6T80E 2016 Cadillac XTS 3.6L AWD/4WD – Remanufactured Automatic Trans

Description

Locking internal clutch friction plates under 300 PSI pump force while directing 380 lb-ft torque, this Cadillac XTS AWD Remanufactured Transmission provides renewed performance for 2016 Cadillac XTS 3.6L all-wheel-drive sedans. Commercial passenger fleets eliminate harsh gear hunting throughout demanding city transit schedules.

A380 die-cast aluminum transmission housings resist structural distortion under sustained full-power highway merging. Every remanufactured valve body receives hard-anodized Sonnax sleeves in high-wear bores to halt hydraulic fluid cross-leakage. Radial fluid cooling grooves molded into carbon friction clutch discs route heat into 9.8 quarts of DEXRON-VI fluid. Dry weight measures 235 lbs with factory-standard 3/8-inch inverted flare cooler fittings for fast, leak-free radiator hookup.

Key Features of Cadillac XTS

Premature friction plate wear during constant metropolitan passenger transit forces fleet supervisors to buy Cadillac XTS remanufactured transmission units. Recalibrated electro-hydraulic valve bodies prevent internal cross-circuit leaks to maintain smooth acceleration under load.

• 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 Cadillac XTS 6T80E package keeps fluid delivery stable during intense stop-and-go driving conditions
• Computer-balanced internal torque converters eliminate vibration through cabin footwells during highway travel
• Dyno-tested powertrain modules restore original factory acceleration standards across all operating ranges

Hydraulic Line Pressure Calibrations

A 4.48:1 first gear step transitions through six forward ratios toward a 0.74:1 overdrive step that drops highway engine revolution counts. Operating clutch fluid circuits maintain 220 to 300 PSI pump line pressure to clamp internal clutches without slipping. Transmission fluid sump temperatures remain within an optimal 160°F to 190°F range on summer highways. Internal fluid pathways evacuate 900 BTU per minute of heat energy straight to the radiator cooler. Continuous input torque ratings sustain 380 lb-ft at 4,800 RPM without fatigue.

Differential Carrier Spline Alignment

Transferring engine rotation straight through precision-ground differential sun gears, the 35-tooth output spline resists driveline lash. High-tensile alloy case construction prevents differential pin migration during severe wheel slip episodes. Internal parking pawl mechanisms hold 1,650 lb-ft of static rollback torque on 18-degree loading docks. Precision dial indicators measure total output hub runout under 0.003 inches total indicator reading.

Transmission Adaptation Maintenance Protocols

Reset internal shift adapts via scan tool before operating the vehicle in regular passenger 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 electronic control modules to monitor line pressure variance and torque converter clutch slippage
• Every 30 days check fluid level on level ground at 175°F to ensure adequate pump suction head
• Every 30,000 miles drain contaminated DEXRON-VI fluid and replace auxiliary cooling filters to protect internal components

Commercial Fleet Crate Package

Uninterrupted fleet mobility is backed by a 3-Year / 100,000-Mile commercial fleet warranty covering parts plus labor nationwide. Every secure shipping crate contains one fully remanufactured transaxle unit, a balanced torque converter, cooler line seal washers, installation instructions, plus verified dynamometer test printouts.
