Cadillac CTS 2014-2015 Automatic Transmission 6-Speed 6L45 2.0L AWD Remanufactured

Crisp six-speed ratio stepping and firm lockup return to your all-wheel-drive Cadillac sport sedan. This remanufactured Cadillac CTS 6L45 AWD transmission provides exact hydraulic calibration for 2014 to 2015 2.0L LTG turbo models carrying tag 12807T. You must complete a high-temperature cooler line flush and execute an adaptation reset before performing initial road tests to protect internal clutches.

Shot-peened A380 die-cast aluminum forms the longitudinal transmission housing, verified crack-free through magnetic particle inspections. Steel planet pinions mesh with reaction sun gears to manage 272-horsepower turbocharged torque without excessive lash. We install oversized pressure regulator valves, heavy-gauge 1-2-3-4 wave plates, Kolene steel plates, and high-energy Raybestos GPZ frictions. Renewed stator bushings restore internal fluid balance. The dry transmission weighs 195 lbs and ships inside a 36 by 24 by 22 inch crate.

Key Features of GM 6L45

Independent repair shops buy GM 6L45 transmission units to restore positive forward engagement without paying high dealership parts pricing. This commercial remanufactured transmission assembly provides durable gear selection for Cadillac CTS turbo all-wheel-drive replacement projects.

- Heavy-duty 1-2-3-4 clutch wave plate eliminates premature fatigue fracture under turbo boost torque.
- Oversized pressure regulator valve sleeve stops hydraulic pressure loss inside the valve body casting.
- Hydro-tested valve body circuits hold 22 inHg vacuum during decay leak checks.
- Balanced remanufactured torque converter eliminates driveline vibration and prevents front pump bushing wear.
- Raybestos GPZ friction clutch plates ensure solid torque transfer under continuous highway cruising conditions.
- Hardened transfer case splines handle heavy all-wheel-drive curb weight without tooth strip damage.
- Pre-tested internal TEHCM solenoid module ensures precise 20 ms line pressure modulation in all gears.

SuperFlow Dynamometer Diagnostic Telemetry Data

Technicians test each remanufactured 6L45 gearbox 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 high-boost modified track builds, 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 plug at 40°C pan temperature.
- 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.
