A518 1993-1995 Dodge Ram Trucks & SUVs 5.9L RWD and AWD/4WD – Remanufactured 4-Speed Automatic Trans

Description

Locking internal clutch friction plates under 210 PSI pump force while managing 330 lb-ft torque, this Dodge Ram A518 Remanufactured Transmission restores smooth forward power for 1993 to 1995 Dodge Ram trucks and SUVs with 5.9L V8 engines. Fleet operators prevent driveline shudder during demanding regional towing runs without vehicle downtime.

Die-cast aluminum alloy housing walls eliminate casing twist under sudden acceleration demands. Precision CNC-machined valve bodies receive hard-anodized sleeves to halt fluid pressure drops within the primary clutch circuits. High-carbon friction plates feature curved oil channels to shed thermal buildup into 12.0 quarts of ATF+4 automatic transmission fluid. Dry weight checks in at 185 lbs with standard cooler fittings for fast cooling connection.

Key Features of Dodge Ram

Harsh second-to-third gear shift shock during heavy trailer towing leads fleet directors to buy Dodge Ram remanufactured transmission modules. Recalibrated hydraulic control packages deliver factory shift timing across high-mileage commercial service.

• A 2.45:1 first gear ratio multiplication delivers refined vehicle departure acceleration from stationary stops
• Hard-anodized valve bore sleeves eliminate internal cross-leaks to stabilize second-to-third gear transitions
• Radial fluid grooves cut into carbon friction plates accelerate heat dissipation under heavy stop-and-go runs
• Stress-relieved planetary gear carriers prevent pinion shaft looseness under high engine horsepower
• The Dodge Ram A518 system regulates pump line pressure between 120 and 210 PSI without hesitation
• Computer-balanced internal torque converters eliminate vibration through cabin footwells during highway travel
• Automated dyno hydro-pulse testing verifies overdrive solenoid response times within 12 milliseconds

Hydraulic Line Pressure Calibrations

Starting with a 2.45:1 low gear, this gear train steps through four mechanical ratios toward a 0.69:1 overdrive that keeps engine cruising speeds low. Operating clutch fluid circuits maintain 120 to 210 PSI pump force to clamp clutch packs without slip. Transmission fluid sump temperatures remain within an optimal 160°F to 190°F range on summer highways. Internal fluid pathways evacuate 860 BTU per minute of heat energy straight to the radiator cooler. Continuous input torque ratings sustain 330 lb-ft at 4,400 RPM without fatigue.

Driveline Output Spline Alignment

Transferring engine rotation straight through precision-ground splines, the output interface resists driveline lash. High-tensile alloy case construction prevents bearing pocket deformation during severe load changes. Internal parking pawl mechanisms hold 1,700 lb-ft of static rollback torque on 18-degree loading docks. Precision dial indicators measure total output hub runout under 0.0025 inches total indicator reading.

Control Module Adaptation Guidelines

Reset mechanical kickdown linkage positions and inspect overdrive cancellation switches before operating the vehicle in regular passenger 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 mechanical linkages to monitor throttle valve return tension and shift lever alignment
• Every 30 days check fluid level on level ground at 175°F using a calibrated workshop tool
• Every 30,000 miles drain contaminated ATF+4 fluid and replace pan filter elements to protect internal components

Commercial Fleet Crate Package

Fleet investments stay protected by an inclusive 3-Year / 100,000-Mile commercial fleet warranty covering parts plus labor nationwide. Each crated package ships with one remanufactured transmission, a dynamic-balanced torque converter, cooler port seal rings, setup instructions, plus dyno performance graphs.
