FNR5 2006 Ford Fusion & Mercury Milan 2.3L FWD – Remanufactured 5-Speed Automatic Trans

Description

Across grueling twelve-hour municipal fleet logistics shifts demanding 180 stop-and-go curb drops, internal friction plates hold 270 PSI hydraulic clamp pressure without slip inside the Ford FNR5 Remanufactured Transmission built for 2006 Ford Fusion and Mercury Milan sedans powered by 2.3-liter four-cylinder engines. This remanufactured front-wheel drive transaxle restores clean gear changes and eliminates intermediate shift shudder.

High-integrity die-cast aluminum transaxle casings withstand torsional load transfers without housing cracking. The remanufactured valve body features hard-anodized valve bore sleeves and micro-honed spool bores to halt hydraulic fluid cross-leakage. Sintered bronze friction plates work with carbon-metallic clutches with radial heat dissipation grooves. Fluid passes through threaded 3/8-inch inverted flare cooler fittings linked to chassis coolers. Dry weight measures 178 lbs without torque converter, while fluid capacity requires 7.4 quarts of Mercon V fluid.

Key Features of Ford FNR5

Municipal fleet supervisors choose to buy Ford FNR5 remanufactured transmission units to restore positive shift control in high-mileage sedans. Extensive dyno cell load testing validates hydraulic line pressure regulation throughout every forward gear step.

• 270 PSI hydraulic circuit pressure eliminates clutch slipping under brisk acceleration
• 5 computer-controlled forward gear ratios optimize four-cylinder engine power and fuel economy
• Sonnax valve sleeves restore hydraulic seal integrity to stop shift flares
• Precision balanced torque converter prevents lockup clutch shudder during city driving
• Pulse-width modulated solenoids direct fluid volume for precise clutch engagement timing
• Ford FNR5 planetary gear sets undergo precision alignment to reduce operational noise
• High-output internal fluid pump channels continuous lubrication to all rotating parts
• Carbon-metallic friction discs resist thermal breakdown under sustained stop-and-go transit

Hydraulic Pressure Torque Ratings

Engineered to transfer 160 lb-ft continuous input torque at 4,250 RPM, this front-wheel drive transaxle provides dependable power delivery across severe commercial transit routes. Operating line pressures span 180 to 270 PSI to lock clutches securely during acceleration. Fluid sump temperatures stay regulated from 160°F to 185°F supported by a 35 kW external cooling loop. Mechanical gear steps feature a 3.66:1 first gear, 2.06:1 second gear, 1.38:1 third gear, 1.00:1 fourth gear, and a 0.73:1 fifth gear overdrive ratio.

Differential Spline Driveline Interface

Dual 28-spline differential outputs engage factory constant-velocity half-shafts with zero rotational play. Bell housing bolt patterns locate concentric to the 2.3-liter Duratec engine block within 0.003-inch runout tolerance. An internal parking pawl mechanism withstands 1,150 lb-ft holding force to anchor vehicles on steep hillsides.

Shift Adaptation Maintenance Schedule

Transmission control module adaptive relearn procedures calibrate shift solenoid timing over the initial 20 miles of vehicle operation. This unit is not engineered for track drag racing, extreme rock crawling, or gross combined vehicle weights exceeding factory chassis tow limits. Strict fluid service preserves internal friction life and prevents valve body varnish formation.

• Check automatic transmission fluid level and color each shift using the dipstick
• Drain and refill specified synthetic automatic transmission fluid every 30,000 miles
• Inspect external transmission cooler lines and rubber hoses every 12 months
