But you will be fine. Just in the future stick to Dex VI fluid and don't listen to the guys trying to sell you parts behind the counter.

Some you can trust. I'm the one who sends people to the dealership for fluids if we don't have the exact one that is designed for that app. In otherwords, we carry the "regular" green coolant, dexcool, powersteering for GM's and fords. Ford type F tranny fluid, ATF +4, Dex III, Dex VI and one other standard for Allision transmissions and the rest I won't reccommend. Straight to the dealer for the rest.

Some could say, I'm don't really rep my store all that well, but my defense is, I don't like selling people sh*t or the wrong sh*t.

Do just take some random dude's opinion on it.

I can second that, a lot of the stuff I hear other employees saying tends to be complete BS.
