So I have to do around 3 drain and refills? Yeah the car is shifting fine, so should i just stick to this method and not do the flush? Also how much atf mercon V fluid do i need for the car to do the drain and refills? And do i do it all the draining and refilling at once or after certain intervals? Thanks javim for your time helping I really appreciate it!
First off make sure you use the right transmission fluid. Not sure which model you have 6i or 6s but they use different fluid depending on year and tranny.
Actually if you have a 03-05 6i Mazda calls to use Mazda M-V fluid. I've used Mercon V for several years now w/o issue. If anything it has lessened cold start shift shock. Just wanted to throw that out there FYI.
If the fluid is as bad as it is I would try to do it at once if you can. But to do that you'll need to drain, fill, drive around the block to mix new fluid and old. drain and fill again. I'd drain and fill at least 3 times.
Also I'd recommend draining and filling every year or so to keep the fluid fresh and clean.
No problemo for the help,Man, happy to help.
