Getting lazy in my old age and let shop install CV axle in my daughter's Volvo. Some of the transmission fluid leaked out and they topped it off with Dexron V. It had mainly Maxlife ATF in it before. I understand that Dex V had been reformulated to be compatible in units spec'ed for Dex III/Mercon. Just getting opinions on whether I should do a drain and refill and try to get most of the Dex V out or let it ride? Not sure how much leaked out, but I was charged for one quart.
