yesterday in the mail i ran into a coupon for a tranny fluid service for 90$,includes gasket and filter. it's one of the local shops "good year" i think is called, i don't know if they are a nationwide chain.
is it safe to take it for tranny change to one of these mostly "domestic" oriented vehicles shops" or always to a certified BMW shop. what is your thought?
can they really screw it up
