator Valve.
#104740-09K GM 6L45, 6L50, 6L80, 6L90 units incorporate a compensator feed regulator valve to assist the clutch return spring. Regulated compensator pressure is routed to the clutch drum to keep the piston in the released position when commanded off, counteracting residual apply fluid. Installing the Sonnax compensator feed regulator valve kit 104740-09K, with improved materials and valve support, will extend the service life of these units beyond that of the OE casting.
