W5A580 2005-2010 Chrysler/Dodge 300, Challenger, Charger 5.7L RWD – Remanufactured 5-Speed Automatic Trans

Description

Torque converter friction plate shudder under 390 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 2005 to 2010 300, Challenger, and Charger 5.7-liter rear wheel drive sedans.

A380 aluminum transmission cases combine housing stiffness with rapid heat dissipation into underbody air streams. Hardened steel planetary gear sets pair with carbon-metallic friction discs featuring radial cooling grooves to withstand high-load highway acceleration. Hardware specs detail a furnace-brazed torque converter, 3/8-inch cooler fittings, 8.5-quart fluid sump capacity, and an overall dry unit weight of 185 lbs.

Key Features of Dodge W5A580

Municipal police departments buy Dodge W5A580 remanufactured transmission packages to lower operational fleet repair costs and maintain exceptional pursuit readiness. Rebuilt internal hydraulic valves ensure clean gear transitions through demanding high-speed pursuit maneuvers.

• Sonnax valve body bore sleeves halt hydraulic fluid bypass to preserve clutch clamp pressure
• Carbon-metallic friction plates resist heat buildup during long highway climbs
• Furnace-brazed torque converter impellers prevent vane flex under high stall loads
• Pulse-width modulated shift solenoids execute gear changes without driveline hesitation
• Dodge W5A580 transmission packages pass strict dial indicator runout and dyno load checks
• Nitrided planetary sun gear teeth prevent surface spalling under continuous vehicle operation
• Bottom-access steel fluid pans with magnetic drain plugs permit easy oil inspection

Rear Wheel Drive Pressure Levels

Engineered for commercial pursuit transport, this five-speed automatic transmission channels 390 lb-ft continuous input torque at 4,000 RPM under 170 to 225 PSI main line hydraulic pressure. Sump temperature runs between 160°F and 185°F under full-load routes. Forward ratios feature 3.595:1 first, 2.186:1 second, 1.405:1 third, 1.000:1 fourth, and 0.831:1 fifth overdrive, dissipating 56 BTU per minute through the cooling system.

Companion Flange Centerline Runout Limits

Rotational torque outputs through a heavy-duty three-arm companion flange designed to seat factory driveshaft flexible discs. Total dial indicator runout across output flanges holds under 0.0017 inches to stop driveline shudder. High-grade viton extension seals protect internal fluids from road water and grime.

Electro Hydraulic Conductor Plate Protocols

Conduct transmission computer adaptation relearn procedures following installation to ensure optimal shift timing. This automatic transmission is not engineered for heavy utility equipment hauling, off-road trials, or vehicle conversions exceeding manufacturer gross ratings.

• Check transmission dipstick fluid level and clarity each shift
• Flush transmission fluid and replace pan filter every 30,000 miles
• Inspect engine and transmission rubber mounts every 12 months

Commercial Drivetrain Protection Crate Inclusions

Covered by an outstanding 3-Year / 100,000-Mile commercial fleet warranty, this unit provides dependable long-term service. Shipment contains a fully remanufactured automatic transmission, balanced torque converter, cooler flush kit, and a certified dyno test report.
