Re: Transmission oil contamination
As long as Royal Purple is equivalent to ATF+4 and is compatible with other ATF+4 fluids (which I am pretty sure it is), you shouldn't have a problem. Driving it any significant distance when 2 quarts low could definitely cause serious problems in short order though. Hope they didn't ruin the transmission for you. I am sure you'll have a fight on your hands, even if they did. Good luck, and let us know what happens.
