Transmission oil change or a flush for 11 mazda 3?

[justmazduh]

bought the car used at 65km so I dont know if the previous owner took care of the transmission so at 89km I did my first transmission drain and fill, now Im at 108km having some problems shifting the gear so i checked the tranny fluid when the car was warm and engine running. Checked the fluid and the fluid is black. So its about time to replace the tranny fluid. Now I was wondering if should I do drain and fill or a flush? Please let me know, thanks.

I think what most people say here is a drain and fill is just fine. I went with a flush when it was due and it's been running great. You can't really go wrong with either one.
The only thing to consider is that not every shop can do a flush so it's better to call ahead if you opt for a flush.

If trans isn't in good shape and you want to be safe. Do drain and fill.

I would say check Mazda Manual/OEM specs for when or if a Auto Transmission flush should be done.
