4L60E Remanufactured Master Solenoid Kit with Pressure Switch

A master solenoid kit for the GM 4L60E family (4L60E, 4L65E, 4L70E). As pictured it contains the EPC pressure control solenoid, the TCC PWM solenoid, the 3-2 downshift solenoid, the A and B (1-2 and 2-3) shift solenoids and the pressure switch manifold (TFP switch). These are remanufactured units; each is checked before it ships, and there may be light surface wear that does not affect function.

The 4L60E went through connector and solenoid changes over its production run, so compare the connector colors and shapes in the photos against what is on your valve body, and confirm year, engine and OE part number before ordering. The kit is listed for GM trucks, SUVs and vans from the mid 1990s through 2012, including Blazer, Astro, Safari, Trailblazer, Colorado and Canyon applications.

Replacing all five solenoids and the pressure switch at once is the standard fix when a 4L60E throws more than one electrical code, loses 1-2 or 2-3 shifts, goes into limp mode, or shows erratic line pressure. Pull the pan and filter, remove each solenoid retainer and the manifold bolts, install the new parts with clean ATF on the O-rings, torque the manifold bolts evenly and run a relearn after the refill.
