RE5R05A 2005 Nissan Armada 5.6L AWD/4WD – Remanufactured 5-Speed Automatic Trans

Description

Prevent direct clutch drum scoring under 385 lb-ft sustained engine output while maintaining 185°F fluid sump stability during demanding high-idle municipal emergency response operations using the Nissan Armada 4WD RE5R05A Remanufactured Transmission configured for 2005 Nissan Armada four-wheel drive commercial fleet sport utility vehicles powered by 5.6L V8 gas engines.

An ultra-rigid cast aluminum main case encloses shot-peened helical gear sets, multi-plate carbon clutches, and high-capacity tapered roller bearings. Shift rails feature updated detent pockets to secure positive gear engagement under extreme chassis torsional stress. The unit weighs 215 lbs dry, holds 11.2 quarts of automatic lubricant, and incorporates a round transfer case tailhousing adapter.

Key Features of Nissan Armada

Off-road utility contractors choose to buy Nissan Armada 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.

• 5-speed automatic gear architecture provides an effective 3.84:1 first gear for heavy jobsite crawler work.
• Carbon-composite 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 Armada 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.

Dynamic Torque Transfer Gear Ratios

Designed to manage 385 lb-ft continuous input torque at 3,600 RPM, this automatic transmission handles spirited commercial transit without internal clutch fatigue. Casing heat dissipation holds synthetic fluid sump temperatures below 185°F during heavy work cycles. Internal gear ratios measure 3.84:1 first, 2.35:1 second, 1.53:1 third, 1.00:1 fourth, and 0.83:1 fifth gear overdrive.

Transfer Case Output Interface Concentricity

The transmission output shaft utilizes a 32-spline profile designed for direct connection with factory transfer case input gears. Concentric runout across the adapter flange holds within 0.001 inches, halting fluid weepage between housings. The front face bolts flush to Nissan engine blocks using standard dowel pin locations.

Pre-Service Inspection Operational Boundaries

Inspect the torque converter drive plate friction face and verify pilot hub depth prior to transmission installation. This automatic gearbox is not engineered for mud bogging competitions, engine swaps exceeding 420 horsepower, or towing trailers exceeding manufacturer gross ratings.

• Inspect transfer case shift linkage bushings and rubber pivot grommets every 15,000 miles.
• Drain and refill transmission fluid using approved automatic lubricant every 30,000 miles.
• Verify transfer case adapter mounting bolts and crossmember isolator tightness every 12 months.

Warranty Statement Heavy Crate Checklist

Covered by a 3-Year / 100,000-Mile commercial warranty covering parts and authorized repair labor. The reinforced wooden transport crate contains the remanufactured five-speed automatic transmission, balanced torque converter, transfer case adapter gasket, vehicle service instructions, and an inspector signed dyno verification log.
