AW55-50SN 2005-2006 Chevrolet Equinox, Pontiac Torrent 3.4L FWD – Remanufactured 5-Speed Automatic Trans

Description

Eliminate neutral-to-drive engagement delay and clutch slip under 260 PSI line pressure thresholds across demanding metropolitan passenger routes. The GM AW55-50SN Remanufactured Automatic Transmission fits 2005 to 2006 Chevrolet Equinox and Pontiac Torrent 3.4L front-wheel drive crossovers. Rebuilt linear solenoids sustain uniform hydraulic clamp under severe urban stop-and-go fleet transit.

Rigid die-cast A380 aluminum cases eliminate housing flex during sudden torque load transitions. Remanufactured valve bodies receive precision-machined Sonnax linear solenoid bore sleeves to eliminate internal line pressure drop. High-energy friction plates combine with surface-ground steel reaction plates to prevent clutch glaze. Casing specifications feature dual quick-connect cooler fittings, 8.5 quarts T-IV fluid capacity, and 184 lbs dry weight.

Key Features of GM AW5550SN

Fleet supervisors buy GM AW55-50SN remanufactured transmission packages to eliminate harsh shift flares across high-mileage utility crossovers. Rebuilt internal shift control components ensure predictable engagement under continuous municipal operations.

• Updated linear shift solenoids eliminate delayed forward gear engagement and slip flare
• Sonnax valve body bore sleeve inserts stop cross-circuit hydraulic pressure loss
• High-thermal carbon clutch frictions resist glazing under stop-and-go delivery operations
• Micro-finished GM AW5550SN planetary gear carriers minimize gear tooth whine
• Furnace-brazed torque converter impellers prevent internal blade separation at high speed
• High-volume internal oil pump bodies sustain 260 PSI pressure during continuous idle
• Bottom-pan magnetic collector points capture fine ferrous wear particles from fluid flow

Dynamic Fluid Thermal Ratings

Regulated internal fluid operating pressure spans 195 to 260 PSI across all forward gear selector ranges. Sump oil temperature balances between 165°F and 185°F under full thermal stabilization checks. Peak continuous input torque ratings reach 215 lb-ft at 3,800 RPM for municipal passenger fleets. Radiator tank cooler circuits dissipate 405 BTU per minute during heavy city operation. Forward gear ratios provide 4.77:1 first, 3.00:1 second, 1.96:1 third, 1.32:1 fourth, and 1.02:1 fifth gear reduction.

Drive Axle Spline Engagement

The unit features dual 24-spline differential side gears machined for direct mating to original equipment front drive axles. Structural differential gears hold 1,150 lb-ft static torque during sudden traction recovery events. Axle seal face runout measures within 0.0013 inches on precision dial indicators.

Adaptive Reset Service Directives

Installers must perform complete TCM fluid counter resets and adaptation drive cycles using diagnostic scan tools prior to customer handover. This transmission is not engineered for performance drag strip competition, vehicle curb-weight modifications, or pulling trailers exceeding factory vehicle tow limits.

• Examine cooler line quick-connect clips and wire harness seals every 50 hours
• Renew automatic transmission fluid and clean transmission case magnets every 30,000 miles
• Flush and refill full fluid capacity using approved T-IV fluid every 12 months

Warranty Statement Shipping Inventory

Commercial buyers receive an authorized 3-Year / 100,000-Mile commercial fleet warranty agreement. Secured inside an export wooden crate, the unit arrives with a remanufactured automatic transmission, precision-balanced torque converter, new cooler line retaining clips, and an inspection run sheet.
