Slot this remanufactured Cadillac ATS 8L45 AWD transmission into your turbo sport sedan bay for instant torque recovery. Built for 2019 models with 2.0L LTG turbo engines, this eight-speed unit cures low-speed converter shudder. 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 all-wheel-drive casing, inspected for stress fractures with non-destructive fluorescent dye testing. High-strength planetary pinions handle 272-horsepower turbocharged torque without tooth deflection. We install oversized steel pressure regulator valves, Sonnax TCC regulator sleeves, Kolene steel plates, and high-energy Raybestos GPZ friction packs. Renewed front pump stator bushings restore continuous fluid volume. The dry transmission weighs 185 lbs and ships inside a 36 by 24 by 22 inch crate.

Key Features of GM 8L45

Professional repair facilities buy GM 8L45 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 ATS turbo all-wheel-drive replacement project.

- Oversized pressure regulator valve sleeve stops hydraulic line pressure decay inside the valve body.
- Re-machined TCC regulator valve bore eliminates torque converter clutch slip and friction shudder.
- 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 turbocharged boost conditions.
- Hardened transfer case output splines resist wear under aggressive all-wheel-drive vehicle launches.
- Precision stator support bushings ensure uninterrupted hydraulic fluid feed to the converter clutch.

AIDCO Bench Dynamometer Pressure Metrics

Certified technicians test each remanufactured 8L45 gearbox on an automated AIDCO test bench through cold and hot running cycles. Gauges measure main line pressure reaching 185 PSI in Drive and 250 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 Mobil 1 Synthetic LV ATF HP fluid at 40°C pan temperature.
- Reset transmission shift adaptation registers using an advanced scan tool before initial highway driving.
