5R110W 2004-2008 Ford E-350/E-450/F-250 Super Duty 5.4L RWD – Remanufactured 5-Speed Automatic Trans

Description

Built for commercial van cutaways, this Ford E-350 Super Duty 2004-2008 Remanufactured Transmission transfers 5.4L Triton V8 power straight to the rear wheels. The 5-Speed RWD platform supports 255 horsepower and 350 lb-ft of torque beneath a 5,200 RPM limit. Internal mainline hydraulic fluid pressure regulates at 235 PSI to sustain stable clutch grip under heavy commercial payloads.

A thick cast aluminum case encloses carburized 8620 steel helical gear sets and 3 planetary gearsets designed to run quiet under load. Segmented graphite friction plates pair with nitrided steel reaction separator plates to prevent clutch glazing. The remanufactured valve body features hardened steel sleeves and an oversized mainline pressure regulator spool. Dry unit weight measures 258 lbs, supporting a 17.5-quart fluid capacity with 1/2-inch threaded inverted flare transmission cooler ports.

Key Features of Ford E-350

Fleet operators buy Ford E-350 Super Duty 2004-2008 remanufactured transmission inventory to resolve harsh shifting and clutch slippage on hard-working commercial transport vans. The precision remanufacturing process restores exact factory pressure control curves to match commercial workload profiles.

• 31-spline heat-treated input shaft handles abrupt torque loads from rapid pedal application.
• E-350 2004-2008 replacement valve body ends delayed reverse engagement and pressure loss.
• 5 forward gear ratios arrange smooth acceleration steps through an overdrive top gear.
• Upgraded clutch separator plates reject high heat during sustained high-speed highway transit.
• 2004-2008 E-350 torque converter package delivers rapid clutch lockup at highway cruising speeds.
• Hard-anodized internal accumulator pistons stop fluid pressure bypass during shift events.
• Precision roller sprag units guarantee immediate mechanical engagement under high vehicle momentum.

Triton Gas V8 Hydraulic Thresholds

Working line pressure maintains a strict 185 to 235 PSI operational band governed by the transmission control module. Operating fluid temperature remains regulated at 170°F to 195°F across high ambient temperature runs. Gear ratios begin with a wide 3.11:1 1st gear ratio, stepping down through a 1.00:1 4th gear, and concluding with a 0.71:1 5th gear overdrive. Continuous hydraulic circulation through the remote radiator heat exchanger preserves oil viscosity.

E-Series Slip Yoke Alignment

A precision-machined 34-spline rear output shaft links straight to the driveshaft slip yoke. Dial indicator runout testing checks output shaft center deflection under 0.0016 inches at the tail housing lip seal. The crossmember support pad sits 29.8 inches behind the bell housing mounting flange. Centering pilot register diameter ensures true axial driveline balance without balance runout vibrations.

Commercial Fleet Dyno Validation

Automated test benches run each rebuilt unit through simulated commercial payload profiles using heated transmission fluid to verify shift timings. This mechanical transmission is not engineered for nitrous oxide injection, drag racing slick tires, or chassis running crushed fluid lines.

• Check transmission oil fluid dipstick level every 30 operating days.
• Replace external fluid filter and synthetic ATF fluid every 30,000 miles.
• Inspect rubber transmission mount isolation blocks every 12 months.

Heavy Transport Warranty Manifest

Fleet purchases include a 3-Year unlimited mileage warranty safeguarding against mechanical fault. Each palletized shipping box includes the remanufactured 5-Speed transmission unit, precision balanced torque converter, external fluid filter, and synthetic lubricant fluid specification sheet.
