6F50 2010-2012 Ford Taurus 3.5L FWD – Remanufactured 6-Speed Automatic Trans

Description

Adapted for coastal river skiffs, Ford 6F50 Taurus Marine Transmission remanufactured units equip 2010-2012 Ford Taurus 3.5L front-drive marine applications. This 6-speed automatic drivetrain manages 315 horsepower at a 6500 RPM input ceiling. Internal computer-actuated valves establish a 4.48:1 first gear reduction ratio to control vessel thrust in close-quarter docking maneuvers.

High-tensile gray iron casting walls reinforce the transmission housing against hull vibration and driveline twist. Precision-cut AGMA Class 11 helical gears mesh with crown relief to dampen operational drivetrain noise. Sintered bronze friction discs with cross-hatched fluid channels shed thermal loads from clutch packs. A cupronickel tube bundle heat exchanger with sacrificial zinc anode connects to 1.0-inch raw water pipes. Ports utilize 7/16-20 JIC flare fittings. Dry weight equals 224 lbs with 10.0 quarts capacity in an SAE #2 pattern.

Key Features of Ford 6F50

Commercial mariners choose to buy Ford 6F50 marine transmission units to modernize passenger ferries and harbor water taxis. This refined multi-speed gearbox improves cruising fuel economy while maintaining instant low-speed response for harbor maneuvers.

• 290 PSI line pressure circuits secure clutch pack lockup during sudden throttle advances
• 6 forward ratios provide a wide spread from a 4.48:1 first gear down to a 0.74:1 cruising gear
• 2.5 gallon per minute oil pumps circulate continuous transmission fluid through cooler circuits
• 12-volt pulse-width solenoids execute gear shifts within 80 milliseconds to minimize driveline interruption
• 4.48:1 planetary gear sets transmit high starting torque to rotate large diameter wheels
• 265 lb-ft torsional damper plates absorb engine pulses ahead of this 6F50 marine transmission unit
• 4 hole output companion flanges route shaft power straight to marine propeller shafts

Fluid Circuit Dynamic Thresholds

Working clutch fluid pressures operate within 220 to 290 PSI pump pressure to maintain clutch pack engagement across all throttle positions. Transmission sump fluid heat stays within 150°F to 185°F operating sump temperature throughout continuous runs. Peak continuous input torque measures 275 lb-ft at 4500 RPM under a medium duty rating. The cupronickel heat exchanger provides a thermal heat rejection rate of 615 BTU/min into raw water circuits. A 4.48:1 first gear mechanical reduction ratio directs high torque to propeller shafts for rapid hull planing.

Companion Flange Stern Alignment

The output companion flange features a 4.75-inch outer diameter and a 3.875-inch pitch circle diameter with 4 bolt holes. Heavy internal roller bearings absorb 2,150 pounds of continuous propeller thrust force. Flange vertical drop geometry spans 165 mm center distance. Dial indicator alignment runout to the stern tube shaft must remain below 0.003 inches.

Preventive Fluid Maintenance Matrix

Integrated electronic solenoids manage gear selection without mechanical push-pull cables, while an upper dipstick tube allows fast fluid level inspections. This transmission is not engineered for offshore fishing trawlers or heavy log-salvage tugboats. Strict adherence to fluid service intervals prevents clutch surface glazing during demanding vessel operations.

• Inspect fluid level and monitor fluid clarity at the dipstick each shift prior to dock departure
• Drain transmission fluid and service the internal pickup screen every 250 hours of continuous engine operation
• Inspect and replace sacrificial zinc anodes on the raw water cooler every 12 months during vessel drydock

Limited Warranty Crate Inventory

Every remanufactured unit includes a 2-Year commercial limited warranty protecting all internal gears and clutch packs from defects. The reinforced wood shipping crate contains one bare marine transmission unit, an input torsional flex plate, a seawater oil cooler bundle with mounting bracket, an output companion flange, an oil dipstick, and a factory workshop manual.
