Cadillac Escalade 2015-2017 Automatic Transmission 8-Speed 8L90E 6.2L RWD Remanufactured

Virgin shot-peened A380 aluminum forms the foundation of this reinforced rear-wheel-drive luxury transmission. This remanufactured Escalade 8L90E RWD transmission 12672T delivers restored line pressure for 2015 to 2017 models with 6.2L V8 engines. You must replace the cooler bypass thermostat and perform a heated cooler flush before road testing to protect internal clutches under heavy towing.

Clean shot-peened A380 die-cast aluminum encloses the heavy gear train, inspected for hairline casing fissures using fluorescent dye testing. High-strength planetary gears transfer 420 horsepower without tooth spalling or carrier distortion. Rebuilt internals include upgraded pressure regulator sleeves, reamed TCC bores, Kolene reaction steels, and Raybestos GPZ friction packs. Renewed front pump stator bushings prevent circuit cross-leaks. The dry gearbox weighs 210 lbs and ships inside a 38 by 24 by 22 inch crate.

Key Features of GM 8L90E

Professional mechanics buy GM 8L90E transmissions to eliminate harsh gear hunting and converter shudder without facing steep dealer part pricing. This commercial remanufactured transmission assembly supplies reliable torque capacity and restored shift quality for Cadillac Escalade replacement projects.

- Re-machined pressure regulator valve bore stops line pressure decay and harsh 1-2 shifts.
- Updated TCC regulator valve sleeve eliminates torque converter clutch slip and friction shudder.
- Vacuum testing guarantees minimum 22 inHg seal across all control circuits.
- Balanced remanufactured torque converter prevents front stator bushing galling under heavy acceleration.
- Raybestos GPZ friction discs prevent thermal breakdown during stop-and-go heavy trailer towing.
- Hardened output shaft splines handle full throttle acceleration without tooth twist or stripping.
- Refurbished internal solenoid pack ensures factory 20 ms response timing across all gears.

AIDCO Bench Dynamometer Pressure Metrics

Technicians secure each remanufactured transmission to an AIDCO test bench to verify internal line pressure across every gear ratio. Pressure readings log 195 PSI in Drive and 255 PSI in Reverse at 1600 RPM. Electronic shift solenoids actuate valve passages within 20 ms under live computer diagnostics. Hydro-testing proves a steady vacuum hold of 21 inHg on all reamed valve body ports. Dyno computer sensors verify zero converter clutch slip under loaded test programs. Fluid testing at 180°F confirms proper hydraulic flow without case leaks.

Installation Directives Field Application Limits

Turn and push the torque converter until you verify three distinct clicks into the pump drive gear lugs. Avoid drawing the transmission against the engine block with bolts before dowels seat. Do not buy this factory spec transmission for turbocharged builds, nitrous setups, or track drag competition.

- Flush chassis radiator heat exchangers with dedicated 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 data using a diagnostic scan tool before highway driving.

Nationwide Warranty Freight Manifest Details
