Ford F-250 F-350 Remanufactured Manual Transmission 11876T

Description

Halt gear clash and eliminate synchronizer drag under 420 lb-ft input force across extreme vocational job sites with the Ford F-250 11876T Remanufactured Manual Transmission. Engineered for 4WD truck platforms, this unit restores positive shift engagement while supporting demanding chassis configurations throughout severe towing operations.

Built inside a cast aluminum case, this five-speed unit features molybdenum-coated synchronizer rings and case-hardened 8620 steel helical cut gear sets. Needle roller bearings support each mainshaft journal to minimize friction under maximum torque. Tapered roller countershaft bearings handle continuous radial loads. Dual side power takeoff access ports permit external pump integration. The bare dry casing weighs 175 lbs and holds 3.4 quarts of synthetic manual transmission fluid.

Key Features of Ford 11876T

Fleet operators looking to buy Ford 11876T remanufactured transmission units gain verified drivetrain durability for demanding commercial hauling. Each remanufactured unit undergoes strict gear tooth mesh inspection to sustain high powertrain up-time under severe duty cycles.

• 420 lb-ft input torque rating handles heavy fleet towing without gear deflection
• 5 forward speeds provide optimal gear multiplication across severe vocational terrain
• 0.76 to 1 overdrive gear ratio cuts engine cruise RPM on open highways
• 5.72 to 1 granny low first gear pulls loaded trailers up steep commercial ramps
• Cast bronze shift forks with induction hardened tips resist mechanical wear
• Pre-set countershaft bearing preload eliminates mainshaft end-play under severe load
• Billet steel shift rails prevent internal cross-pin binding during fast gear changes
• Standard six-bolt PTO aperture supports external hydraulic winch integration

Mechanical Torque Transfer Ratios

Engineered for Severe Commercial Fleet operations, this five-speed manual transmission channels 420 lb-ft continuous torque without gear tooth deflection. The gear 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 drive in fourth, and 0.76 to 1 in fifth overdrive. Reverse operates at 5.24 to 1. An external aluminum finned casing sheds 450 BTU per minute of heat during sustained mountain transit.

Transfer Case Flange Specifications

The tailhousing connects straight to four-wheel-drive transfer cases using a standard six-bolt circular pattern. A 31-spline output shaft delivers zero-backlash power transfer to the transfer case input gear. Mainshaft runout tolerance measures under 0.002 inches on dial indicators. The internal mechanical shift detents lock gear selectors against gear jump-out on rough terrain.

Fleet Service Operational Procedures

Inspect gear shift lever bushings and clutch linkage rod adjustment during scheduled fleet servicing. This transmission is not engineered for passenger track drag racing or gross vehicle loads exceeding factory axle gross weight ratings.

• Inspect fluid level through the side fill plug every 250 hours
• Drain and refill synthetic manual gear oil every 30,000 miles
• Check shifter ball socket retaining pin wear each shift

Commercial Crate Delivery Manifest

Backed by a standard 3-Year / 100,000-Mile commercial fleet warranty, this unit ships secured in an impact-resistant transit crate. Package includes the fully remanufactured transmission gearbox, pre-installed shift tower gasket, backup light switch, and dynamometer spin test documentation.
