About a week ago changed a tranny fluid at some garage.
The guy put Mobil D/M fluid instead of M-V as listed. Changed only a gallon of fluid.
How bad could it be for a transmission?
Should I immediately change the fluid again? If so, how to do it to make sure that all of the wrong fluid will come out?
Thanks

Take it back and ask for the right fluid ASAP. But if it brings you any piece if mind. I've used Castol Mercon V for frequent drain and fill intervals for years w/o issue.

yea, just have them change it. since they put the wrong fluid in the 1st time, they cant charge you to fix there mistake.
