5R110W 2003-2007 Ford F-250/F-350 Super Duty RWD – Remanufactured 5-Speed Automatic Trans

Description

Engineered for high-payload commercial hauling, this Ford F-250 F-350 2003-2007 Remanufactured Transmission directs severe-duty gas and diesel output straight to the rear axle. The 5-Speed RWD platform supports 325 horsepower and 570 lb-ft of torque beneath a 4,200 RPM redline. Operating mainline hydraulic line pressure sustains 245 PSI to clamp internal friction plates tight during heavy towing.

A heavy cast aluminum casing encloses carburized 8620 steel helical gear sets and 3 planetary gearsets engineered for high shear resistance. Segmented graphite friction plates pair with thick nitrided steel reaction plates for optimal heat handling. The rebuilt valve body integrates wear-resistant bore sleeves and an oversized pressure regulator spool. Complete dry unit weight reaches 260 lbs, with an 18.0-quart fluid sump capacity and 1/2-inch inverted flare external oil lines.

Key Features of Ford F-250

Heavy hauling companies buy Ford F-250 F-350 2003-2007 remanufactured transmission units to cure torque converter clutch shudder and gear slipping in 3/4-ton and 1-ton trucks. Each rebuilt unit contains upgraded heavy-duty clutch packs engineered to cope with severe commercial towing demands.

• 31-spline turbine input shaft withstands high rotational twisting forces from heavy engines.
• F-250 F-350 2003-2007 replacement valve body prevents pressure drops in forward drive clutches.
• 5-Speed gear set provides effortless acceleration through a wide ratio spread ending in overdrive.
• Hardened steel planetary carriers handle massive torque without pin deflection or gear whine.
• 2003-2007 F-250 F-350 torque converter package utilizes furnace-brazed turbine fins for extra durability.
• Heavy-duty friction linings reject high heat buildup during heavy equipment transport runs.
• Upgraded electronic shift solenoids maintain precise gear transition timing in all driving modes.

Super Duty Towing Fluid Pressures

Internal line pressures cycle from 190 to 245 PSI through electronic pulse-width modulated solenoids. Operating fluid temperature hovers between 170°F and 195°F under continuous heavy towing cruise conditions. Gear reduction steps begin at 3.11:1 in 1st gear, progressing to direct 1.00:1 in 4th gear, and concluding at 0.71:1 in 5th gear overdrive. The high-capacity cooling circuit maintains fluid stability across demanding mountain passes.

Two Wheel Drive Yoke Centering

The transmission rear extension housing contains a 34-spline output shaft engineered to couple with heavy-duty driveshaft slip yokes. Tailshaft radial runout measures under 0.0016 inches on calibrated dial indicators. The structural crossmember mounting pad sits 29.8 inches back from the front bell housing face. A precision pilot register ensures centered alignment to eliminate driveline resonance throughout the vehicle cab.

TorqShift Bench Dyno Standards

Every gearbox runs on an automated load dynamometer using warm test oil to evaluate line pressure holding and clutch engagement times. This transmission is not engineered for competition sled pulling, oversized injector tuning, or vehicles retaining dirty transmission oil coolers.

• Examine fluid levels via the dipstick tube every 30 operating days.
• Drain fluid, clean magnetic pan, and replace external filter every 30,000 miles.
• Inspect transmission support crossmember bushings every 12 months.

Truck Crate Warranty Specifics

Each unit ships protected by a comprehensive 3-Year unlimited mileage warranty. The sealed wood crate contains the remanufactured 5-Speed transmission, dyno-verified torque converter, external fluid filter element, and fluid specification tags outlining OEM fluid requirements.
