Frequent ATF change lang talaga ang alaga... and of course, dont shift to R while your car is still moving... nor D while paatras.

Tama si Yebo. Actually the more often you change ATF the better. Why? Simply because you CAN NOT replace all the ATF in one go. For example. My car's AT has a capacity of 8.5L. During my atf change last december, 4 liters lang nakarga.
