Cadillac CTS 2012-2013 Automatic Transmission 6-Speed 6L50 3.0L AWD Remanufactured

Virgin shot-peened A380 aluminum forms the foundation of this reinforced all-wheel-drive luxury transmission. This remanufactured CTS 6L50 AWD transmission 12786T delivers restored line pressure for 2012 to 2013 Cadillac CTS models with 3.0L direct-injection engines. You must replace the cooler bypass valve and perform a heated cooler flush before road testing to protect internal clutches.

Clean shot-peened A380 die-cast aluminum encloses the heavy gear train, inspected for hairline casing fissures using fluorescent dye testing. High-strength planetary gears transfer 270 horsepower without tooth spalling or carrier distortion. Rebuilt internals include upgraded 1-2-3-4 clutch wave plates, reamed pressure regulator sleeves, Kolene reaction steels, and Raybestos GPZ friction packs. Renewed front pump stator bushings prevent circuit cross-leaks. The dry gearbox weighs 215 lbs and ships inside a 38 by 26 by 24 inch crate.

Key Features of GM 6L50

Professional mechanics buy GM 6L50 transmissions to eliminate harsh gear hunting without facing steep dealer part pricing. This commercial remanufactured transmission assembly supplies reliable torque capacity and restored shift quality for Cadillac CTS all-wheel-drive 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 transfer case splines handle heavy all-wheel-drive curb weight without tooth strip damage.
- 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.

Installation Directives Field Application Limits

Turn and push the torque converter until you verify three distinct clicks into the pump drive gear lugs. Avoid drawing the transmission against the engine block with bolts before dowels seat. Do not buy this factory spec transmission for turbocharged builds, nitrous setups, or track drag competition.

- Flush chassis radiator heat exchangers with dedicated solvent to remove suspended metal dust.
- Fill with approved Dexron VI fluid while monitoring fluid temperature with diagnostic tools.
- Reset transmission shift adaptation data using a diagnostic scan tool before highway driving.

Nationwide Warranty Freight Manifest Details
