A518 1998-1999 Dodge Dakota, Durango 5.9L RWD – Remanufactured 4-Speed Automatic Trans

Description

Channeling 335 lb-ft of continuous input torque straight toward the rear drive axle under 210 PSI pump force, this Dodge Dakota Durango RWD Transmission resolves gear slip on 1998 to 1999 Dodge Dakota plus Durango 5.9L V8 rear-wheel-drive models. Fleet operators gain uninterrupted performance across demanding commercial delivery conditions without vehicle downtime.

High-tensile die-cast aluminum casting walls withstand driveline shudder along uneven road grades. Nitrided steel sun gear shafts mate with induction-hardened planetary carriers to eliminate gear tooth fracture risks under abrupt load spikes. Upgraded governor pressure sensor blocks prevent line fluid leakage across internal passages. Dry weight totals 185 lbs while housing 12.0 quarts of ATF+4 fluid plumbed through dual transmission oil cooler fittings.

Key Features of Dodge Dakota

Internal clutch slip during aggressive towing acceleration compels fleet managers to buy Dodge Dakota remanufactured transmission units. Factory-upgraded hydraulic valve bodies restore crisp gear transitions under demanding commercial hauling conditions.

• A 2.45:1 first gear ratio yields strong low-speed vehicle departure force under heavy cargo weight
• Nitrided planet gear teeth prevent fatigue pitting under continuous engine torque transfer cycles
• Dual-lip fluoroelastomer piston seals maintain hydraulic clamping pressure during extreme sub-zero weather
• Hardened steel clutch drums transfer engine power straight through planetary sets without distortion
• The Dodge Dakota 46RE platform delivers balanced oil feed to clutches under severe operating conditions
• Micro-honed valve bores fitted with hard-coat sleeves stop intermittent shift flare between gears
• Automated dyno diagnostics measure solenoid circuit resistance down to 0.1 ohm before final crating

Torque Management Fluid Dynamics

Four forward gear steps progress from a deep low gear up to a fuel-efficient 0.69:1 top overdrive ratio. Operating clutch fluid circuits generate 120 to 210 PSI line pressure to guarantee instant clutch plate clamping under full throttle. Sump fluid operating temperatures remain stabilized between 160°F and 190°F during intense highway operations. Transmission heat dissipation reaches 860 BTU per minute through high-volume external cooler circuits. Input torque capacity handles 335 lb-ft at 4,400 RPM across demanding fleet shuttle shifts.

Driveline Output Spline Alignment

Interfacing with the driveshaft slip yoke, the precision-machined output spline prevents driveline lash under rapid power transfers. Ductile iron case extensions withstand torque deflection during abrupt load shifts. The internal mechanical parking pawl resists 1,700 lb-ft of static holding torque on steep commercial grades. Output shaft axial runout checks confirm alignment under 0.0025 inches total indicator reading.

Electronic Solenoid Maintenance Standards

Execute complete TCM shift adaptation relearn routines before putting vehicles into commercial 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 transmission control module data streams to verify correct torque converter lockup slip rates
• Every 30 days check fluid color and saturation levels on level shop floors at operating temperature
• Every 30,000 miles drain sump fluid and clean pan magnets to prevent metallic debris from scoring valve bores

Nationwide Fleet Warranty Coverage

Commercial fleet operations receive complete coverage through our 3-Year / 100,000-Mile commercial fleet warranty on internal components. Crated shipments include one remanufactured transmission, an engine-balanced torque converter, replacement cooler connection o-rings, complete technical documentation, plus stamped dyno inspection charts.
