RE4R01A 2004 Nissan Xterra 3.3L AWD/4WD – Remanufactured 4-Speed Automatic Trans

Description

Die-cast A380 aluminum casing architecture absorbs severe driveline torque shock while carbon-metallic friction plates handle 202 lb-ft during grueling vocational work truck operation in the Nissan Xterra 4×4 RE4R01A Remanufactured Transmission engineered for 2004 Nissan Xterra four-wheel drive commercial utility platforms equipped with 3.3L VG33E V6 gas engines.

An extra-ribbed die-cast aluminum casing features heavy structural gussets, case-hardened planetary gear sets, and reconditioned valve body channels. Upgraded Sonnax valve sleeves handle the line pressure demands of severe duty off-road operation. The unit weighs 182 lbs dry, holds 8.3 quarts of automatic transmission fluid, and terminates in a round transfer case adapter.

Key Features of Nissan Xterra

Off-road commercial contractors choose to buy Nissan Xterra four-wheel drive automatic transmission packages to eliminate first gear hop-out and restore dependable torque transfer in severe jobsite conditions. Every unit undergoes precision bearing shimming and dynamic spin validation.

• 4-speed automatic gear architecture provides an effective 2.78:1 first gear for heavy jobsite crawler work.
• Carbon-metallic friction discs on forward speeds eliminate clutch slipping during rapid upshifts.
• Hard-anodized shift valve spools prevent pressure loss under severe engine vibration.
• Pre-shimmed bearing sets preserve exact shaft pre-load under full throttle.
• Nissan Xterra 4WD replacement transmissions incorporate updated heavy-duty brake band lining materials.
• High-grade fluoroelastomer input and output seals prevent gear fluid leaks under high sump heat.
• Magnetic drain plugs capture metallic friction particles to protect delicate valve components.

Operational Line Limits Torque Thresholds

Engineered to handle 202 lb-ft continuous input torque at 4,800 RPM, this automatic transmission handles heavy commercial utility service without gear tooth micro-pitting. Structural casing walls keep gear fluid sump temperatures below 185°F under full payload. 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 output shaft incorporates a 30-spline interface machined for exact engagement with factory transfer case input gears. Concentric runout across the adapter flange holds under 0.001 inches, preventing fluid leakage. Bell housing mounting faces bolt flush against Nissan 3.3L V6 engine blocks via precision alignment dowels.

Shift Calibration Protocol Service Limits

Verify line pressure at hydraulic test ports and inspect external transmission cooler flow prior to returning trucks to service. This transmission is not engineered for competitive racing, forced induction engine modifications, or pulling trailers exceeding factory vehicle weight ratings.

• Inspect external transmission cooler lines and hose clamps every 15,000 miles.
• Drain and replenish transmission fluid using approved automatic lubricant every 30,000 miles.
• Inspect transfer case adapter mounting bolts and crossmember mount cushions every 12 months.

Fleet Guarantee Secure Crate Contents
