Cadillac CTS 2014-2015 Automatic Transmission 6-Speed 6L45 3.6L AWD Remanufactured

Does harsh 1-2-3 shift slip and broken wave plate debris compromise your Cadillac CTS? Fix that transmission failure with this remanufactured CTS 6L45 AWD transmission 12808T built for 2014 to 2015 3.6L direct-injection models. Technicians must perform a heated cooler line flush and clear shift adaptives prior to initial road testing.

High-density A380 die-cast aluminum forms the longitudinal casing, inspected for hairline stress fractures along transfer case mounting bosses using non-destructive dye testing. Hardened steel planet gears and high-strength reaction carriers handle 3.6L V6 torque without tooth pitting. We install heavy-gauge 1-2-3-4 clutch wave plates, upgraded PR valve sleeves, Kolene steel plates, and Raybestos GPZ friction packs. Replaced pump bushings preserve continuous fluid pressure. The dry unit 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 assemblies to resolve wave plate fractures and delayed shifts without paying inflated dealer pricing. This commercial remanufactured transmission assembly provides smooth ratio stepping 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.
- Re-machined pressure regulator valve bore stops line pressure decay inside the valve body.
- Vacuum testing confirms 22 inHg seal across all reamed spool valve bores.
- Balanced remanufactured torque converter stops driveline vibration and prevents front pump bushing wear.
- Raybestos GPZ friction plates resist thermal glaze under demanding stop-and-go commuter traffic.
- Hardened transfer case splines eliminate strip failures common under hard vehicle launches.
- Refurbished internal TEHCM module provides accurate 20 ms line pressure modulation across all throttle inputs.

AIDCO Bench Dynamometer Pressure Metrics

Every remanufactured 6L45 transmission runs on an automated AIDCO 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. Electronic pressure control solenoids modulate hydraulic passages within 20 ms under computer diagnostics. Valve body passages hold 21 inHg vacuum during static bench drawdown tests. The test software logs zero converter clutch slip at cruising speeds. Fluid temperatures hold steady at 175°F.

Field Installation Directives Application Limits

Push the torque converter inward while spinning the hub to ensure complete engagement into the oil pump drive lugs. Check engine alignment dowels for burrs prior to pulling the transmission against the engine block. Do not buy this factory unit for supercharged track racers or custom engine swaps.

- Flush chassis radiator transmission cooler lines with heated solvent to clear trapped metal particulate.
- Fill with approved Dexron VI fluid while monitoring fluid level at 40°C pan temperature.
- Reset transmission shift adaptives using an advanced scan tool before highway road testing.

Nationwide Warranty Freight Manifest Inclusions

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