Ford F-250 HD F-350 Remanufactured Manual Transmission 11886T

Description

Eliminate gear tooth chipping and halt mainshaft deflection under 440 lb-ft sustained diesel torque output across rugged logging and construction corridors with the Ford F-250 HD 11886T Remanufactured Manual Transmission. This heavy duty four-wheel-drive unit provides maximum driveline strength for extreme fleet operations.

Built within a reinforced cast aluminum case, this five-speed manual transmission contains carbon-composite synchronizers and case-hardened alloy gear train components. Precision cylindrical roller bearings absorb extreme countershaft loads under continuous low-gear pulling. Induction-hardened steel shift rails prevent fork galling across heavy duty service intervals. Dual six-bolt PTO apertures permit direct hydraulic accessory drives. The bare transmission weighs 179 lbs dry and takes 3.4 quarts of synthetic manual transmission lubricant.

Key Features of Ford 11886T

Commercial fleet professionals buy Ford 11886T remanufactured transmission units to guarantee reliable drivetrain service under maximum gross vehicle payloads. Each remanufactured gearbox undergoes extensive spin testing to ensure precise gear tooth contact and silent mechanical operation.

• 440 lb-ft torque threshold handles severe diesel output without internal gear distortion
• 5 forward speeds deliver versatile mechanical advantage from crawl to highway transit
• 0.77 to 1 fifth gear overdrive lowers fuel usage on high-speed transport routes
• 4.14 to 1 first gear ratio provides smooth acceleration under maximum chassis payload
• Induction-hardened shift forks eliminate wear and maintain crisp shift lever feel
• Precision-ground synchronizer dogs ensure positive engagement without tooth grind
• Heavy-duty case ribs resist bell housing flexing under dynamic torque transfers
• Dual six-bolt PTO side plates drive hydraulic utility winches and dump bed hoists

Torsional Ratio Kinetic Parameters

Engineered for Severe Commercial Fleet duty, this manual transmission handles 440 lb-ft continuous input torque at 2,800 RPM. Forward mechanical ratios provide 4.14 to 1 in first, 2.37 to 1 in second, 1.42 to 1 in third, 1.00 to 1 direct fourth, and 0.77 to 1 fifth overdrive. Reverse operates at 3.79 to 1. The aluminum casing radiates 475 BTU per minute under heavy hauling conditions.

Four-Wheel Drive Mating Interface

The rear housing features a circular six-bolt bolt circle pattern that connects flush to the transfer case input adapter. A hardened 31-spline output shaft exhibits dial runout under 0.0018 inches to prevent transfer case seal damage. Mechanical shift gate interlocks eliminate the danger of gear jump-out during severe chassis articulation on rough terrain.

Preventative Fleet Maintenance Directives

Inspect clutch hydraulic slave cylinder actuation and check bell housing mounting bolt torque during regular vehicle safety inspections. This transmission is not engineered for competitive off-road sled pulling or vehicle loads exceeding legal axle gross ratings.

• Check gear oil level through the inspection hole every 250 hours
• Drain transmission fluid and replenish synthetic oil every 30,000 miles
• Inspect transmission rubber crossmember isolators each shift

Crate Shipment Manifest Terms

Guaranteed by an extensive 5-Year / 100,000-Mile fleet warranty, this unit ships secured inside a reinforced wooden shipping crate. Package contents include the fully remanufactured manual transmission, pre-cut top cover gasket, reverse light indicator switch, and complete dyno performance verification documentation.
