The Continuously Variable Transmission (CVT) assembly with reference number 31020-3WX0E is designed for the Jatco JF017E (Nissan code RE0F10D). Engineered specifically for high-torque V6 applications like the 3.5L VQ35DE, this heavy-duty CVT features reinforced steel push-belts and an advanced hydraulic control system, delivering smooth, stepless acceleration for the Nissan Murano, Altima, Pathfinder, Quest, and related mid-size and full-size platforms.

Quick Specifications:

Part Number: 31020-3WX0E (Nissan OEM format)
Transmission Model: Jatco JF017E / Nissan RE0F10D
Type: Continuously Variable Transmission (CVT) - High Torque
Configuration: Front-Wheel Drive (FWD) / All-Wheel Drive (AWD) compatible
Max Input Torque: ~350-380 Nm (Optimized for 3.5L V6 engines)
Fluid Type: Nissan NS-3 CVT Fluid (NS-2 compatible for early 2009-2012 models)
Fluid Capacity: ~8.5 - 9.5 Liters (dry fill)

Applications:

Nissan Murano (Z51 / Z52, 2009-2020, 3.5L VQ35DE variants)
Nissan Altima (L33, 2013-2018, 3.5L V6 variants)
Nissan Pathfinder (R52, select 3.5L V6 CVT-equipped variants)
Nissan Quest (RE52, 2011-2017, 3.5L VQ35DE variants)
Nissan Maxima (A35 / A36, select 3.5L V6 variants)
Infiniti JX35 / QX60 (2013-present, 3.5L V6 variants sharing the RE0F10D platform)

Complete Assembly Includes:

✅ Heavy-duty transmission case with reinforced main bearing supports
✅ Extra-wide, high-tensile steel push-belt and enlarged primary/secondary pulleys
✅ Torque converter with heavy-duty lock-up clutch
✅ Advanced valve body with high-flow solenoids and step motors
✅ Integrated Transmission Control Module (TCM) or external connector
✅ High-capacity oil pump and input/output speed sensors
✅ Cooler lines, differential assembly (FWD/AWD specific), and sealing gaskets

Note: Transmission mounts, shift linkage, transfer case (for AWD models), and external wiring harness adapters may need to be transferred from the original unit.

Key Features:

✅ High-Torque Capacity: Specifically engineered with wider pulleys and a reinforced steel belt to handle the 350+ Nm torque of the VQ35DE V6 engine without slippage.
✅ Stepless Acceleration: Provides seamless power delivery, keeping the V6 engine in its optimal power and efficiency bands.
✅ Advanced Hydraulic Control: High-flow valve body ensures rapid clamping force adjustments during aggressive acceleration.
✅ AWD Compatibility: Includes provisions for the transfer case and rear driveshaft in AWD-equipped Murano and Pathfinder models.
✅ Thermal Management: Designed with optimized cooling passages to handle the higher heat generation of V6 powertrains.

Technical Notes:

Critical Installation Requirements:

Fluid Specification: Must use Nissan NS-3 CVT fluid (or NS-2 if specified for early 2009-2012 models). Using standard ATF or incorrect CVT fluid will cause immediate belt slippage and catastrophic failure.
Level Check Procedure: The fluid level must be checked via the overflow plug at a strict temperature range (typically 50°C–70°C) with the engine running and the fluid circulated through all modes.
TCM Calibration: After installation, a "TCM Memory Reset," "Idle Air Volume Learning," and "CVT Calibration" must be performed using a Nissan Consult-III or equivalent professional diagnostic scanner.
Cooler Flushing: The transmission cooler and lines must be flushed or replaced. Metal debris from a failed V6 CVT will destroy the new unit's valve body and pulleys immediately.

Common Issues & Maintenance:

Belt/Pulley Wear: While stronger than 4-cylinder CVTs, the JF017E can still suffer from belt slip if fluid degrades or if the vehicle is frequently used for heavy towing.
Overheating: V6 engines generate significant heat. Ensure the radiator and external CVT cooler are completely clean and functioning. Installing an auxiliary cooler is recommended for towing.
Valve Body Solenoids: Pressure control solenoids can wear out, leading to low line pressure and subsequent belt slip. Regular fluid changes prevent this.
Fluid Changes: Strict adherence to fluid change intervals (every 40,000–60,000 km) is critical for the longevity of the JF017E in heavy V6 applications.
