RE4F04A 2002-2004 INFINITI I35, 2002-2003 Nissan Maxima 3.5L FWD – Remanufactured 4-Speed Automatic Trans

Description

Meet strict commercial executive fleet uptime standards with 210 lbs of dyno-tested drivetrain engineering that directs 255 horsepower through 4 computer-matched forward gear steps in the Nissan Maxima I35 RE4F04A Remanufactured Transmission engineered for 2002 to 2004 Infiniti I35 and 2002 to 2003 Nissan Maxima front-wheel drive sedans powered by 3.5L V6 engines.

The reinforced die-cast aluminum casing combines the bell housing and differential case, enclosing case-hardened planetary gear sets, carbon-metallic clutches, and heavy roller bearings. Valve bodies feature updated pressure regulator valve sleeves to secure positive gear engagement. The transaxle weighs 210 lbs dry, holds 8.8 quarts of automatic lubricant, and incorporates dual 3/8-inch fluid cooler connections.

Key Features of Nissan Maxima

Livery fleet procurement directors choose to buy Nissan Maxima automatic transmission assemblies to resolve first-to-second gear flares and stop torque converter shudder under heavy passenger workloads. Every transaxle receives complete teardown, casing ultrasonic cleaning, and precision valve body sleeve installation.

• 4-speed automatic gear ratios deliver broad torque multiplication to optimize 3.5L V6 power bands.
• Carbon-metallic clutch plates eliminate shift slipping between first, second, and third gears.
• Reinforced steel clutch hubs resist spline distortion under rapid commercial driver acceleration.
• Heavy-duty roller bearings stabilize differential carrier runout under continuous highway cruising.
• Nissan Maxima RE4F04A units incorporate updated linear solenoids to stop shift shudder.
• High-temperature Viton internal lip seals prevent hydraulic fluid bypass under severe operating conditions.
• Magnetic drain plugs capture ferrous metal particulate to protect internal valve spools.

Dynamic Torque Transfer Gear Ratios

Engineered to handle 246 lb-ft continuous input torque at 4,400 RPM, this automatic transaxle handles heavy commercial livery service without gear tooth micro-pitting. Structural casing walls keep transmission fluid sump temperatures below 185°F under full passenger load. Forward mechanical reduction ratios measure 2.78:1 first, 1.54:1 second, 1.00:1 third, and 0.69:1 fourth gear overdrive.

Output Shaft Spline Interface Yoke Dimensions

The transmission differential carrier incorporates 29-spline output pockets machined for exact engagement with factory front drive half-shafts. Concentric runout across the differential journals holds under 0.001 inches, preventing fluid leakage. Bell housing mounting faces bolt flush against Nissan VQ35DE engine blocks via precision alignment dowels.

Shift Calibration Protocol Service Limits

Verify transmission control module adaptation values and inspect cooler line flow rates prior to returning sedans to livery service. This transmission is not engineered for competitive track racing, turbocharger modifications exceeding 300 horsepower, or pulling trailers exceeding factory vehicle weight ratings.

• Inspect external fluid cooler lines and metal hose clamps every 15,000 miles.
• Drain and replenish transmission fluid using approved automatic transmission fluid every 30,000 miles.
• Inspect front CV axle boots and differential output seal cushions every 12 months.

Warranty Statement Heavy Crate Checklist

Covered by a 3-Year / 100,000-Mile commercial fleet warranty covering parts and authorized repair labor. The heavy-duty wooden shipping container contains the remanufactured four-speed automatic transmission, balanced torque converter, cooler line sealing rings, vehicle service instructions, and an inspector certified dyno test report.
