CD4E 2001-2002 Mercury Cougar 2.5L FWD – Remanufactured 4-Speed Automatic Trans

Description

Downshifting into sweeping highway curves near 5,500 RPM requires crisp 40-millisecond solenoid reactions and 185 PSI line pressure to prevent ratio slip. The Mercury Cougar CD4E Remanufactured Transmission powers final-generation 2001 to 2002 Mercury Cougar 2.5-liter front-wheel sport coupes. Upgraded friction materials and re-sleeved valve bodies eliminate converter shudder during aggressive highway maneuvers across uninterrupted driving shifts.

Die-cast A380 aluminum casing structures protect dual planetary gear sets, hardened friction drums, and wide steel drive bands. Upgraded stamped steel forward clutch drums replace crack-prone cast units to halt internal pressure loss. Outfitted with 5/16-inch inverted flare cooler ports, this 165-pound four-speed unit holds 8.5 quarts of Mercon V fluid and mounts flush to factory engine cradles.

Key Features of Mercury Cougar CD4E

Performance repair centers that buy Mercury Cougar CD4E automatic transmission packages acquire dyno-tested hardware configured for high-output V6 engines. Advanced fluid circuit engineering guarantees sustained hydraulic pressure during high-rpm gear changes.

• Upgraded stamped steel forward clutch cylinders eliminate catastrophic drum cracking under continuous load
• Sonnax hard-anodized pressure regulator valve sleeves maintain steady 185 PSI hydraulic main pressure
• High-energy carbon-composite 2-4 bands prevent intermediate ratio slippage during wide-open throttle
• Dynamic computer balancing trims torque converter unbalance down below 0.04 gram-inches to stop vibration
• Carburized planetary gears distribute tooth contact pressure during rapid stop-and-go driving cycles
• Precision-ground steel reaction plates resist heat warping under elevated operating temperatures
• Remanufactured CD4E transaxle valve bodies pass multi-stage vacuum integrity testing on each port
• Heavy-duty fluoroelastomer drive axle seals prevent fluid weeping past differential output collars

Hydraulic Operating Pressure Range

Operating line pressures span from 60 PSI idle pressure up to 185 PSI under maximum engine acceleration. Continuous input torque ratings handle 170 lb-ft at 4,250 RPM in severe commercial fleet service. Internal mechanical gear ratios offer 2.88:1 first, 1.57:1 second, 1.00:1 third direct, and 0.69:1 fourth overdrive. Auxiliary fluid coolers dissipate 17 kW of heat, holding operating temperatures between 165°F and 188°F.

Differential Axle Spline Interface

Equalized internal differential outputs accept 26-spline front half-shaft CV joints without mechanical play. The reinforced park pawl mechanism holds 1,350 lb-ft of static driveline load on inclined parking ramps. Differential output hub runout measures under 0.0013 inches dial indicator deflection, maintaining steady front-wheel rotation at sustained highway speeds.

Electronic Shift Solenoid Adaptation

Technicians must clear PCM shift adaptation memory and verify manual selector cable alignment after installation to prevent clutch slip. This transmission unit is not engineered for competitive track drag racing, extreme vehicle speed trials, or gross vehicle weights exceeding factory chassis ratings.

• Check transmission fluid clarity and examine pan magnet cleanliness every 30,000 miles
• Drain fluid sump and replenish with approved synthetic oil every 12 months
• Flush external transmission cooler lines and clean heat exchanger fins every 24 months

Standard Warranty Crate Contents

Every unit includes a 3-Year / 100,000-Mile commercial fleet warranty for lasting vehicle protection. The protective shipping container carries the fully remanufactured transmission unit, balanced torque converter, replacement cooler line washers, installation instructional sheet, and signed dynamometer test results.
