Our '06 Outback (106,000 miles) is exhibiting slight rough shifting up only, downshifts apper normal.Not bad, but up to now shifting as been 'invisible'. Doesn't make any difference if loafing along or mashing the throttle. When manually shifting with sport mode, shifts are smooth. Car has had regular SOA maintenance, including AT service on schedule, with OEM tranny fluids only. Just did the 105,000 front case work, and tranny service ... still the same.
