That’s why I stick to factory fluid when it comes time to change ATF in my cars.

My theory is that the formulas of different brand’s ATFs is slightly different, especially in terms of friction modifiers, which is critical in a traditional AT. Changing brands changes the shift feel of your AT from what you were used to...leading to complaints even if the AT is shifting fine, just differently.
which atf does your car asks for?


ano kaya mga sasakyan ang nag cocomplain? j have a feeling mali lng talaga nilalagay ng ibang shops when there was still no internet... walang reference to proper fluid for that car thats missing their owners manuals.
