4L60E Pump 2007, remanufactured and ready to install. Fits the 4L60E. Ships fast from the USA.
Model year 2007 is the year GM sold two generations of pickups side by side: the carryover Silverado and Sierra Classic and the redesigned trucks, plus the new Tahoe, Yukon and Suburban. Plenty of both carry the 4L60E, and when one starts flaring, slipping or engaging late, the front pump is a prime suspect. This remanufactured 4L60E pump for 2007 arrives assembled and ready to install, and it carries a 1-year warranty.
Every psi of pressure in a 4L60E starts at the pump. The converter hub turns an inner rotor, and its vanes sweep oil through a chamber formed by a pivoting slide. When pressure is high enough, the pressure regulator valve pushes the slide toward minimum displacement; when the unit needs more, the slide swings back out. That design saves power, but it adds wear points: the rotor and vane rings, the slide and pivot pin, the regulator valve bore, and the rear stator support bushing that holds the converter hub concentric and seals the converter feed passages. Sonnax notes that the original stator bushing in this family commonly wears out early, and when it goes, the pump is loaded unevenly and converter oil cross-leaks.
Line pressure tells you more than any other single test. Read it with a mechanical gauge in drive and reverse at idle, then at stall. If reverse is far below spec, the regulator valve bore is likely worn; if pressure is low across the board, the rotor, vanes or slide are worn. Rule out a clogged filter or low fluid first. The pump rotor and bushing wear guide shows each wear point, and the overrun clutch guide helps separate a slipping clutch from a pressure problem.
Listed for 2007 4L60E applications. Because 2007 straddles two truck generations, confirm against the pump you remove: the same bolt pattern, converter hub bore and stator shaft. If anything does not match, stop and send us your year and VIN. Other years are listed separately, including the 2006 4L60E pump, and the full lineup is in the 4L60E collection.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It is listed for 2007 4L60E applications. Because both truck generations were sold that year, compare the bolt pattern, hub bore and stator shaft against your old pump, or send us your VIN before installing.
A worn pressure regulator valve bore in the pump can leave reverse boost pressure well below spec. A line pressure test in reverse will confirm it before you replace parts.
Only if the converter hub is grooved or the converter is full of debris. A damaged hub wears out the new pump bushing and seal quickly.
Dexron VI ATF. Pre-fill the converter and the case so the pump primes on startup, then check the level hot.
Yes, this remanufactured pump comes with a 1-year warranty.
