The Continuously Variable Transmission (CVT) assembly with reference number 3102050X0A is designed for the Jatco JF020E (Nissan code RE0F10F). Part of Nissan's advanced CVT8 (Xtronic) family, this next-generation unit features a wider gear ratio spread and reduced internal friction, delivering smoother acceleration and superior fuel efficiency for the Nissan Altima, Rogue, X-Trail, and related mid-size platforms.

Quick Specifications:

Part Number: 3102050X0A (Nissan OEM format)
Transmission Model: Jatco JF020E / Nissan RE0F10F (CVT8 Generation)
Type: Continuously Variable Transmission (CVT)
Configuration: Front-Wheel Drive (FWD) / All-Wheel Drive (AWD) compatible
Max Input Torque: ~250-380 Nm (Optimized for 2.0L, 2.5L, and select 3.5L engines)
Fluid Type: Nissan NS-3 CVT Fluid
Fluid Capacity: ~7.5 - 8.5 Liters (dry fill)

Applications:

Nissan Altima (L33) (2013-2018, 2.5L QR25DE variants)
Nissan Rogue (T32) (2014-2020, 2.5L variants)
Nissan X-Trail (T32) (2014-2020, 2.0L/2.5L variants)
Nissan Murano (Z52) (Select 3.5L V6 and Hybrid variants)
Nissan Maxima (A36) (Select 3.5L variants)
Infiniti QX60 / JX35 (Select 3.5L variants sharing the CVT8 platform)

Complete Assembly Includes:

✅ Transmission case with high-ratio spread primary and secondary pulleys
✅ High-tensile steel push-belt
✅ Torque converter with early-engagement lock-up clutch
✅ Advanced valve body with high-response solenoids and step motors
✅ Integrated Transmission Control Module (TCM) or external connector
✅ High-capacity oil pump, speed sensors, and differential assembly (FWD/AWD specific)

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:

✅ Wider Ratio Spread: Achieves a massive 7.0:1 gear ratio spread (comparable to a 7-speed automatic) for aggressive off-the-line acceleration and relaxed, low-RPM highway cruising.
✅ Reduced Friction: Internal friction reduced by up to 40% compared to previous CVT generations, significantly boosting overall vehicle fuel economy.
✅ Faster Response: Improved hydraulic control and early lock-up clutch operation provide a more direct, stepped-gear feel during hard acceleration, minimizing the traditional "CVT drone."
✅ Compact & Lightweight: Optimized internal packaging reduces overall transmission weight and improves vehicle payload capacity.

Technical Notes:

Critical Installation Requirements:

Fluid Specification: Must use Nissan NS-3 CVT fluid exclusively. Using older NS-2 fluid or standard ATF will cause immediate belt slippage, overheating, and catastrophic failure due to incorrect friction modifiers and viscosity.
Level Check Procedure: The fluid level must be checked via the overflow plug at a strict temperature range (typically 40°C for the initial check, then 50°C–70°C for the final check) with the engine running and the fluid circulated.
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. Metallic debris from a failed CVT will clog the new valve body and destroy the pulleys immediately.

Common Issues & Maintenance:

Valve Body/Solenoid Wear: Fine clutch material or metal debris can clog the precision solenoids, causing low line pressure and subsequent belt slip. Regular fluid changes are the best prevention.
Overheating: Ensure the radiator and external CVT cooler are completely clean. Towing or aggressive driving without an auxiliary cooler can degrade NS-3 fluid rapidly.
Fluid Changes: Strict adherence to NS-3 fluid change intervals (every 40,000–60,000 km) is absolutely critical for the longevity of the JF020E push-belt and pulley surfaces.
