4R70W 2001-2003 Ford E-Series, F-150 5.4L RWD – Remanufactured 4-Speed Automatic Trans

Description

Formulated for half-ton commercial trucks, the Ford F150 2002 Remanufactured Transmission provides exceptional mechanical stamina across punishing commercial routes. This 4-Speed 2WD platform supports 260 continuous horsepower and 350 lb-ft torque at a 5000 RPM maximum engine speed. Calibrated hydraulic circuits maintain 200 PSI mainline fluid pressure to prevent internal friction plate slip under gross vehicle cargo loads.

Enclosed in an A380 die-cast structural aluminum casing, this unit contains wide-ratio 8620 alloy steel planetary gearsets that stop tooth fracture under sudden load changes. Sintered bronze friction plates replace organic linings to resist high forward clutch heat. The remanufactured valve body includes hard-anodized aluminum bore sleeves plus an oversized steel pressure regulator spool. Total dry weight measures 205 lbs, holding 12 quarts of fluid through 3/8-inch inverted flare ports alongside a furnace-brazed lockup torque converter.

Key Features of Ford F150

Fleet operators choose to buy Ford F150 2002 remanufactured transmission inventory to maintain dependable work truck performance on job sites. This heavy driveline platform manages utility payload demands without gear hunting or hydraulic pressure drops.

• 4-Speed wide-ratio gearsets provide extra mechanical leverage during heavy cargo acceleration
• Remanufactured 2002 F150 valve body channels uniform line pressure without hydraulic bore wear
• 2 planetary gearsets disperse tooth contact pressure to resist fatigue fracture under load
• Precision balanced 2002 F150 torque converter package prevents harmonic vibration at highway cruise
• Upgraded Viton fluid seal rings maintain tight hydraulic clamping pressure under high heat
• High-capacity overdrive bands eliminate friction slide under continuous expressway pulling
• Calibrated accumulator springs soften shift engagement impact without extending friction slide

Torque Reduction Hydraulic Pressure Specs

Operating line pressures remain constant between 175 and 210 PSI across all forward speeds. Transmission sump temperatures hold steady from 165°F to 195°F when routed through external chassis fluid coolers. The internal geartrain delivers smooth step ratios consisting of 2.84:1 in 1st gear, 1.55:1 in 2nd gear, 1.00:1 in 3rd gear, and 0.70:1 in 4th gear overdrive. The complete rotating gear group sustains 350 lb-ft continuous input torque at 3000 RPM, channeling excess heat straight into external frame-mounted cooling coils without internal fluid breakdown.

Driveline Mount Spline Alignment

A precision-machined 28-spline output shaft interfaces straight with commercial slip yokes to drive rear differential axles. Front bell housing pilot register measures 5.000 inches to secure true concentric engine block mating. Distance from bell housing face to crossmember mount measures 24.8 inches, while total output bushing dial runout remains under 0.0016 inches.

Dynamometer Shakedown Scheduled Maintenance

Each completed unit undergoes full computer-controlled dynamometer runs under high payload resistance to verify shift solenoid actuation, mainline line pressure rise, and lockup clutch engagement. Automated fluid diagnostic sensors inspect cooler line flow rates and port pressures prior to crate shipping. This unit is not engineered for modified sled-pulling trucks, uncalibrated drag racing, or installations retaining contaminated transmission oil coolers.

• Inspect fluid level on level ground every 14 operating days
• Drain fluid and replace bottom pan filter every 25,000 miles
• Inspect transmission crossmember mount bolts every 12 months

Commercial Warranty Crate Package

Fleet buyers receive an extensive 3-Year unlimited mileage commercial warranty protecting transit investments against unexpected mechanical downtime on the job. The rugged wooden transport crate contains the complete remanufactured transmission, dyno-tested lockup torque converter, inline fluid filtration canister, vehicle installation guidelines, and fluid specification documentation tags.
