Cadillac CTS 2012-2013 Automatic Transmission 6-Speed 6L50 3.6L RWD Remanufactured

Harsh 2-3 shift flares and broken wave plate metal debris indicate severe clutch drum failure inside your Cadillac. Replace that damaged gearbox with this remanufactured 2012-2013 CTS 6L50 RWD transmission engineered for 3.6L LFX rear-wheel-drive sedans. Technicians must perform a heated cooler flush and run an adaptive relearn right after bolting the bellhousing.

Shot-peened A380 die-cast aluminum forms the longitudinal casing, inspected with fluorescent dye for stress cracks along rear tailhousing mounting flanges. Four planetary gear carriers transfer 318 horsepower without carrier deflection or gear tooth spalling. Rebuilders install shot-peened 1-2-3-4 wave plates, Kolene salt-bath nitrided steel plates, and Raybestos GPZ friction discs. Precision stator bushings eliminate internal hydraulic cross-leaks. The dry transmission weighs 205 lbs and ships inside a 38 by 24 by 22 inch crate.

Key Features of GM 6L50

Independent repair shops buy GM 6L50 transmissions to stop harsh shift flares without paying inflated dealership parts pricing. This commercial remanufactured transmission assembly provides positive rear-wheel-drive torque distribution for Cadillac CTS transmission replacement projects.

- Heavy-duty 1-2-3-4 clutch wave plate eliminates premature fatigue fracture under heavy engine torque.
- Updated pressure regulator sleeve prevents line pressure drops that trigger harsh shifts.
- Vacuum testing guarantees minimum 22 inHg seal across all control circuits.
- Balanced remanufactured torque converter prevents front stator bushing galling under heavy acceleration.
- Raybestos GPZ friction discs prevent thermal breakdown during stop-and-go commuter traffic driving.
- Hardened output shaft splines handle full throttle acceleration without tooth twist or stripping.
- Refurbished internal TEHCM module ensures factory 20 ms response timing across all gears.

AIDCO Bench Dynamometer Pressure Metrics

Technicians secure each remanufactured transmission to an AIDCO test bench to verify internal line pressure across every gear ratio. Pressure readings log 180 PSI in Drive and 240 PSI in Reverse at 1600 RPM. Electronic shift solenoids actuate valve passages within 20 ms under live computer diagnostics. Hydro-testing proves a steady vacuum hold of 21 inHg on all reamed valve body ports. Dyno computer sensors verify zero converter clutch slip under loaded test programs. Fluid testing at 180°F confirms proper hydraulic flow without case leaks.

Field Installation Protocols Negative Filter

Turn and push the torque converter until you verify three distinct clicks into the oil pump drive gear lugs. Verify engine block dowel alignment before drawing bellhousing bolts tight to the block. Do not buy this factory unit for high-boost turbo conversions, track drift builds, or nitrous drag racing.

- Flush chassis radiator heat exchangers with dedicated solvent to remove suspended metal dust.
- Fill with approved Dexron VI fluid until fluid level reaches the check plug at 40°C.
- Reset transmission shift adaptation data using a diagnostic scan tool before highway driving.

Nationwide Warranty Freight Manifest Inclusions

Your transmission purchase brings a nationwide 3-Year/100,000-Mile warranty covering mechanical breakdown and hydraulic valve body defects. 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.
