The position of my ATF cooler |
Ever wonder why is the auto gear unwillingly to change gear even when you stomp on the pedal? Usually at night/ cold weather I do not seem to face this problem. My guess is because the auto transmission is being stressed too much plus the hot Malaysian weather especially during high loads. This eventually will increase the fuel consumption due to wrong gear selection by the gearbox. Installing an ATF cooler for the auto transmission will hugely help to overcome this issue.
Eventhough I am using fully synthetic gear oil form Redline ® for my beloved Perodua Viva I still find the lack of power and sometimes have to down shift manually to overtake or going out of junction. However with fully synthetic gear oils I never encounter gearbox overheating even during hard acceleration or downhill. :)
