The car drives perfectly when on the freeway, I can drive hours and hours but as soon as I am driving in traffic or peak hour traffic for at least 30 minutes to 45 minutes then the car will not overheat but the gears will dissappear completely. I can be in motion or driving the gears will just dissappear, car will still idle as per normal (As if the gearbox goes into limp mode), no overheating at all. Then I must turn off the ignition and let the car stand still for approx. 5 - 8 minutes then restart and all will be normal again til the gears dissapears.
