4L60E Master Solenoid Kit with Harness, Filter and Gasket

On a 1993-2002 4L60E, shift codes like P0751, P0756, P0748 and P1870-style slip complaints usually trace back to the valve body electrics: a sticking shift solenoid, a tired EPC solenoid, a leaking TCC or PWM lockup solenoid, or a cracked internal harness connector. Chasing them one part at a time means dropping the pan over and over. This kit puts the whole electrical side in one box so it gets done once.

Included: A (1-2) and B (2-3) shift solenoids, 3-2 downshift solenoid, EPC pressure control solenoid, PWM solenoid, TCC solenoid, the manifold pressure switch (TFP), the internal wiring harness, a transmission filter, and a pan gasket. It cross-references GM 24230298 (shift solenoids), 24227747 and 24227792 (TCC/PWM), 24215111 (3-2), 8683187, 8677314, 24208576 and related numbers.

On the bench: drain and drop the pan, pull the old filter, unplug the harness at the case connector and each solenoid, then remove the solenoid retaining clips and bolts. Install the new solenoids with their O-rings lightly lubed with ATF, route the new harness, torque the pressure switch and valve body bolts to spec, then fit the new filter and gasket and refill. Clear codes and run a relearn drive after the job.

Fits GM 4L60E and 4L65E (M30, M32) 1993-2002. Confirm your year and connector style before ordering, since 2003-up units use a different harness and pressure switch.
