The Continuously Variable Transmission (CVT) assembly with reference numbers 5189839AA (Chrysler/Jeep) and 31020-1XT9A (Nissan) is designed for the Jatco JF011E (Nissan code RE0F10A). This 4WD/AWD variant features an integrated Power Take-Off (PTO) transfer case, reinforced steel push-belts, and advanced hydraulic control, delivering smooth, stepless acceleration and all-weather traction for the Nissan X-Trail, Qashqai, Jeep Compass, and Patriot.

Quick Specifications:

Part Numbers: 5189839AA / 31020-1XT9A (Chrysler/Nissan OEM format)
Transmission Model: Jatco JF011E / RE0F10A (4WD/AWD)
Type: Continuously Variable Transmission (CVT) with Transfer Case
Configuration: All-Wheel Drive (AWD) / 4WD
Max Input Torque: ~250 Nm (Optimized for 2.0L, 2.4L, and 2.5L engines)
Fluid Type: Nissan NS-2 / Mopar CVTF+4
Fluid Capacity: ~8.0 - 9.0 Liters (dry fill, including transfer case)

Applications:

Nissan X-Trail (T31) (2007-2014, 2.0L/2.5L 4WD variants)
Nissan Qashqai / Dualis (J10) (2007-2014, 2.0L 4WD variants)
Nissan Rogue (T35) (First Generation, 2.5L AWD variants)
Jeep Compass (MK) (2007-2017, 2.0L/2.4L 4WD variants)
Jeep Patriot (MK) (2007-2017, 2.0L/2.4L 4WD variants)
Dodge Caliber (Select 2.4L AWD variants)
Mitsubishi Outlander (Select 2.4L 4WD variants sharing JF011E)

Complete Assembly Includes:

✅ Transmission case with dual pulley system (Primary & Secondary)
✅ High-strength steel push-belt
✅ Torque converter with lock-up clutch
✅ Valve body with step motors and pressure control solenoids
✅ Integrated Power Take-Off (PTO) / Transfer case for rear driveshaft
✅ Oil pump, input/output speed sensors, and differential assembly
✅ Cooler lines and sealing gaskets

Key Features:

✅ AWD/4WD Capability: Integrated rear PTO seamlessly distributes torque to the rear wheels via the rear driveshaft for enhanced traction in snow, mud, and light off-road conditions.
✅ Stepless Acceleration: Provides smooth, uninterrupted power delivery, keeping the engine in its optimal efficiency band.
✅ High-Tensile Push-Belt: Engineered to handle the torque of 2.0L to 2.5L 4-cylinder engines without slippage.
✅ Adaptive Logic: Adjusts pulley ratios and clutch engagement based on throttle input, vehicle load, and road conditions.
✅ Cross-Platform Compatibility: Shared architecture between Renault-Nissan and Chrysler/Jeep, making it a highly serviceable unit globally.

Technical Notes:

Critical Installation Requirements:

Fluid Specification: Must use Nissan NS-2 or Mopar CVTF+4 fluid exclusively. These fluids share the same friction specification. Using NS-3, 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.
TCM Calibration: After installation, a "TCM Memory Reset" and "CVT Calibration" must be performed using a professional diagnostic scanner (Nissan Consult-III, Chrysler wiTECH, or equivalent).
Cooler Flushing: The transmission cooler and lines must be flushed or replaced. Metal debris from a failed CVT will destroy the new valve body and pulleys immediately.
Transfer Case Mating: Ensure the PTO/transfer case section is properly filled and the rear driveshaft splines are lubricated with assembly grease during mating to prevent binding.

Common Issues & Maintenance:

Step Motor Failure: The JF011E relies on stepper motors to control pulley ratios. Wear or debris can cause the transmission to get stuck in a single ratio (limp mode). Regular fluid changes prevent this.
Overheating: 4WD systems generate extra heat. Ensure the radiator/CVT cooler is clean. Installing an auxiliary cooler is highly recommended for Jeep Compass/Patriot off-road use.
Bearing Noise: Whining or humming often indicates wear on the input shaft, secondary pulley, or differential bearings, a common wear item in high-mileage units.
Fluid Service Intervals: Strict adherence to fluid change intervals (every 40,000–60,000 km) is critical for the longevity of the JF011E push-belt and pulley surfaces.
