Cadillac CTS 2010 Automatic Transmission AWD 6L50 3.6L Premium Remanufactured

A 180 PSI forward line pressure curve delivers positive multi-pack clutch clamping across Cadillac 3.6L LLT direct-injection power bands. This remanufactured CTS 6L50 Premium transmission 12777T matches 2010 all-wheel-drive sedans and wagons. Installers must complete a high-temperature cooler flush and perform a computer shift adaptation reset before road testing to safeguard internal friction surfaces.

Shot-peened A380 die-cast aluminum forms the longitudinal housing, checked for micro-cracks with dye penetrant around bellhousing and transfer case adapter mounts. Hardened planetary carrier gears transfer 304 horsepower without gear tooth pitting. Rebuilders install upgraded shot-peened 1-2-3-4 wave plates, PR valve sleeves, Kolene steel plates, and Raybestos GPZ frictions. Replaced pump stator bushings restore hydraulic circuit balance. The dry transmission weighs 215 lbs and ships inside a 38 by 26 by 24 inch crate.

Key Features of GM 6L50

Technicians buy GM 6L50 transmission assemblies to eliminate wave plate fractures without paying high dealer parts pricing. This commercial remanufactured transmission assembly provides durable gear engagement for Cadillac CTS Premium transmission replacement projects.

- Heavy-duty 1-2-3-4 clutch wave plate prevents stress fracture and catastrophic drum housing failure.
- Upgraded pressure regulator valve sleeve eliminates line pressure spikes inside the valve body.
- Vacuum testing proves 22 inHg retention across all reamed spool valve bores.
- Balanced torque converter stops drivetrain shudder while protecting internal pump gears from wear.
- Raybestos GPZ high-energy frictions resist high heat glaze during demanding highway driving.
- Hardened transfer case adapter splines prevent tooth strip failure under full throttle acceleration.
- Pre-tested internal TEHCM solenoid module delivers factory 20 ms line pressure modulation in all gears.

SuperFlow Dynamometer Diagnostic Telemetry Data

Technicians test each remanufactured 6L50 transmission on an automated SuperFlow dynamometer through cold start and elevated operating temperatures. Gauges register main line pressure at 180 PSI in Drive and 240 PSI in Reverse at 1600 RPM. Pulse-width shift solenoids show actuation times under 20 ms without mechanical bind. Re-machined valve body passages hold 22 inHg vacuum under static bench tests. Dynamometer instrumentation logs zero torque converter clutch slip under loaded grade profiles. Fluid temperatures hold steady at 175°F.

Field Installation Directives Application Limits

Push the torque converter inward while rotating the hub until you verify three distinct clicks. Make sure engine alignment dowels enter the bellhousing straight without draw bolt force. Do not buy this factory replacement unit for supercharged track racers, drift cars, or nitrous builds.

- Flush chassis transmission oil cooler passages with heated solvent to remove trapped friction particles.
- Fill with approved Dexron VI fluid until it spills from check port at 40°C.
- Reset transmission adaptation registers using an advanced scan tool before highway test driving.

Standard Warranty Delivery Crate Manifest

This remanufactured transmission includes a nationwide 3-Year/100,000-Mile warranty covering mechanical breakdown and hydraulic control failure. The reinforced wooden crate contains a balanced torque converter, technician installation checklist, dynamometer test pass report, cooler flush tracking card, and a pre-paid core return freight bill for prompt return transit.
