Ano na ba Kondisyon ng ATF fluid baka marumi na at dark brown palitan mo na . Depende na rin kung paano nag maintain ng Transmission iyong dating mayari ang ikatatagal ng transmission . Palitan mo na lang muna ng ATF fluid.

no idea sa history ng auto, ipapachange ko na lang yong atf this weekend, any suggestions po, for this kind of model, parang gusto ko is royal purple fully synthetic, id like make this car's engine and transmission good as new but sana na lang i would not spend too much....
