2013 Nissan Altima 2.5L FWD – Remanufactured Automatic Trans

Description

Engineered for modern mid-size commuter routes, Nissan Altima 2013 Remanufactured Transmission units handle 2.5L QR25DE engine output in FWD sedan chassis. This remanufactured CVT automatic transaxle manages 182 continuous horsepower, 180 lb-ft maximum torque, and an engine ceiling of 6000 RPM while maintaining secondary pulley clamping hydraulic pressure of 850 PSI.

A high-pressure die-cast aluminum transaxle casing houses precision-ground primary and secondary variable diameter pulleys linked by a high-tensile steel push belt. The main hydraulic pump receives a hardened steel flow control valve with an anodized sleeve to prevent bore wear and pressure loss. Sump volume holds 8.6 quarts of Nissan NS-3 CVT fluid. Total dry transaxle weight measures 185 lbs, fitted with an integrated internal planetary reduction module and remanufactured torque converter.

Key Features of Nissan Altima

Fleet operators choose to buy Nissan Altima 2013 remanufactured transmission units to restore smooth acceleration and eliminate belt shudder in commercial commuter fleets. Comprehensive factory reconditioning replaces all critical drive belts and hydraulic control valves to guarantee continuous torque transfer under demanding urban driving conditions.

• High-tensile steel push belt with precision element bands eliminates belt slip across pulley sheaves.
• Hardened pump flow control valve and sleeve restore hydraulic line pressure to stop shudder.
• 8.6-quart fluid capacity stabilizes transaxle operating temperatures under continuous stop-and-go driving.
• 2013 Altima replacement valve body features calibrated linear solenoids to eliminate ratio shift delays.
• Altima 2013 torque converter package features upgraded friction linings to eliminate low-speed shudder.
• Stepless variable ratio spread spans 2.631:1 at launch down to a 0.378:1 overdrive highway ratio.
• 850 PSI secondary clamping pressure locks pulley sheaves fast to protect the steel drive belt.

CVT8 Pulley Ratio Thermal Management

A high-output internal gear pump maintains hydraulic clamping pressures between 150 and 850 PSI, keeping fluid sump temperatures within 165°F to 195°F. Input torque absorption handles 180 lb-ft at 4000 RPM without belt slippage. The stepless pulley ratio ranges from 2.631:1 at launch to 0.378:1 in overdrive, maintaining the 2.5L engine in its ideal fuel efficiency zone. An external transaxle cooler loop sheds excess heat through dedicated fluid lines, protecting pulley sheave surfaces and needle bearings from micro-pitting under sustained driving.

Front-Wheel Drive CV Axle Interface

Dual 27-spline differential output hubs link straight with factory front constant velocity axle shafts. Internal differential side gear backlash is held within 0.0025 inches on dial indicators, stopping front-wheel driveline vibration. Bell housing dowel sleeves align the transaxle case square against the engine block face, preserving input shaft centerlines under hard acceleration.

Dynamometer Spin Testing Maintenance Schedule

Every transaxle undergoes computerized dynamometer spin testing under simulated road load resistance to calibrate solenoid cycle rates, verify secondary clamping pressures, and evaluate forward clutch hold. This CVT transaxle is not engineered for nitrous-assisted street racing, aftermarket turbocharger additions, or operations using non-approved universal automatic transmission fluid without proper CVT ratings.

• Check transmission fluid level and deterioration counter data using scan tools every 30 operating days.
• Drain and refill approved Nissan NS-3 CVT synthetic fluid every 30,000 miles.
• Flush external transmission fluid cooler circuits every 12 months to prevent particulate blockage.

Transaxle Crate Manifest Warranty Inclusions

A 3-Year unlimited mileage warranty protects commercial fleet buyers against premature mechanical and hydraulic defects. Each sturdy wooden transport crate holds the complete remanufactured automatic transaxle, a balanced lockup torque converter, installation paperwork, cooler flushing guidelines, and fluid specification documentation tags specifying approved CVT fluid.
