4R100 2000-2004 Ford F-250/F-350 Super Duty 6.8L RWD – Remanufactured 4-Speed Automatic Trans

Description

Constructed for continuous highway hauling, the Ford F350 Super Duty 2002 Remanufactured Transmission provides superior torque holding across demanding commercial transport applications. Built as a 4-Speed 2WD driveline, it handles 365 continuous horsepower and 430 lb-ft torque at engine speeds up to 5000 RPM. Calibrated hydraulic pressure circuits provide 205 PSI mainline force to stop clutch slip under maximum vehicle payload.

Enclosed in an A380 die-cast structural aluminum casing, this unit contains shot-peened 8620 alloy steel planetary gears that stop tooth shear during heavy vehicle acceleration. Sintered bronze friction plates replace organic linings to resist high intermediate clutch drum heat. The updated valve body features hard-anodized aluminum bore sleeves plus an oversized steel line pressure regulator valve. Total dry weight measures 270 lbs, holding 17.5 quarts of fluid through 1/2-inch inverted flare ports alongside a triple-disc lockup torque converter.

Key Features of Ford F350 Super Duty

Commercial contractors choose to buy Ford F350 Super Duty 2002 remanufactured transmission inventory to secure consistent powertrain uptime on long transit runs. This platform manages heavy utility trailer loads without loss of line pressure or thermal breakdown.

• 4-Speed steel forward clutch hubs eliminate spline strip under maximum cargo bed capacity
• Remanufactured 2002 F350 Super Duty valve body channels uniform line pressure without hydraulic bore wear
• 3 planetary gearsets disperse tooth contact pressure to resist shock fracture under load
• Precision balanced 2002 F350 Super Duty torque converter package prevents harmonic vibration at highway cruise
• Upgraded Viton fluid seal rings maintain tight hydraulic clamping pressure under high heat
• Hardened steel coast clutch drums eliminate ring groove blowouts under engine braking
• Heavy-duty intermediate mechanical diodes prevent roller rollover during aggressive 1st to 2nd gear shifts

Thermal Dynamics Gear Step Ratios

Operating line pressures remain constant between 190 and 230 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 2.71:1 in 1st gear, 1.54:1 in 2nd gear, 1.00:1 in 3rd gear, and 0.71:1 in 4th gear overdrive. The complete rotating gear group sustains 430 lb-ft continuous input torque at 3200 RPM, channeling excess heat straight into external frame-mounted cooling coils without internal fluid breakdown.

Driveline Mount Spline Alignment

A precision-machined 31-spline output shaft interfaces straight with commercial slip yokes to drive heavy rear axles. Front bell housing pilot register measures 5.400 inches to secure true concentric engine block mating. Distance from bell housing face to crossmember mount measures 26.8 inches, while total output bushing dial runout remains under 0.0016 inches.

Dynamometer Validation Maintenance Rules

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 Inventory

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.
