Just got this V70 with 125000 miles. Put around 100 miles on it and it started shifting kinda hard and hesitating at times, like it was winding up and should shift but didn't want to. Check Engine and Transmission Service Required lights came on. I drove it 25 mile on the highway to get it home and it drove ok, but transmission still felt off. Transmission shop says filters inside so id end up having to do a rebuild for $3200! Any ideas?
