I recently bought a 2011 Mazda CX-9 and love it.
One of the first things i noticed after i got home, was that it did not have a dipstick on the transmission to check the color or level. Now I generally keep my vehicles for 8-10 years so this is sorta new for me.
I first looked in the owners manual but it doenst have any mention of the transmission or service schedule.
So i called Mazda USA, and two other dealers...and got 3 different answers. Please help...
Mazda replied in writing that this is the first year for the CX9 to have a "sealed" transmission...no dipstick. Mazda says this is a sealed transmission and does not need to be serviced.
Dealer #1 said to come in at 30k miles and they would flush it for $200.
Dealer #2 said to come in at 90k miles and they would flush it for $200.
So...what is the recommended service intervals on these newer "sealed" transmissions. From what i hear allot of different vehicles have been doing this for years...just new to me. I've had honda's in the past and im used to a drain/fill every 30k miles.
Which brings up my second question..drain/fill or flush? I've never had a transmission flushed...always drain and fill.
I've heard stories about the flush causing problems. And what about the magnet on the drain plug. When i do a drain and fill, i always clean the magnet of any debris and inspect for shavings. When i asked the dealers about this, they said that they do not remove the drain plug..the machine will "flush" all the bad stuff out. I guess im just old-school...any opinions on this. (drain fill vs flush)
