5L40E 2004-2009 Cadillac SRX 3.6L AWD/4WD – Remanufactured 5-Speed Automatic Trans

Description

Configured for luxury crossover platforms, this Cadillac SRX 2004-2009 Remanufactured Transmission distributes 3.6L V6 torque across all 4 wheels. The 5-Speed AWD platform supports 255 horsepower and 252 lb-ft of torque beneath a 6,500 RPM ceiling. Working hydraulic line pressure peaks at 230 PSI to prevent clutch slippage across gear changes under load.

A reinforced die-cast aluminum casing encloses carburized 8620 steel helical gear sets and 3 heavy planetary gearsets. Segmented graphite friction plates pair with laser-cut steel reaction discs to withstand continuous friction heat. The rebuilt valve body includes hard-anodized bore sleeves alongside an oversized mainline pressure regulator valve. Dry unit weight totals 198 lbs, featuring a 10.0-quart fluid sump capacity and AN-6 external cooler ports.

Key Features of Cadillac SRX

Automotive repair shops buy Cadillac SRX 2004-2009 remanufactured transmission inventory to cure torque converter clutch shudder and resolve shift flare between forward gear ranges in AWD luxury crossovers. Upgraded internal mechanical parts provide dependable power transfer under continuous highway and winter driving conditions.

• 27-spline turbine input shaft handles continuous engine torque without spline distortion.
• SRX 2004-2009 replacement valve body stops internal pressure loss during gear upshifts.
• 5 forward gear ratios provide brisk low-end acceleration alongside peaceful highway cruising.
• Direct transfer case mating flange handles four-wheel drive torque splits without mechanical bind.
• 2004-2009 SRX gear train module features ground tooth profiles to curb gear hum.
• Nitrided clutch reaction plates prevent heat coning under repeated wide-open throttle passing maneuvers.
• Computer-tested pulse-width solenoids maintain crisp gear engagement across all driving conditions.

Crossover Hydrodynamic Pressure Boundaries

Operating hydraulic circuit line pressure holds between 190 and 230 PSI via electronic pressure regulator solenoid modulation. Sump oil temperatures remain within 168°F to 195°F during continuous high-speed transit. The 5-Speed gear reduction spans from a 3.42:1 1st gear ratio down to a 0.75:1 5th gear overdrive step, lowering cabin noise levels and reducing cruising fuel consumption. High-capacity internal fluid galleries cycle lubricant through remote radiator heat exchangers to stop fluid breakdown during warm weather driving.

All-Wheel Driveline Flange Alignment

The transmission features an integrated rear splined output shaft that mates straight to the AWD transfer case input. Output shaft spline radial runout measures under 0.0015 inches using dial test indicators. The structural chassis mount pad sits 25.2 inches behind the bell housing face, aligning square with factory subframe points.

Dynamometer Shifting Load Screening

Every rebuilt transmission undergoes computerized dyno load testing with heated ATF fluid to verify shift timing, line pressure stability, and clutch holding capacity under simulated vehicle weight. This transmission is not engineered for rock crawling competition, big-turbo engine builds, or drivetrains running un-flushed transmission fluid cooling systems.

• Inspect transmission pan fluid level through inspection port every 30 operating days.
• Replace synthetic automatic transmission fluid and internal filter screen every 30,000 miles.
• Inspect transfer case mating gasket and output seals every 12 months.

Cadillac Crate Warranty Coverage

Fleet operators receive an ironclad 3-Year unlimited mileage warranty protecting against mechanical defect. The reinforced wooden freight crate holds the remanufactured 5-Speed AWD transmission, balanced lockup torque converter, transfer case mounting seal, and factory fluid filling procedure documents for certified mechanics.
