:)Good Morning Everybody, I read a couple articles about the tranny flush vs drain. My TB have 26,000K. I will like to do the flushing using the cooling line method. How effective will be if I start using synthethic oil in step of the regular ATF. I will like to know if is not too late to change the one at the engine for synthetic as well. All my others car I always used castrol (regular)
5w30 with no problem at all, but I heard that synthetic have more benefits than regular oil.

Welcome to the forum, have fun and be careful. Synthetics help things last longer. Start using them as soon as you wish.
