I was wondering when you guys change the trans fluid. The car currently has 37,000 miles. Haven't changed it yet. Also should I go with synthetic fluid?

Thanks.

 

In my market, Mazda says it filled for life. & it doesn't have a fill bung or dipstick. I know in the real world this is totally unacceptable. I haven't gone out of my way to find a way to drain & refill it.

If you plan to keep it, I suggest changing the oil.

 

Oh OK thank you I will plan on changing it then.
