W5A580 2012-2013 Dodge Durango & Jeep Grand Cherokee 3.6L RWD – Remanufactured 5-Speed Automatic Trans

Description

Torque converter friction plate shudder under 260 lb-ft hauling loads compromises municipal fleet response deadlines until hydro-pulse calibrated solenoids and upgraded friction plates stabilize internal fluid circuits inside the Dodge W5A580 Remanufactured Transmission engineered for 2012 to 2013 Durango and Grand Cherokee 3.6-liter rear wheel drive utility platforms.

Die-cast A380 aluminum transmission casings house high-precision planetary gear carriers and micro-polished hydraulic separator plates. Upgraded valve body bores feature hard-anodized sleeves to halt hydraulic pressure drop under high operating temperatures. Driveline utility hardware includes a rear three-arm companion flange, 3/8-inch inverted flare cooler line ports, 8.5-quart fluid capacity for genuine ATF+4 fluid, and a 185-pound dry unit mass.

Key Features of Dodge W5A580

Field service teams buy Dodge W5A580 remanufactured transmission units to restore work vehicle mobility and eliminate gear hunting on steep highway grades. Every internal hydraulic circuit undergoes hydro-pulse dyno testing to verify correct shift timing across all engine loads.

• Hard-anodized valve body bore sleeves prevent internal hydraulic circuit pressure leakage
• High-energy carbon-metallic clutch plates withstand continuous high-speed transit shifts without glazing
• Precision balanced furnace-brazed torque converters eliminate high-speed driveline vibration
• Pulse-width modulated solenoids respond to TCM commands within 40 milliseconds for crisp gear shifts
• Dodge W5A580 automatic transmissions undergo full hydro-pulse dyno cell load testing before crating
• Micro-finished planetary gear tooth profiles keep transmission operating noise to absolute minimums
• Magnetic fluid pan collectors trap microscopic steel particulate to extend hydraulic valve life

Dynamic Torque Transmission Pressure Bounds

Built for demanding utility fleet transit, this five-speed automatic transmission manages 260 lb-ft continuous input torque at 4,800 RPM under 165 to 220 PSI main line circuit pressure. Sump temperature holds between 160°F and 185°F under full thermal stabilization. Gear reduction ratios deliver 3.595:1 first, 2.186:1 second, 1.405:1 third, 1.000:1 fourth, and 0.831:1 fifth overdrive, releasing 50 BTU per minute across auxiliary cooler circuits.

Rear Driveshaft Slip Yoke Standard

Power transfers straight through a precision-machined three-arm companion flange bolted to the output shaft to seat factory rubber guibo couplers. Output journal centerline runout measures under 0.0016 inches across all rotational test points. Precision machined rear extension housing seals prevent fluid weeping during high-speed driving.

Automatic Transmission Fluid Sump Protocols

Verify that transmission cooler lines remain free of internal sludge to preserve transmission fluid cooling flow. This automatic transmission is not engineered for competition drag racing, high-boost engine tuning, or towing trailers exceeding factory vehicle gross weight limits.

• Inspect cooler line connections and casing pan seams each shift
• Drain and refill with approved ATF+4 fluid every 30,000 miles
• Inspect electronic wiring harness connectors for corrosion every 12 months

Commercial Warranty Package Shipment Details
