Question I have is. I own a 2006  mitsubishi outlander with 75,000 miles.  Has no  mechanical issues and the car is as pristine as it came out in 2006.

Question I have is when should I change it or should I not change the transmission fluid bi have checked it and its still red, no smell to it.

I've taken it to 2 mitsubishi dealerships and 2 mechanics as the manual says change it at 100,000.  Yet all I hear is that since I barely drive it to not change it. ??

The only thing one dealership said was to do a drain and fill, without changing the filter which is inside the transmission.

Could you provide some guidance on what to do?

Thank you
