Complete 4L60E valve body with separator plate, solenoids and internal harness for 2003-2005 GM trucks and SUVs. Bolts in through the pan.
Instead of a bare casting, this is a complete 4L60E valve body assembly for 2003-2005 GM trucks and SUVs, built with the separator plate, the shift, TCC, and pressure control solenoids, and the internal wiring harness already mounted. It goes in through the pan as one unit rather than a pile of parts you have to match up yourself.
On a 4L60E, the valve body and its solenoids work as one hydraulic-electrical system: the computer commands the solenoids, the solenoids move oil, and the oil moves through bores that have usually worn right along with the solenoids that are original to the truck. Replacing a worn valve body but reusing tired solenoids, or replacing solenoids onto a worn casting, both leave half the problem in place. Buying the assembly removes that guesswork and gets a matched set installed in one job.
If a solenoid-only repair already failed to clear your codes or symptoms, that is a strong sign the bores inside the casting are worn and feeding the new solenoids bad pressure, which is exactly what this assembly fixes. Our valve body wear and bench fix guide covers how a worn bore undermines even good solenoids, and the shift solenoid symptoms guide is worth reading first if you have not pulled codes yet.
This assembly is built for 2003-2005 4L60E, 4L65E, and 4L70E applications. The internal harness and case connector on 2003-2005 trucks differ from the 1993-2002 layout, so this harness will not plug into an earlier case even though the valve body itself shares the same mounting pattern. Compare the connector on your old unit against the listing photos before ordering, or send your year, vehicle, and VIN and we will confirm it. The bare valve body versions for other years, including 2001-2002 just before this one, are on the 4L60E parts page.
Drain and drop the pan, pull the filter, disconnect the internal harness at the case connector, and remove the valve body bolts while holding the plate against the case so the check balls stay seated. Note each check ball location before the old plate comes off. Set the new assembly with its plate and gaskets, run the bolts in by hand first, then torque in sequence to spec, plug in the harness, and fit a new filter and pan gasket before refilling with Dexron VI. A separator plate is already included here, but keep one on hand as a spare if you are doing this job on more than one truck. Let the computer relearn its shift adapts over the first several drives.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
The valve body, separator plate, shift, TCC and pressure control solenoids, and the internal wiring harness, all assembled and ready to bolt in through the pan.
No. 2003-2005 trucks use a different internal harness and case connector than 1993-2002 units. Match your old connector to the listing photos, or send your year, vehicle and VIN to confirm.
The valve body and solenoids work together hydraulically. Replacing only one side while reusing a worn or tired counterpart usually leaves the original symptom in place.
That pattern usually means worn bores inside the valve body casting were feeding the new solenoids bad pressure. This assembly addresses both at once.
Six months.
No. It relearns shift adapts over the first several drives on its own, though a scan tool can reset adapts immediately if you have one.
