025CHA Automatic Transmission CVT For Aria 5 Model

025CHA CVT Transmission (Chery Arrizo 5) – 30-Second Expert Analysis:

Design: Compact transverse CVT with electronic torque converter lockup for urban efficiency (optimized for 1.5L/1.6L engines).

Key Features:

• Torque Capacity: 160-180Nm (reinforced chain vs. belt for durability).

• Shift Logic: Simulated 8-step "stepped" ratios via TCU programming for driver familiarity.

• Cooling: Integrated thermal valve prioritizes cooler flow during stop-and-go.

Failure Modes:

• Low-Pressure Slippage: Clogged filter or weak pump (P0841 + shudder).

  TCU Calibration Bugs: Causes delayed engagement (requires firmware updates).

  • Chain Stretch: Improper fluid changes (every 60k km) leads to P17F2.

  Pro Tip: Use Chery CVT-J4 fluid only – generic CVT oils damage chain coatings.
