AX4N 1994-1995 Ford Taurus, Mercury Sable 3.0L FWD – Remanufactured 4-Speed Automatic Trans

Description

Electro-hydraulic shift solenoids holding 215 PSI line pressure stabilize second-to-third gear transitions across congested urban taxi and courier schedules. The Ford AX4N Remanufactured Automatic Transmission fits 1994 to 1995 Ford Taurus and Mercury Sable 3.0-liter front-wheel platforms. Remanufactured valve bodies and reinforced drive chains prevent transmission slip under heavy passenger loads.

Die-cast A380 aluminum casing structures protect dual planetary gear sets and micro-finished sun shafts. Hard-anodized Sonnax sleeves restore worn valve body channels to stop fluid bypass. Featuring 3/8-inch inverted flare cooler connections, this 205-pound unit holds 12.2 quarts of fluid and attaches flush to vehicle chassis subframes without custom fabrication.

Key Features of Ford AX4N

Maintenance managers who buy Ford AX4N automatic transmission units obtain dyno-inspected powertrain systems built for continuous commercial duty. Each unit eliminates factory shift hunting by using upgraded hydraulic controls.

• Heavy carbon-metallic clutch frictions resist slippage and prevent heat glazing under elevated fluid temperatures
• Sonnax valve sleeves seal regulator circuits to maintain a constant 215 PSI hydraulic line pressure
• Linear electro-hydraulic shift solenoids react in 45 milliseconds for quick gear changes
• Dynamic balancer systems verify torque converter balance to within 0.04 gram-inches to stop vibration
• Case-hardened planetary pinion gears distribute tooth contact pressure during sudden acceleration
• Precision-ground steel reaction plates hold true flatness under severe friction clamp forces
• Remanufactured AX4N automatic transmission valve modules undergo strict vacuum decay tests on every port
• High-temperature fluoroelastomer casing gaskets stop fluid weeping around dynamic sealing joints

Hydraulic Line Pressure Dynamics

Line pressure operates across a controlled span from 60 PSI idle pressure up to 215 PSI under maximum engine load. Continuous input torque ratings handle 220 lb-ft at 4,000 RPM in severe commercial fleet service. Internal mechanical gear ratios offer 2.77:1 first, 1.54:1 second, 1.00:1 third, and 0.69:1 fourth overdrive. Auxiliary fluid coolers dissipate 19 kW of heat, holding operating temperatures between 165°F and 188°F.

CV Axle Spline Dimensions

The internal differential provides 28-spline output hubs that engage factory CV joint axle shafts without binding. The heavy-duty park pawl gear system withstands 1,450 lb-ft of holding torque on steep parking grades. Differential output runout tolerance measures under 0.0014 inches dial indicator runout, keeping vehicle propulsion steady across all speed ranges.

TCM Adaptive Relearn Sequence

Technicians must initiate diagnostic TCM adaptive shift programming after installation to ensure smooth clutch engagement profiles. This transmission unit is not engineered for competitive track racing, extreme vehicle speed runs, or towing trailers exceeding manufacturer gross vehicle weight ratings.

• Inspect fluid level and wipe metallic particles from the drain plug every 30,000 miles
• Drain fluid sump and add fresh synthetic transmission oil every 12 months
• Flush the transmission cooling circuit and inspect all line connections every 24 months

Commercial Warranty Crate Manifest

Supplied with a comprehensive 3-Year / 100,000-Mile commercial fleet warranty, this drivetrain delivers verified commercial durability. The heavy shipping box contains the remanufactured transmission unit, balanced torque converter, replacement cooler line crush washers, detailed installation manual, and dyno test printout.
