Ford F-150 F-250 F-350 Remanufactured Manual Transmission 11884T

Description

Adhere to strict commercial fleet maintenance benchmarks with 150 lbs of spin-bench tested drivetrain engineering that directs 470 lb-ft through synchronized forward gear steps in the Ford 11884T Remanufactured Manual Transmission engineered for Ford F-150, F-250, and F-350 super duty commercial trucks. This remanufactured heavy manual transmission provides high-torque multiplication and quiet highway cruising.

High-strength cast aluminum casing architectures resist case deflection under extreme driveline torque shock. Gear clusters feature 8620 carburized alloy steel with shot-peened gear root radii to distribute operational stress. Steel 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 150 lbs without oil, taking 3.6 quarts of approved synthetic manual gear oil.

Key Features of Ford 11884T

Commercial fleet managers choose to buy Ford 11884T manual transmission units to eliminate second-gear synchronizer grind in heavy trucks. Spin-test validation verifies quiet gear mesh and bearing preload prior to final crating.

• Shot-peened 8620 steel gear teeth resist tooth fractures during hard acceleration
• Sintered bronze synchronizers match countershaft speeds to stop gear clash
• 5 progressive forward gear steps balance aggressive climbing with relaxed highway cruise
• Ford 11884T 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 470 lb-ft continuous input torque at 2,800 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 highway 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 cable free play and pedal quadrant 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.
