Did the transmission oil on Cultus myself through speedo meter cable hole. Did losen up the filler hole to avoid overfills it took about 2.5ltrs exact. But I was shocked as only one liter came out when I drained it. There was a leak around speed meter cable and previous owner probably didnt pay attention to it. I have driven it over 25000km without knowing what the level of fluid was in there it was running fine I hope it hasn't caused any damage to the transmission.
