6T70 2013-2016 Buick LaCrosse & Cadillac XTS 3.6L AWD/4WD – Remanufactured 6-Speed Automatic Trans

Description

Channeling 280 lb-ft of continuous input torque straight toward all-wheel-drive transfer units under 290 PSI pump force, this Buick Cadillac AWD Remanufactured Transmission resolves gear slip on 2013 to 2016 Buick LaCrosse plus Cadillac XTS 3.6L models. Executive livery fleets secure dependable traction across icy winter routes.

Heat-treated A380 die-cast aluminum casing walls prevent housing deflection under heavy all-wheel torque transfers. Hard-anodized Sonnax valve bore sleeves combine with micro-polished separator plates to eliminate hydraulic pressure bleed-off in primary clutch circuits. Carbon-metallic friction plates feature radial cooling grooves that evacuate thermal energy into 9.5 quarts of DEXRON-VI fluid. Operating at a dry weight of 228 lbs, this transaxle integrates dual 3/8-inch inverted flare cooler ports for sustained cooling balance.

Key Features of Buick Cadillac 6T70

Clutch slip during high-load municipal transit schedules prompts maintenance supervisors to buy Buick Cadillac remanufactured transmission units. Factory-upgraded hydraulic valve bodies restore crisp gear transitions under continuous all-wheel-drive power splits.

• A 4.48:1 first gear step provides crisp low-end torque multiplication for heavy vehicle acceleration
• Tolerances inside the ductile iron planetary carrier remain under 0.0025 inches to halt gear whine
• Operating friction circuits use carbon-metallic plates that resist glazing during high-heat operation
• Channeling fluid through remanufactured valve bodies stops shift hesitation between second and third gears
• The Buick Cadillac 6T70 platform delivers balanced oil feed to clutches under severe operating conditions
• Induction-hardened 8620 steel planetary gears resist tooth fatigue under repeat wide-open throttle events
• Computerized dyno hydro-pulse testing verifies solenoid pressure response curves prior to crate packaging

Torque Management Fluid Dynamics

Six forward gear steps progress from a deep 4.48:1 low gear up to a fuel-efficient 0.74:1 top overdrive ratio. Operating clutch fluid circuits maintain 215 to 290 PSI pump line pressure to clamp internal clutches without slipping. Operating sump fluid temperatures remain between 160°F and 190°F during hot summer driving shifts. Transmission heat dissipation reaches 860 BTU per minute through high-volume external cooler circuits. Input torque capacity handles 280 lb-ft at 4,800 RPM across demanding fleet shuttle shifts.

All Wheel Drive Spline Interface

Interfacing with the transfer case drive collar, the precision-machined output spline prevents driveline lash under rapid power transfers. Ductile iron case extensions withstand torque deflection during abrupt front-to-rear traction shifts. The internal mechanical parking pawl resists 1,580 lb-ft of static holding torque on steep commercial grades. Output shaft axial runout checks confirm alignment under 0.0028 inches total indicator reading.

Transmission Adaptation Maintenance Protocols

Execute complete TCM shift adaptation relearn routines before putting vehicles into commercial service. This transmission is not engineered for track drag racing, extreme rock crawling, or gross combined vehicle weights exceeding factory chassis tow limits.

• Each shift scan transmission control module data streams to verify correct torque converter lockup slip rates
• Every 30 days check fluid color and saturation levels on level shop floors at operating temperature
• Every 30,000 miles drain sump fluid and clean pan magnets to prevent metallic debris from scoring valve bores

Nationwide Fleet Warranty Coverage

Commercial fleet operations receive complete coverage through our 3-Year / 100,000-Mile commercial fleet warranty on internal components. Crated shipments include one remanufactured transmission, an engine-balanced torque converter, replacement cooler connection o-rings, complete technical documentation, plus stamped dyno inspection charts.
