Latio CVT Gear don't change at 80km/hr

[wkyap85]

Hi kelvin,

Recently my car seems forget to change to upper gear when i hit 80km/hr. The rpm will shoot up to 4000-5000. But it only happens twice so far. I found that this incident occur when i trapped in the traffic jam for long time. However, after i restart the car, it seems going back to normal.

Could this be due to gearbox problem? pls advice

thanks
