Application: Designed for Hyundai Mistra (DU) 1.8L gasoline engines with Start/Stop functionality.

Key Features:

• Enhanced Belt Drive: High-strength push belt with widened pulley contact area for improved torque handling (up to 180Nm).

• Start/Stop Optimization: Reinforced auxiliary pump maintains hydraulic pressure during engine restarts.

• TCU Logic: Adaptive shift mapping for fuel economy and reduced belt slippage risk.

Failure Modes:

• Belt Wear: Contaminated fluid (non-SP-IV) causes pitting → shudder (P17F0).

• Auxiliary Pump Failure: Leads to delayed engagement after auto-stop.

• Pulley Sensor Faults: Causes erratic ratio changes (P0706).

Critical Notes:

• Fluid: Hyundai SP-IV CVTF only (every 60k km).

• Break-in: Avoid aggressive acceleration for first 500km to seat belt/pulleys.
