Here`s the problem. When the car starts in the morning after leaving it overnight, I usually let it warm up for 2-3 mins before driving. The car feels like there`s no oil in the tranmission and you can feel a shift lag on Sport Mode. Even my foot stayed at the same angle, the speedo jumps within 200rpm. Usually after driving it for 5-10 mins, the problems goes away. I am worried since the weather is like 0 degrees here and it does that. However when I plugged in during -15 degrees, this doesn`t happened. This happened after changing the ATF 2-3 months ago. Has anyone encountered the same problem and what are the ways to solve? Thanks in advance!
