6L45E valve body for Up-To-2010, remanufactured and ready to install. Ships fast from the USA.
If your up-to-2010 Cadillac CTS, STS, Chevrolet Camaro V6 or BMW 1/3/5-Series with the GA6L45R transaxle is shifting harsh, slipping, or has gone into limp mode with a pressure or solenoid code, the valve body is a known wear point on the 6L45 family. This is a remanufactured valve body built on casting 9405/9581, tested before it ships, so you install a verified unit instead of reusing a worn core.
The 6L45 is a 6-speed, clutch-to-clutch rear-wheel-drive automatic shared with the related 6L50, 6L80 and 6L90 across GM's RPO lineup, and the valve body routes line pressure through precision bores to each clutch, timed by the shift and pressure-control solenoids it carries. ATRA's technical writeup on this family identifies a single check ball in the upper valve body that feeds the 1-2-3-4 clutch circuit as a recurring failure point across the whole 6L45/50/80/90 group, and Sonnax's repair-tip article on the same family documents the line pressure signatures - including a flat 60-68 psi reading - that distinguish a stuck line pressure solenoid from a missing boost valve.
Scan for codes and note whether the complaint is a shift-quality problem or a no-movement/slip condition - GM has documented that this family's upper valve bodies are unique by transmission RPO, and installing the wrong one for your specific unit causes no reverse or no second gear, so confirm your exact RPO (MYA for 6L45, MYB for 6L50) before ordering rather than matching by casting look alone. Our 6L45 limp mode guide walks through isolating a hydraulic valve body fault from a wiring or TCM fault before you spend money on parts.
This listing covers the 6L45 as installed in up-to-2010 Cadillac CTS and STS, Chevrolet Camaro V6, and the BMW 1/3/5-Series applications that use the GA6L45R version of this transaxle, built on casting 9405/9581. Because GM ran this upper valve body as RPO-specific hardware across the 6L45/50/80/90 family - not interchangeable between them despite looking alike - match your RPO code or send your VIN so we can confirm this is the correct casting for your application before you order. The full 6L45/6L50 parts collection has everything else we stock for this platform.
Drop the pan and filter at the same time as the valve body swap so debris from the old unit does not circulate into the new one, torque the valve body bolts in sequence to spec, and refill with Dexron VI ATF only. Clear codes and run the TCM's adaptive relearn after the swap so the computer re-times clutch fill against the new unit rather than the worn one. If your original complaint was a stored solenoid code with otherwise normal shifts rather than a mechanical no-move condition, a solenoid kit paired with fresh fluid may be the cheaper fix, and a shift kit or pump are worth checking if clutch fill timing or line pressure volume was part of the original diagnosis.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No - GM built the upper valve body on this family as RPO-specific hardware (MYA for 6L45, MYB for 6L50, and so on). The units look alike but installing the wrong one causes no reverse or no second gear, so confirm your RPO code before ordering.
Harsh or flared shifts, slipping between gears, no forward movement or a slip from a stop, and limp mode with a stored pressure-control or shift-solenoid code.
Casting 9405/9581, remanufactured and tested with the correct updates before it ships.
Dexron VI ATF only. Clear codes and run the TCM's adaptive relearn after the swap so clutch fill timing re-learns against the new valve body.
Not necessarily. A solenoid kit paired with fresh fluid and filter can fix a solenoid-only fault for less than replacing the whole valve body.
