Cadillac Escalade GMC Yukon 2018 Automatic Transmission 10-Speed 10L80E 6.2L 4×4 Remanufactured

Clutch-to-clutch shift timing and ten-speed planetary gear reduction deliver positive torque transfer across high-output 6.2L V8 power bands. This remanufactured GM 10L80E 4×4 transmission 12690T provides direct replacement for 2018 Cadillac Escalade and GMC Yukon models. You must flush cooler lines with heated solvent and reset adaptation values before completing your initial road evaluation.

Shot-peened A380 die-cast aluminum forms the longitudinal casing, inspected through non-destructive dye penetrant for bellhousing stress fractures. Four planetary gear carriers handle 420 horsepower without gear deflection or spline wear. We install upgraded CDF clutch drum retaining sleeves to stop bushing migration, reamed pressure regulator sleeves, Kolene steel plates, and high-energy Raybestos GPZ friction packs. Replaced pump stator bushings maintain constant line pressure. The dry transmission weighs 230 lbs and ships inside a 38 by 26 by 24 inch crate.

Key Features of GM 10L80E

Technicians buy GM 10L80E transmission units to eliminate harsh shift flares and CDF drum bushing failures without paying extreme dealer pricing. This commercial remanufactured transmission assembly provides refined gear changes and dependable torque delivery for your Cadillac Escalade transmission replacement project.

- Retained CDF clutch drum sleeve prevents bushing walk that causes severe gear slip.
- Upgraded pressure regulator valve sleeve stops hydraulic pressure spikes inside the valve body.
- Re-machined valve body passages hold 22 inHg during calibrated vacuum tests.
- Dynamically balanced remanufactured torque converter stops driveline vibration and protects front pump bushings.
- Raybestos GPZ friction plates resist extreme thermal glaze during prolonged heavy towing.
- Hardened four-wheel-drive transfer case splines handle full throttle acceleration without tooth twist.
- Pre-tested internal solenoid module ensures precise 20 ms line pressure modulation across all ten gears.

SuperFlow Dynamometer Diagnostic Telemetry Data

Technicians subject every remanufactured 10L80E gearbox to hot and cold testing cycles on a SuperFlow transmission dyno. Pressure gauges verify main hydraulic line pressures holding 200 PSI in Drive and 260 PSI in Reverse at 1600 RPM. Electronic shift solenoids switch circuits within 20 ms without spool valve hang. Valve body circuits hold 20 inHg vacuum on precision bench gauges. The test program validates zero torque converter clutch slip at cruising speed. Thermal imaging cameras confirm leak-free front pump and transfer case extension seals under load.

Field Installation Directives Negative Filter

Spin the torque converter inward through three positive gear drops until the converter clears the front bellhousing face. Check engine block dowels for corrosion before bolting the bellhousing flat. Do not buy this factory calibrated unit for twin-turbo custom engine builds, manual swaps, or track race chassis.

- Flush cooler lines with hot chemical solvent to clear burned friction clutch sediment.
- Fill with approved Dexron ULV fluid through the fill port at 40°C pan temperature.
- Clear transmission adaptation registers using diagnostic software before taking the vehicle on highways.
