Hello! I drive a Toyota Yaris 1.3 sol with automatic transmission. I am a professional commuter and so my Yaris acquired at the end of 2004 has already run 50,000km. With all the nörglers who have been in the Toyota forum lately, I first have to tell my pronounced satisfaction with the car. My Yaris had so far no breakdown, always starts immediately and the oil consumption is at 0.0. Not even a light bulb I had to change so far. Almera (with Renull technology) used other things. Nevertheless, I have a few questions.: 1.) The automatic transmission also switches uphill up to the fourth level. Then, of course, it no longer pulls uphill and slows down. The overdrive (4th level) can be switched off for this reason. Question: Can you switch the overdrive on and off without hesitation at speeds of around 100km/h. Do you have to go off the gas before? the operating instructions do not give any information about this. 2. There Several times there was a slight lack of transmission oil, which is expressed in shiftbacks. But leaks are not to be found around the transmission. What can be lazy there? 3. The car “fits” regularly V-belts, because the wheels probably do not stand in an escape. Also caused by annoying noises. My dealer has so far no remedy besides silicone spray. Does anyone else have this problem? I thank you already in advance! Greeting Christian
