mercon/mercon V mixed ?
ruby2,
Good for you! Glad to hear you got it straightened out. You did the right thing following up.
Don't worry about the wrong stuff being in your tranny for such a short period. Once it's flushed out and the Mercon V is pumped in, you'll be all set.
And you could say there's a silver lining in that your tranny ends up being flushed twice, so it ought to be nice and clean.
