4AT-SUBARU 2004 Subaru Forester 2.5L AWD/4WD – Remanufactured Automatic Trans

Description

Formulated for utility crossover platforms, Subaru Forester 2004 Remanufactured Transmission supports the 2.5L engine package with 165 continuous horsepower and 166 lb-ft peak torque. Operating beneath a 6,000 engine RPM ceiling, the unit commands 155 PSI line pressure, delivering balanced power through this proven 4-Speed AWD layout without power interruption.

Die-cast A380 aluminum casing structures enclose carburized helical gears paired with high-energy friction discs. The updated hydraulic valve body integrates hard-anodized sleeves and replacement solenoids that eliminate hydraulic line pressure drops. Precision 3/8-inch cooler ports service a 173 lbs dry transaxle holding 9.5 quarts of fluid with an integrated front hypoid differential and lockup converter.

Key Features of Subaru Forester

Fleet automotive buyers buy Subaru Forester 2004 remanufactured transmission units to restore factory driveline integrity on commercial transport vehicles. The engineered components maintain shift stability across changing seasonal weather patterns and steep grades.

• 4-Speed AWD planetary gear units distribute power between front and rear axles under all conditions
• Reinforced multi-plate transfer clutch packs balance power distribution without driveline chatter
• 2004 Forester replacement valve body upgrades eliminate shift flare between 1st gear and 2nd gear
• Hardened front pinion shafts sustain constant differential gear mesh under heavy load
• Forester 2004 torque converter package features balanced lockup plates that prevent cruise vibration
• Teflon-coated oil pump bushings lower drag and resist galling under high-RPM operation
• Thicker friction plates expand thermal saturation capacity during extended highway transit

Operating Hydraulic Pressures Gear Spread Limits

Internal mainline pressure operates from 145 to 190 PSI during wide-open throttle application cycles. Fluid sump operating temperature stays between 165°F to 195°F during extended continuous highway transit. Built to manage 166 lb-ft input torque at 4,000 RPM, mechanical gear steps span a 2.785:1 1st gear, 1.545:1 2nd gear, 1.000:1 3rd gear, out to a 0.694:1 overdrive. Dedicated fluid circuits shed core heat before excessive thermal soak occurs.

Output Shaft Coupling Center Specifications

Dual 25-spline differential stub outputs accept stock front drive half-shafts without modification. Distance from the engine bell face to rear companion flange measures 29.35 inches. Lower chassis mounting pads align with vehicle subframes, with center output runout constrained below 0.0018 inches for smooth driveline operation.

Automated Bench Shift Dyno Screening

Electronic valve testers monitor PWM solenoid performance on a hot-oil dynamometer replicating diverse road gradients. This driveline is not engineered for pro-mod drag racing, competition sled-pulling trucks running uncalibrated tuning, or drivelines with contaminated fluid coolers.

• Inspect fluid level on level ground every 14 operating days
• Renew transmission fluid and spin-on filter every 25,000 miles
• Check external cooler lines and clamps every 12 months

Fleet Warranty Delivery Crate Manifest

Every commercial purchase provides a 3-Year unlimited mileage warranty. Secure crating holds the complete remanufactured transmission, a dynamic balanced torque converter, an inline fluid filter, an installation manual, and factory-certified fluid specification charts.
