Here’s a detailed breakdown of the CVT (''ProTronic'') gearboxes in the Proton Prevé and Exora Turbo:

🔧 Proton Prevé Turbo – CVT (Punch Powertrain VT3 / ''ProTronic'')

Transmission & Performance

• Uses Punch Powertrain VT3 CVT, branded by Proton as ''ProTronic.''
• Paired exclusively with the turbocharged 1.6L CamPro CFE engine (138 hp/205 Nm).  
• Includes steering-mounted paddle shifters for manual-gear simulation.

Driving Characteristics

• Common complaints: noise (''whine''), sluggish response at low speeds, jerkiness when accelerating from standing starts  .
• Owners often describe pickup as awkward or inconsistent—''jerky in slow speed'' or ''like half‑bitting a clutch''  .
• Turbo Prevé’s body weight exacerbates the CVT’s low-speed lag; mid‑range cruising is smoother.  

Reliability & Maintenance

• Reports of noisy/transmission whining, though some CVTs last well if well maintained  .
• Turbo models have occasional oil cooler hose leaks—a known issue addressed via recall  .
• Regular CVT fluid and filter changes (approx. every 40,000 km) are critical for longevity  .
• Replacement gearbox costs are not insignificant, but manuals may incur costly clutch pump repairs  .

🚗 Proton Exora Turbo – CVT (Older Punch CVT variant)

Transmission & Performance

• Also uses a Punch CVT, paired with the turbocharged 1.6L CamPro CFE engine delivering ~140 PS / 205 Nm  .
• Transmission is an older-gen unit—still CVT, but less refined compared to newer Proton models  .

Driving Feel

• CVT is noticeably noisy (''loud gearbox''), awkward during acceleration and initial take-offs  .
• At cruising speeds it smooths out, especially when loaded with passengers—it can handle steep roads well  .

Reliability & Maintenance

• Similar maintenance needs: frequent fluid/filter change every ~40,000 km recommended  .
• Long-term durability often depends on driver habits—proper usage can yield gearbox longevity  .
