Slot this remanufactured 2011 CTS 6L50 RWD transmission into your rear-wheel-drive luxury sedan bay for restored shift precision. Built for 2011 Cadillac CTS models with 3.0L LF1 direct-injection engines, this six-speed unit cures slipping gear transitions. You must clear transmission computer adaptation values and flush cooler circuits prior to putting this unit into daily road service.

Shot-peened A380 die-cast aluminum forms the longitudinal casing, inspected for stress fractures with non-destructive fluorescent dye testing. High-strength planetary pinions handle 270-horsepower V6 torque without tooth deflection. We install oversized steel pressure regulator valves, heavy-gauge 1-2-3-4 clutch wave plates, Kolene steel plates, and high-energy Raybestos GPZ friction packs. Renewed front pump stator bushings restore continuous fluid volume. The dry transmission weighs 205 lbs and ships inside a 38 by 24 by 22 inch crate.

Key Features of GM 6L50

Professional repair facilities buy GM 6L50 transmission assemblies to correct delayed drive engagement without facing steep dealership part pricing. This commercial remanufactured transmission assembly provides dependable power transfer for your Cadillac CTS 3.0L rear-wheel-drive replacement project.

- Hardened 1-2-3-4 clutch wave plate prevents fatigue failure and clutch drum destruction.
- Oversized pressure regulator valve sleeve stops hydraulic line pressure decay inside the valve body.
- Vacuum testing confirms 22 inHg seal across all reamed valve body passages.
- Balanced remanufactured torque converter eliminates driveline vibration and protects front pump bushing wear.
- Raybestos GPZ friction clutch plates maintain solid torque transfer under continuous highway cruising conditions.
- Hardened output shaft splines handle full throttle acceleration without tooth twist or stripping.
- Pre-tested internal TEHCM solenoid module ensures precise 20 ms line pressure modulation in all gears.

AIDCO Bench Dynamometer Pressure Metrics

Certified technicians test each remanufactured 6L50 gearbox on an automated AIDCO test bench through cold and hot running cycles. Gauges measure main line pressure reaching 180 PSI in Drive and 240 PSI in Reverse at 1600 RPM. Electronic shift solenoids actuate valve passages within 20 ms under computer diagnostics. Valve body hydraulic passages hold 21 inHg vacuum during static bench drawdown tests. Dyno sensors confirm zero converter clutch slip under loaded grade profiles. Fluid temperatures hold steady at 175°F.

Field Installation Guidelines Negative Filter

Turn and push the torque converter until you verify three distinct clicks into the pump drive gears. Avoid drawing the transmission against the engine block with bolts before dowels seat. Do not buy this factory calibration gearbox for drag racing builds, custom drift chassis, or nitrous swaps.

- Flush chassis radiator heat exchangers with dedicated chemical solvent to remove suspended metal dust.
- Fill with approved Dexron VI fluid until fluid spills from check plug at 40°C.
- Reset transmission shift adaptation registers using an advanced scan tool before initial highway driving.

Nationwide Warranty Freight Manifest Details

Your purchase includes a nationwide 3-Year/100,000-Mile warranty covering mechanical breakdown and internal hydraulic control failure. The heavy wood crate holds a balanced torque converter, technician installation checklist, dynamometer test pass certificate, cooler flush verification card, and a pre-paid core return freight bill for prompt return transit.
