4L70E valve body for 2006-2013, remanufactured and ready to install. Ships fast from the USA.
A 2006-2013 Silverado, Sierra, Tahoe, Yukon, or Trailblazer SS that flares on the 1-2 shift, loses 3rd or 4th gear, or throws a P0741 torque converter clutch code is almost always pointing at the 4L70E valve body, not the gear train. This is a remanufactured 4L70E valve body for 2006-2013 applications, rebuilt with updated valves in the circuits that wear the most and bench-verified before it ships, so it installs as one direct-fit assembly instead of a pile of individually sourced parts.
The 4L70E is GM's updated, heavier-duty successor to the 4L65E, and the valve body is still its hydraulic brain. It meters line pressure through the pressure regulator and boost valve, feeds the shift and pressure control (EPC) solenoids through the actuator feed limit (AFL) circuit, and applies the torque converter clutch through the TCC regulator and isolator valves, then routes the result to the 1-2, 2-3, and 3-4 shift valves. When those bores wear, line pressure and apply timing both drift, and the clutches downstream start taking damage they were never designed to absorb.
Our 4L70E 3-4 clutch failure guide covers why that clutch keeps burning on this transmission specifically.
Pull codes first - a P0741, a pressure control solenoid code, or a shift solenoid code all point at the valve body or the circuits it feeds. Check the fluid condition too, since burnt fluid means the clutches already need attention regardless of the valve body. Our 4L70E valve body testing guide walks through the bench checks a shop uses to confirm bore wear before replacing the whole assembly, and our delayed engagement guide covers the related case where the truck hesitates going into gear from park.
This valve body is built for the 2006-2013 4L70E casting and connector layout used across Silverado, Sierra, Tahoe, Yukon, Trailblazer SS, and the Cadillac and Pontiac models that shared this transmission. Confirm your application against your old unit's casting number and connector count before ordering, since GM revised this valve body within the run, or send your year, vehicle, and VIN and we will confirm fitment before it ships. Every 4L70E part we carry is listed on the 4L70E parts page.
Drop the pan, disconnect the internal harness and manual valve link, and lower the valve body straight down to keep the check balls seated. Replace the filter and pan gasket in the same service, torque the bolts in GM's sequence, and refill with Dexron VI. Because this is an electronically controlled unit, let the TCM relearn shift adapts over the first several drives after install. If your original TCC solenoid is original equipment and aging, pair this valve body with a fresh TCC solenoid, and if the pump is also original, a replacement pump addresses the other major pressure source in this generation at the same time.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Yes, it ships as a complete remanufactured assembly with its solenoids in place. It does not include the internal wiring harness or pressure switch manifold.
P0741 is a torque converter clutch performance code - the TCC is slipping or not locking as commanded. On this transmission it usually traces back to a worn TCC regulator or isolator bore in the valve body.
It covers the 2006-2013 4L70E casting used across those platforms, but confirm your old unit's casting number and connector count first, or send your year, vehicle, and VIN and we will verify before it ships.
It corrects the low line pressure and worn bores that usually cause repeat 3-4 clutch and 2-4 band failure, but if the clutch pack is already burnt it needs replacing alongside the valve body.
Refill with Dexron VI and change the filter at the same time. No reflash is required - the computer relearns shift adapts over the first several drives, or a scan tool can reset adapts sooner.
