4L60E Valve Body 2001-2002, remanufactured and ready to install. Fits the 4L60E. Ships fast from the USA.
A 2001 or 2002 Silverado, Sierra, Tahoe, Suburban, or Yukon running the 4L60E that flares on the 1-2 or 2-3 shift, shudders when the torque converter locks up, or throws a P0741 or P0748 code is almost always dealing with a worn valve body rather than a failed clutch pack. This is a remanufactured 4L60E valve body built specifically for 2001-2002 applications, backed by a 1-year warranty and shipped ready to bolt in.
By 2001 the 4L60E had settled into GM's OBD-II-era electronic control strategy, which reads vehicle speed, throttle position, and line pressure feedback to time every shift and to pulse the torque converter clutch on gradually instead of slamming it on. The valve body is where that strategy becomes hydraulic action: the pressure regulator and boost valves set main line pressure, the actuator feed limit valve meters the pressure that feeds the shift solenoids, and the 1-2, 2-3, and TCC circuits route pressurized fluid to the clutches, bands, and converter clutch on command. Every one of those valves rides in a bore machined into the aluminum casting, and a transmission with 150,000-plus miles on it has usually worn those bores oval, which lets fluid leak past the valve instead of applying the clutch cleanly.
The 3-4 clutch and sun shell failures are mechanical, not hydraulic, so a new valve body will not fix those by itself. Our 4L60E common problems guide walks through how to tell which failure you actually have before you order parts.
Pull codes and check the fluid first. Burnt or dark fluid with a scorched smell points at the clutches, while clean fluid and a P0741 or P0748 code points at the valve body. If you can access the line pressure tap, pressure that will not climb cleanly under throttle is the clearest hydraulic sign of bore wear. Our valve body bench walkthrough shows which bores fail first on a unit this age and how a rebuilder tests for it.
This valve body is built for the 4L60E as installed in 2001-2002 GM trucks, SUVs, and cars. GM revised the casting and solenoid pack more than once across the 4L60E's production run, so match your old unit's connector count and casting number against this listing before ordering, or send us your year, make, and VIN and we will confirm the correct version. The full lineup of 4L60E valve bodies we carry, including the years on either side of this one, is on the 4L60E parts page.
Drop the pan, unclip the internal wiring harness, and remove the valve body bolts in the sequence GM specifies so the casting does not warp against the separator plate. Keep a hand on the check balls as the unit comes down so none of them drop out of their pockets. Install a new filter and pan gasket at the same time so debris from the old valve body does not circulate into the new one, and refill with Dexron VI. If the EPC, shift, or TCC solenoids are original to the truck, a 9-piece master solenoid kit is worth installing alongside this valve body if the originals are high mileage, and the separator plate underneath it should be inspected for warping before you torque the new unit down. Let the computer relearn its shift adapts over the first several drives, or clear adapts with a scan tool to speed it up.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
By 2001 the 4L60E was running GM's OBD-II electronic control strategy, which depends on the valve body's shift and TCC circuits accurately following commanded pressure. Worn bores still produce the same P0741 and P0748 codes this listing addresses, but the solenoid pack and connector layout have to match the control era.
If the code is caused by a worn TCC regulator or isolator bore inside the valve body, yes. If the torque converter itself has failed, the converter needs to be replaced too.
It carries a 1-year warranty.
Not if the cause is a stripped sun shell, which is a mechanical failure inside the case rather than a valve body problem. Check our common problems guide to tell the two failures apart before you order.
A new filter, pan gasket, and fresh Dexron VI fluid at minimum. If the solenoids are original to the truck, a master solenoid kit is worth installing alongside it.
No. The computer relearns its shift adapts over the first several drives, and a scan tool that can clear adapts will speed that up.
