Hi all, when I try to accelerate my passo-2005 from 50 to 60 km, first the car does respond according to my gas pedal...then suddenly it gives a annoying jerk and start accelerating...is it a gearbox problem? I am using Toyota grade IV transmission oil. passo-2005 supposes to have automatic gearbox. But one mechanic suggested that my car might have a CVT gearbox since it possesses 4 sensors. Should I use CVT gear oil. I would be obliged to your valuable suggestion. thanks
