Cadillac ATS 2016-2017 Automatic Transmission 8-Speed 8L45 3.6L RWD Remanufactured

A 185 PSI forward line pressure curve delivers positive multi-pack clutch clamping across Cadillac 3.6L LGX power bands. This remanufactured Cadillac ATS 8L45 RWD transmission carries tag 12722T for rear-wheel-drive sedans and coupes. Installers must complete a high-temperature cooler flush and perform a computer shift adaptation reset before road testing to safeguard internal friction surfaces.

Shot-peened A380 die-cast aluminum forms the longitudinal housing, checked for micro-cracks with dye penetrant around bellhousing and tailhousing mounts. Hardened planetary carrier gears transfer 335 horsepower without gear tooth pitting. Rebuilders install upgraded Sonnax pressure regulator valve sleeves, TCC control valves, Kolene steel plates, and Raybestos GPZ frictions. Replaced pump stator bushings restore hydraulic circuit balance. The dry transmission weighs 178 lbs and ships inside a 36 by 24 by 22 inch crate.

Key Features of GM 8L45

Technicians buy GM 8L45 transmission assemblies to eliminate converter slip codes without paying high dealer parts pricing. This commercial remanufactured transmission assembly provides durable gear engagement for Cadillac ATS transmission replacement projects.

- Reamed pressure regulator valve bore stops internal line pressure drops that cause shift flare.
- Upgraded TCC regulator valve sleeve eliminates torque converter clutch slip and friction shudder.
- Vacuum testing confirms 22 inHg seal across all re-machined valve body bores.
- Balanced remanufactured torque converter eliminates driveline vibration and protects front pump drive gears.
- Raybestos GPZ friction plates resist thermal glaze under demanding performance highway driving.
- Hardened output shaft splines handle full 3.6L engine output without spline twist damage.
- Updated solenoid group delivers precise 20 ms hydraulic line pressure modulation across all gears.

SuperFlow Dynamometer Diagnostic Telemetry Data

Technicians test each remanufactured 8L45 transmission on an automated SuperFlow dynamometer through cold start and elevated operating temperatures. Gauges register main line pressure at 185 PSI in Drive and 250 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 21 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 supercharged track racers, drift cars, or nitrous builds.

- Flush chassis transmission oil cooler passages with heated solvent to remove trapped friction particles.
- Fill with approved Mobil 1 Synthetic LV ATF HP fluid 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.
