4L60E valve body for 2001-2002, remanufactured and ready to install. Ships fast from the USA.
A 2001 or 2002 Silverado, Sierra, Tahoe, Yukon, or Suburban running a 4L60E that shudders at highway speed, flares on the 1-2 or 2-3 shift, or will not get out of 3rd gear is almost always pointing at the valve body before anything else. This is a remanufactured 4L60E valve body built specifically for 2001-2002 production, bench-verified before it ships.
By 2001-2002, every 4L60E is running GM's EC3-era control strategy, with the pressure regulator and boost valves setting line pressure, the 1-2 and 2-3 shift valves routing it to the clutches and bands, and the TCC circuit applying the torque converter clutch under command from solenoids the computer times. All of that hydraulic work happens in machined aluminum bores, and years of fluid passing through those bores at pressure wears them out of round. Once a bore wears, pressure leaks past the valve instead of building clean apply pressure, and the transmission starts covering for it with soft, late, or flared shifts.
Dark or burnt fluid means the clutch packs need attention regardless of what the valve body does, so check fluid condition and pull any stored codes before you order. Our valve body wear and bench fix guide covers the vacuum test technicians use to confirm which circuit inside the casting has actually worn, and the 3-4 clutch and AFL valve guide is worth reading if the complaint is specifically no 3rd or 4th rather than general flare.
This valve body is built for 2001-2002 4L60E production. These two years share the same control layout and connector setup, so fitment is more consistent than on earlier model years that span a mid-cycle electronics change. Still, match the casting number on your old unit against the listing photos before ordering, since GM made running changes within model years on some applications, or send us your vehicle and VIN and we will confirm it. Every other 4L60E year we carry, including the 2003-2005 assembly with harness right after this one, is on the 4L60E parts page.
Drop the pan, unplug the internal harness, and remove the valve body bolts in GM's specified sequence while holding the separator plate up against the case so the check balls stay seated. Set the replacement with a new filter and pan gasket so debris from the old unit does not circulate into the fresh valve body, torque to spec, and refill with Dexron VI. If the pump has any wear on it too, a pump rotor kit is worth doing in the same job rather than coming back into the transmission twice. Let the computer relearn its shift adapts over the next several drives.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Yes, these two model years share the same control layout and connector setup. Match the casting number on your old unit to the listing photos, or send us your vehicle and VIN to confirm.
If the shudder is from worn TCC circuit bores inside the valve body, yes. A worn converter or contaminated fluid can cause similar symptoms and needs separate attention.
Remanufactured, with the worn valves updated and the unit bench-verified before it ships.
P0741 for TCC performance issues and P0748 for pressure control solenoid problems are common, though a scan tool reading is the only way to know for certain on your truck.
Replace the filter and pan gasket, refill with Dexron VI, and inspect the pump if it has not been serviced recently.
Not required. The computer relearns its shift adapts over several drives on its own, though a scan tool can reset adapts immediately if you have one available.
