Presently, I am using coastal multi vehicle Mercon V ATF for almost 2 months now, and the shift is not smooth especially in the morning. I could feel the shift slightly as it changes, Performance is sluggish compare to before now, It tends to jerk very slightly as the gear changes. Apart from the OEM mazda ATF M-V, what other best compatible ATF would you recommend for a 2007 mazda 6i 2.3L (4cylinder)?
Thanks!
