Cadillac ATS CTS 2016-2017 Automatic Transmission 8-Speed 8L45 2.0L AWD Remanufactured

Description

Stop-and-go commuter traffic and winter all-wheel-drive highway driving demand consistent hydraulic transmission line pressure stability. This remanufactured GM 8L45 AWD transmission 12719T restores factory gear engagement for 2016 to 2017 Cadillac ATS and CTS 2.0L LTG turbo models. Installers must flush the external transmission oil cooler and clear adaptation tables before releasing the sedan.

Shot-peened A380 die-cast aluminum forms the bellhousing and transfer case adapter, inspected with magnetic particle dye after abrasive shot blasting. Hardened planetary carrier pins resist high shear loads from GM 2.0L turbo engines. We install updated actuator valve sleeves, Sonnax TCC boost kits, Kolene steel reaction plates, and Raybestos GPZ friction packs. Renewed front pump stator bushings prevent internal fluid leakage. The dry assembly weighs 185 lbs and ships in a 36 by 24 by 22 inch crate.

Key Features of GM 8L45

Automotive shops buy GM 8L45 transmission gearboxes to stop delayed forward engagement without paying inflated dealership pricing. This commercial remanufactured transmission assembly provides reliable open-road driving for your Cadillac CTS transmission replacement project.

• Oversized pressure regulator valve sleeve stops line pressure drops inside the valve body casting.
• CNC-reamed valve body bores hold 22 inHg on calibrated vacuum test benches.
• Raybestos GPZ friction plates resist thermal loads encountered during aggressive spirited sedan driving.
• Balanced remanufactured torque converter stops drivetrain shudder while protecting front oil pump gears.
• Hardened transfer case splines eliminate strip failure under continuous all-wheel-drive torque delivery.
• Upgraded TCC regulator sleeve prevents fluid cross-bleed during rapid throttle transitions.
• Precision stator support bushings maintain consistent hydraulic fluid feed to the converter clutch.

SuperFlow Dynamometer Diagnostic Telemetry Data

Technicians test every remanufactured 8L45 gearbox 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 modulated shift solenoids show actuation response times under 20 ms without mechanical valve hang. Critical valve body bores sustain 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 Protocols Negative Filter

Turn and push the torque converter until you verify three distinct clicks into the oil pump drive gear. Verify engine block dowel alignment before drawing bellhousing bolts tight to the block. Do not buy this factory unit for high-boost turbo conversions, track drift builds, or nitrous drag racing.

• Flush chassis transmission cooler lines with heated pressurized solvent to clear friction sediment.
• Fill with approved Mobil 1 Synthetic LV ATF HP fluid at 40°C pan temperature.
• Reset transmission shift adaptives using an advanced diagnostic scanner prior to road testing.

Nationwide Warranty Freight Manifest Inclusions

Your transmission purchase brings a nationwide 3-Year/100,000-Mile warranty covering mechanical breakdown and hydraulic valve body defects. 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.
