Hi Scotty! I've got a 2013 Mitsubishi Lancer ES with a whole lot of miles. To get to the CVT filter, would it help to pull off the drivers side tire to get to it? Also they didn't get me an O-ring. Shouldn't I replace that also?
Do you have a video of you changing the transmission fluid and filters on a Mitsubishi?

@chucktobias Thanks Chuck!
Old o-rings should not be reused. Scotty to my knowledge has not made a video about changing transmission fluid and filter on a Mitsubishi, but others may have. Try searching youtube. You may also find some useful information in the service manual for your car at charm.li.
@chucktobias Thank you very much.
