4L60E Pump 2006, remanufactured and ready to install. Fits the 4L60E. Ships fast from the USA.
A 2006 Silverado 1500, Sierra 1500, Tahoe, Yukon or Suburban that takes a second or two to grab drive when hot, slips in every gear, or whines in step with engine speed often has a worn front pump. This remanufactured GM 4L60E pump for 2006 lets you bolt in a complete, bench-ready assembly instead of rebuilding a scored pump body on the bench. It carries a 1-year warranty.
The 4L60E pump is a variable-displacement vane pump bolted to the front of the case and driven by the torque converter hub. GM service information describes it as a 13-vane design: a rotor spins inside a slide that pivots on a pin, and the pressure regulator valve moves that slide to deliver only the flow the unit needs. The pump body also carries the stator support and the passages that feed the converter and the converter clutch. On a 2006 truck the PCM commands line pressure through the pressure control solenoid, but it can only trim a few psi either way to correct for wear. Once the rotor, vanes, slide or regulator bore wears, no amount of adaptive learning brings pressure back.
Put a gauge on the line pressure tap and read it at idle and under load in drive and reverse. Do not trust the scan tool PID for commanded pressure; the commanded value can look normal while actual pressure is low. Low everywhere points at the pump. Low only in reverse or under throttle points at the regulator and boost circuit. Our 4L60E pump rotor and bushing wear guide breaks down the four wear points, and 4L60E common problems and fixes covers the failures that look like pump trouble but are not.
This pump is listed for 2006 4L60E applications. That model year covers the GMT800 Silverado and Sierra 1500 plus the Tahoe, Yukon and Suburban, along with other 4L60E rear-drive GM vehicles. GM changed converter hub and stator details across the 4L60E run, so match your old pump to this one before installing: compare the bolt pattern, the converter hub bore and the stator shaft. If you want it checked first, send us your year and VIN. If your truck falls on the other side of a revision, see the 2004-2006 4L60E pump or browse the full 4L60E parts collection.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It is listed for 2006 4L60E applications, which includes the 2006 Silverado 1500 with the 4L60E. Compare the bolt pattern, hub bore and stator shaft against your old pump, or send us your VIN to confirm.
It is a remanufactured GM pump, built and tested as a complete assembly, and it comes with a 1-year warranty.
Yes. Converter apply oil passes through the pump and stator support, so a worn bushing or worn regulator can let that pressure leak and set slip codes like P0741 or P1870. Rule out the valve body and TCC solenoid too.
Use Dexron VI ATF. Pre-fill the converter and fill the case before the first start so the new pump primes.
Not always. If the clutches and band still hold and the fluid is clean, a pump replacement can be enough. If the 3-4 clutch is burnt or the pan is full of debris, plan on a full rebuild.
