AW55-50SN 2002-2003 Saturn Vue 3.0L FWD – Remanufactured 5-Speed Automatic Trans

Description

Pulse-width linear solenoids respond within 40 milliseconds to execute positive gear shifts across high-demand urban courier transit routes without shift flare. The Saturn Vue AW55-50SN Remanufactured Automatic Transmission powers 2002 to 2003 Vue 3.0L front-drive platforms. Each remanufactured unit undergoes dynamometer load testing to ensure precise gear changes during stop-and-go regional delivery schedules.

Thick-wall A380 die-cast aluminum housing sections prevent casing flex under maximum engine acceleration. Remanufactured valve bodies incorporate vacuum-tested Sonnax hard-anodized bore sleeves to prevent line pressure drop under elevated summer operating temperatures. Carbon-metallic friction clutches combine with surface-ground steel reaction plates. Specifications feature quick-connect cooler fittings, 7.6 quarts JWS 3309 fluid capacity, and 183 lbs dry weight.

Key Features of Saturn Vue AW5550SN

Wholesale fleet accounts buy Saturn Vue AW55-50SN remanufactured transmission components to resolve harsh garage shifts across delivery fleets. Restored linear solenoids and remanufactured valve bodies guarantee dependable gear selection across high-frequency urban routes.

• Sonnax hard-anodized valve bore sleeve inserts eliminate internal pressure loss across shift control valves
• Thermal-resistant carbon friction materials eliminate clutch disc slipping during continuous fleet transit
• Computer-balanced torque converter units eliminate driveline resonance at elevated highway speeds
• Ground-tooth Saturn Vue AW5550SN planetary gear sets maintain exact mesh tolerances under load
• Variable-displacement front oil pumps maintain 260 PSI pressure stability under heavy throttle demand
• Induction-hardened steel reaction plates resist heat checking under high-temperature braking events
• Bottom-access fluid pan magnets pull circulating ferrous metal particulate from oil flow

Dynamic Drivetrain Ratio Specifications

Operating line pressures span from 195 to 260 PSI across all operational gear selections under maximum load. Transmission sump temperatures hold inside an optimal 165°F to 185°F range during severe commercial use. Input torque limits support 242 lb-ft at 3,200 RPM under severe commercial fleet applications. Hydraulic fluid loops reject up to 410 BTU per minute through vehicle cooling systems. Forward gear ratios measure 4.77:1 first, 3.00:1 second, 1.96:1 third, 1.32:1 fourth, and 1.02:1 fifth.

Front Drive Axle Splines

Dual 24-spline internal differential outputs accept original equipment front halfshafts without driveline vibration. Mechanical differential components withstand 1,150 lb-ft static torque during sudden traction recovery events. Axle seal face runout measures within 0.0013 inches on precision dial indicators to protect differential seals.

Pre-Deployment Transmission Operating Rules

Technicians must perform TCM adaptive relearn protocols using professional scan tools following unit installation before vehicle service deployment. This transmission is not engineered for full-throttle drag strip launches, engine software modifications exceeding factory limits, or towing beyond chassis ratings.

• Inspect external cooler line connections and harness connectors every 50 hours
• Drain transmission fluid and inspect pan magnet accumulations every 30,000 miles
• Perform complete transmission fluid flushes with approved JWS 3309 fluid every 12 months

Standard Crate Fleet Manifest

This drivetrain investment carries a 3-Year / 100,000-Mile commercial fleet warranty contract for commercial fleet operations. The wooden crate contains a complete remanufactured transmission unit, precision-balanced torque converter, replacement cooler line clip seals, and a verified technician bench test document.
