4L60E Remanufactured Valve Body with Solenoids and Harness

A remanufactured valve body assembly for the GM 4L60E and 4L65E, delivered with the shift solenoids, TCC solenoid, pressure control solenoid and internal wiring harness already mounted. It bolts up as a unit in place of the original, so you are not rebuilding bores or swapping solenoids one at a time on a worn casting.

Listed fitment is 1996-2006 rear-wheel-drive and 4x4 GM applications with the 4L60E or 4L65E: Silverado and Sierra, Tahoe and Yukon, Suburban, Express and Savana vans, Blazer and Jimmy, TrailBlazer and Envoy, plus RWD Pontiac and Buick. Confirm your transmission tag and pan style before ordering.

This is the fix when bore wear in the original valve body is behind the problem: P1870 TCC slip, converter shudder, harsh or late 1-2 and 3-4 shifts, 3-4 flare, or a unit that keeps losing line pressure after solenoids have already been replaced. Drop the pan, remove the filter, unplug the case connector, pull the valve body bolts and lower it out with the separator plate, then install the new unit with new gaskets and a new filter.

Torque the valve body bolts in sequence to spec, refill with Dexron VI, and perform an adaptive shift relearn with a scan tool afterward. Skipping the relearn is the most common reason a fresh valve body still shifts harsh on the first drive.
