Is it complicated to change the transmission fluid like in the normal Mazda6? The other question I have is this, is there an optimal mileage you should change it out? Can I do it the week I get my speed6? Or should I wait?The fluid will make a difference when shifting in terms of smoothness. I just changed my tranny fluid to Redline MT-90. You'll notice the difference right of the bat. It's not a super huge difference, but much better especially during cold mornings or when the car has been sitting for a while when it's cold outside.
Just search for this in older posts. I have the same problem with mine. 14K and MT-90 in last week and it is better but not gone. Try shifting in low RPM's 1.5-2.5K before it gets worm. It helps with mine. I am still thinking about the dealer visit with this issue as they may pull a recall on me.Yeah i just got home from driving a bit and sometimes the car shifts very smoothly into gear (1st, 2nd and 3rd) and other times, it feels rough. I keep the RPMs always around the same level and if I only shift between the first 3 gears for a bit, like in traffic, it becomes smoother. But once I bounce up to 4th and 5th, the low gears feel rough again.
While the temperature has something to do with it, the tranny does feels as if some thing's off.
it sucks because I don't know what to tell the dealer...the transmission feels off half the time???
