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

This is a complete valve body electrical service for the 2003-2005 GM 4L60E and 4L65E. As pictured, it includes the 1-2/2-3 (A and B) shift solenoids, the 3-2 downshift solenoid, the EPC pressure control solenoid, the TCC PWM and lock-up solenoids, the internal wiring harness with case connector, the pressure switch manifold, a pan filter and a cork pan gasket. The solenoids are refurbished units.

Fitment is year-specific. The 2003-2005 harness and connectors are not the same as the 1993-2002 or 2006-2007 versions, even where the solenoid part numbers overlap, so confirm your model year before ordering. It covers OE numbers including 10478112, 10478120, 10478131, 24230298, 24215111, 24219581, 24220158, 24203101, 24209276, 8677314, 8684216 and 24212327.

Use it when you are chasing multiple electrical codes on a 4L60E (P0750-P0758 shift solenoid, P0748 pressure control, P0740 TCC) or when the harness is cracked or melted from heat. Drop the pan, pull the filter, unbolt the pressure switch manifold and solenoids from the valve body, unplug the harness at the case connector and swap everything as one piece. Install the new filter and gasket, refill and perform the adaptive relearn with a scan tool afterward so shift feel does not come back harsh or erratic.
