I replace back the original P2 dexron III atf oil and 2.8L (originally drain out). But problem remain.
However, I reset the ecu, it work well after that for short period of time.
It if I continue drive to teach my learning into ecu, the problem come back. However, it's not bad as originally b4 reset the ecu.
Btw, anyone know the proper way to cofigure the ecu after reset.?
Could it be the symptom of bad ecu ?
The best way to fill in the correct amount of ATF is to measure how much ATF was drained, provided no leak and no overfill previously. Just for your information you could drain another 1 litre+ if you left the car sit idle for 2 days or more after the initial drain. This is what I do if I know I'm not going to use the car for the coming few days.
You could check the ATF level at cold range (20 - 30C) when you first started the car after filling the ATF. To check at hot the temperature is within 70-80C. I normally use Infrared temperature gun to check fluid temperature. To achieve that temperature it is about 10 mins drive of 80km/h.
Anyway, from the way you describe I hope it is just one of the transmission solenoid faulty. I suggest you to go back to perodua SC BRANCH and let them diagnose the fault code produce by AT. I think they charge around rm15 for inspection. At the same time pretend you never do the DIY oil change and hopefully your warranty still intact. Good luck.
