RE4R01A 2004 Nissan Xterra 3.3L RWD – Remanufactured 4-Speed Automatic Trans

Description

Propel loaded 3.3-liter commercial service trucks up steep rocky jobsite inclines under 202 lb-ft continuous torque without hydraulic pressure drop or gear slip through the Nissan Xterra 2WD RE4R01A Remanufactured Transmission built for 2004 Nissan Xterra two-wheel drive fleet utility trucks powered by 3.3L VG33E V6 gas engines.

A rugged die-cast aluminum housing integrates the bell housing and main transmission case, supporting heavy shot-peened planetary gear sets and high-capacity roller bearings. Multi-disc carbon-metallic clutch packs on forward speeds eliminate slip during aggressive throttle input. The unit weighs 175 lbs dry, holds 8.3 quarts of automatic fluid, and incorporates dual 3/8-inch fluid cooler connections.

Key Features of Nissan Xterra

Vocational utility contractors choose to buy Nissan Xterra automatic transmission gearboxes to stop intermediate shaft bearing rattle and restore crisp highway gear selection. Remanufacturing processes eliminate factory valve bore wear anomalies.

• 4-speed automatic gear configurations provide wide gear multiplication ranges for utility haul cycles.
• Hard-anodized valve body bore sleeves halt hydraulic fluid cross-leaks to maintain clutch clamp force.
• Induction-hardened reaction shells withstand severe engine torque without spline strip or shell shear.
• Dynamic multi-plate lockup clutch discs inside the remanufactured torque converter eliminate shudder.
• Nissan Xterra drivetrain solutions feature micro-polished seal journals to eliminate fluid leaks.
• High-integrity case perimeter sealant prevents fluid weepage under heavy torsional chassis flex.
• Magnetic fluid drain plugs attract ferrous debris to protect internal valve spools.

Dynamic Torque Transfer Gear Ratios

Rated for 202 lb-ft continuous input torque at 4,800 RPM, this transmission handles demanding commercial utility operations without internal clutch slippage. External case cooling fins dissipate hydraulic friction heat to hold sump temperatures below 185°F. Forward gear steps provide 2.78:1 first, 1.54:1 second, 1.00:1 third, and 0.69:1 fourth gear overdrive.

Transfer Case Output Interface Concentricity

The transmission output shaft features a 26-spline slip yoke interface machined to precise concentric tolerances. Driveshaft slip yoke journals maintain under 0.001-inch total radial runout to stop high-speed driveline vibration across rear universal joints. Front bell housing surfaces bolt flush to factory Nissan VG33E engine blocks using high-tensile alignment sleeves.

Shift Verification Fleet Maintenance Standards

Inspect cooler line flow volume and ensure correct throttle position switch voltage calibration before releasing the vehicle to service. This transmission is not engineered for drag strip launches, engine power outputs exceeding 260 horsepower, or towing commercial utility trailers exceeding 5,000 lbs.

• Check transmission fluid level using the hot dipstick method every 10,000 miles.
• Drain and replace internal transmission fluid using approved automatic lubricant every 30,000 miles.
• Inspect rear extension housing seals and crossmember mount cushions every 12 months.

Warranty Statement Logistics Crate Contents

Protected by a 3-Year / 100,000-Mile commercial warranty covering components and qualified technician labor. The heavy wooden transport crate contains the remanufactured four-speed automatic gearbox, balanced torque converter, cooler line sealing rings, setup instructions, and an inspector signed dyno verification log.
