6L80 Pump 2006, new and ready to install. Fits the 6L80. Ships fast from the USA.
This listing is a new 6L80 and 6L90 bell housing pump body, the aluminum casting that replaces GM 24248031 on V8 applications from 2006 on. The "2006" in the title marks where this casting starts, not a single model year: it is the housing found behind the V8 in Silverado, Sierra, Tahoe, Suburban, Yukon, Escalade, Camaro and Corvette six-speeds. Buyers usually land here after tearing down a unit and finding a scored pump pocket, a wallowed bushing bore, a cracked bolt boss or stripped threads, and needing a clean housing rather than another used core of unknown history.
On the 6L80 the front pump is not a separate bolt-in cartridge. It is a vane pump whose rotor, slide and vanes ride in a pocket machined into this housing, driven off the torque converter hub. The pump cover with its stator support and sealing rings bolts over that pocket, and the same casting bolts the transmission to the engine. That means the housing is a hydraulic part as much as a structural one: the pocket depth and the bushing bore set how well the pump seals and how much pressure it can make, and the filter pickup bore holds the sump filter neck in place.
Gauge line pressure and compare it to what the TCM is commanding; pressure that is low across the board points to the pump side rather than a single clutch circuit. Once the unit is out, inspect the pocket and bushing bore with the rotor and slide removed. GM does not sell the 6L80 pump bushing as a stand-alone part, so a damaged bore or bushing often means replacing the housing. If the bushing wore because the converter shed debris, deal with the converter too or the new housing will see the same wear. Our 6L80 pump failure symptoms guide covers the pump cover sealing ring leak on pre-December 2008 units, the filter-in-the-pan problem, and the cracked filter on cold start, so you can tell a housing problem from a cover or valve body problem.
This casting is listed for GM 6L80 and 6L90 transmissions behind V8 engines, 2006 and up, as a replacement for housing 24248031. GM used more than one housing across the 6L family, so match the casting number on your old housing, or send us your year, engine and VIN before ordering and we will check it. Browse every 6L80 part we carry in the 6L80 collection.
Most housings get replaced during a full overhaul, so if the clutches are tired too, pair this with a 6L80E rebuild kit with pistons, frictions and filter. After the rebuild, our 6L80 service guide explains the fill and level check.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It is the new bell housing pump body casting that replaces GM 24248031. Plan to transfer or replace the rotor, slide, vanes, springs and pump cover from your unit after inspecting them, and confirm whether a bushing and front seal are installed before assembly.
No. The casting is listed for 6L80 and 6L90 V8 applications from 2006 on. Because GM used more than one housing in the 6L family, match the casting number on your old housing or send us year, engine and VIN.
GM does not sell the 6L80 pump bushing separately, and a bushing that spun or wore the bore leaves the housing out of spec. A new casting gives the pump pocket and bushing bore a fresh start.
The 6L80 and 6L90 use DEXRON VI. Fill a rebuilt unit and set the level with GM's hot check at 71-93 C (160-200 F) on the transmission temperature reading.
A front seal, the sump filter, and any worn pump internals at minimum. Inspect the torque converter for internal damage, since converter debris is the usual cause of bushing wear.
