Ford F-250 F-350 Remanufactured Manual Transmission 11874T

Description

Sustain continuous 420 lb-ft driveline torque throughput and quiet gear mesh across demanding multi-stop municipal utility infrastructure construction corridors using the Ford 11874T Remanufactured Manual Transmission built for two-wheel drive Ford F-250 and F-350 gasoline trucks. This remanufactured heavy-duty manual gearbox delivers positive mechanical shift control without synchronizer clash.

High-pressure cast aluminum casing structures eliminate joint line distortion under high transfer case torque loads. Internal gear clusters incorporate 8620 carburized alloy steel with shot-peened gear root radii to distribute operational stress. Shift selector forks operate with hardened detent balls to secure each gear position. Sintered bronze synchronizer cones resist thermal degradation during rapid downshifts. Dry transmission weight equals 145 lbs without lubricant, taking 3.4 quarts of approved synthetic manual gear oil.

Key Features of Ford 11874T

Fleet maintenance directors choose to buy Ford 11874T remanufactured manual transmission units to eliminate gear popping and bearing hum in work vehicles. Dynamometer spin-stand testing proves quiet gear mesh and positive selector detents across every gear ratio.

• 8620 case-hardened steel gears withstand aggressive clutch dumps without tooth pitting
• Heavy-duty bronze synchronizer rings prevent gear grind during rapid upshifts
• 5 forward speed gear steps balance immediate throttle punch with relaxed cruising
• Ford 11874T rigid casing architecture stops case distortion during high torque transfers
• Polished selector rails ensure smooth mechanical movement between shifter gates
• Heavy duty mainshaft roller bearings eliminate shaft wobble and gear misalignment
• Micro-finished reverse idler gears maintain silent reverse gear engagement
• Viton input and output shaft oil seals provide long-term fluid retention

Mechanical Gear Ratios Capacity

Handling 420 lb-ft continuous input torque at 3,000 RPM, this manual gearbox satisfies high-stress commercial and private fleet demands. Operating gear oil temperatures maintain an optimal 150°F to 180°F profile through natural housing convection. Internal mechanical gear multiplication features a 5.72:1 first gear, 2.94:1 second gear, 1.61:1 third gear, 1.00:1 fourth gear direct link, and a 0.76:1 fifth gear overdrive ratio that reduces engine stress and fuel consumption on interstate corridors.

Chassis Output Spline Fitment

A 31-spline output shaft matches factory driveshaft slip yokes without looseness. Precision dowel pin holes align the bell housing face square to Ford truck engine blocks within 0.002-inch runout tolerance. The rear aluminum extension housing holds the driveshaft slip yoke steady under heavy torque loads.

Manual Transmission Maintenance Protocols

Clutch hydraulic release clearance and shifter linkage adjustment must be inspected before road use to guarantee full clutch disengagement. This unit is not engineered for track drag racing, extreme rock crawling, or gross combined vehicle weights exceeding factory chassis tow limits. Routine maintenance schedules protect synchronizer friction rings and bearing races from contamination.

• Inspect manual transmission gear oil level through the fill port each shift
• Drain and refill synthetic manual gearbox lubricant every 30,000 miles
• Check shifter boot seals and external mount hardware every 12 months

Warranty Terms Shipping Contents

A 3-Year / 100,000-Mile commercial fleet warranty protects all internal gears, shafts, and synchronizers from mechanical defects. The heavy-duty wooden shipping crate contains the remanufactured manual transmission unit, output slip protector, vehicle installation instructions, and an ATSG dyno spin-stand verification report.
