If I’’m being honest...the odds are extremely low that I’ll hang onto it long enough for that to be a concern. I don’t see it failing inside of 100,000 miles or so, so I should be fine. If it does fail...I would just sort a junkyard replacement instead of repairing the original transmission.
If you wait a year or two you will probably see subaru migrate away from the cvt transmission. The cvt design seems to cycle/rotate through the various auto manufacurers every handful of years.
In 2012 and 2013 one could hardly find a anything but a cvt in jeep's lineup but in 2014 chrysler seemed to drop that design like a hot potato....same as other manufacturers did before them.
