4L60E Master Solenoid Kit with Harness and Filter 2003-2005

This kit replaces every electrical component on the valve body of a 2003-2005 GM 4L60E or 4L65E (RPO M30 and M32) in one job. In the box: A and B shift solenoids, the 3-2 downshift solenoid, the EPC (pressure control) solenoid, the TCC PWM solenoid, the TCC solenoid, the manifold pressure switch (TFP switch), the internal wiring harness, a transmission filter and a pan gasket.

It crosses to GM part numbers including 24227747, 24227792, 24212690, 24212327, 24209121, 24215111, 24219581, 24230298, 10478120, 10478112, 10478131, 8683187, 8677314, 8684216, 24220158, 24209276 and 24203101. It is year specific: the 2003-2005 units use a different harness and pressure switch than the 1993-2002 and 2006-up transmissions, so check the year before ordering.

Reach for a full set when you are chasing P0751/P0756 shift solenoid codes, P0741 TCC codes, erratic line pressure from a worn EPC, or a TFP switch that reads the wrong range. Drop the pan, pull the filter, unplug and unbolt the solenoids and harness, and swap them one for one. With the pan off you also get a fresh filter and gasket. After install, clear codes and run a transmission adaptive relearn with a scan tool, or expect harsh or erratic shifts until the TCM relearns.
