Ford F-250 HD F-350 Remanufactured Manual Transmission 11888T

Description

A 5.72 to 1 crawler first gear paired with 440 lb-ft input torque capacity moves heavy commercial equipment across steep construction grades using the Ford F-350 11888T Remanufactured Manual Transmission. This four-wheel-drive manual package delivers massive mechanical leverage for severe vocational fleet operations.

Housed in a reinforced cast aluminum case, this five-speed manual transmission integrates carbon-composite synchronizer friction cones with case-hardened 8620 steel shafts. Precision needle bearings reduce internal friction on third and fourth gear journals. Heavy-duty tapered roller bearings support the countershaft under continuous shock loads. Dual six-bolt power takeoff windows support external hydraulic apparatus. The bare gearbox weighs 178 lbs dry and holds 3.4 quarts of synthetic manual transmission lubricant.

Key Features of Ford 11888T

Professional repair facilities choose to buy Ford 11888T remanufactured transmission units to restore full powertrain reliability across municipal service fleets. Comprehensive rebuild procedures eliminate mechanical play to deliver consistent gear engagement under severe commercial duty cycles.

• 440 lb-ft input torque rating handles heavy fleet towing without gear tooth deflection
• 5 forward gear selections provide extreme reduction and efficient highway transport
• 0.76 to 1 overdrive gear ratio cuts engine cruising revolutions to conserve fuel
• 5.72 to 1 deep crawler first gear moves stalled equipment without clutch slip
• Wear-resistant bronze shift forks ensure crisp gear engagement under heavy use
• Micropolished mainshaft journals protect hydrodynamic bearing lubrication films
• Reinforced casing ribs resist bell housing flexing under dynamic torque transfers
• Six-bolt PTO side plates allow direct integration with hydraulic utility equipment

Powertrain Output Ratio Thresholds

Engineered for Severe Commercial Fleet demands, this manual transmission handles 440 lb-ft continuous input torque. Mechanical forward ratios span 5.72 to 1 in first, 2.94 to 1 in second, 1.61 to 1 in third, 1.00 to 1 direct fourth, and 0.76 to 1 in fifth overdrive. Reverse gear provides 5.24 to 1. External aluminum cooling ribs dissipate 460 BTU per minute under sustained vocational towing.

Transfer Case Coupling Specifications

The four-wheel-drive rear casing features a standard circular six-bolt mounting pattern designed for flush transfer case integration. The 31-spline output shaft exhibits dial runout under 0.0018 inches, preventing transfer case seal damage and vibration. Internal shift rail detents maintain firm gear engagement through severe chassis articulation over rough terrain.

Scheduled Shop Inspection Directives

Check clutch hydraulic master cylinder actuation and check bell housing mounting bolt torque during regular vehicle safety inspections. This transmission is not engineered for competition sled pulling or gross combined weights exceeding commercial vehicle rating plates.

• Check transmission oil fill level at the side port every 250 hours
• Drain transmission fluid and replace synthetic oil every 30,000 miles
• Inspect external shift boots for road debris tears each shift
