Cadillac CTS 2005-2007 Automatic Transmission 5-Speed 5L40E Remanufactured Style-B

Does harsh gear hunting and delayed reverse engagement compromise your Cadillac CTS? Fix that transmission slipping with this remanufactured CTS 5L40E Style-B transmission 10724T built for 2005 to 2007 2.8L and 3.6L 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 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 Sonnax boost valve kits, upgraded TCC regulator valves, Kolene steel plates, and BorgWarner friction packs. Replaced pump bushings preserve continuous fluid pressure. The dry unit weighs 162 lbs and ships inside a 36 by 24 by 22 inch crate.

Key Features of GM 5L40E

Independent repair shops buy GM 5L40E transmission assemblies to resolve converter shudder and delayed shifts without paying inflated dealer pricing. This commercial remanufactured transmission assembly provides smooth ratio stepping for Cadillac CTS transmission replacement projects.

- Upgraded Sonnax TCC regulator sleeve fixes torque converter shudder and lockup clutch slippage.
- Re-machined pressure regulator valve bore stops line pressure decay inside the pump 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.
- BorgWarner friction plates resist thermal glaze under demanding stop-and-go commuter traffic.
- Hardened sun gear drive shells eliminate strip failures common under hard vehicle launches.
- Refurbished solenoid group provides accurate 24 ms line pressure modulation across all throttle inputs.

AIDCO Bench Dynamometer Pressure Metrics

Every remanufactured 5L40E transmission runs on an automated AIDCO dynamometer through cold start and elevated operating temperatures. Gauges register main line pressure at 190 PSI in Drive and 260 PSI in Reverse at 1600 RPM. Electronic pressure control solenoids modulate hydraulic passages within 24 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.
