I
GM Gen. 2 6T70/75/80 units often suffer shift abnormalities caused by excess wear in the actuator feed accumulator piston bores. This wear allows actuator feed limit fluid loss which prevents proper regulation of oil pressure supplied to control solenoids, resulting in harsh or soft shifts, solenoid codes and clutch failure.
Reconditioning the bore and installing Sonnax oversized actuator feed accumulator piston kit 124740-65K re-establishes correct clearance for revived shift control in all ranges.
