You use Mercon V in the tranny...

Welcome to FTE and or neck of the internet. You will always get an answer here, we were all newbies at one point.

Don't feel bad about asking questions the only dumb question is the one that you don't ask.

I went throught this same experience recently. The problem is that when your truck was new, it used MERCON fluid which was produced under a Ford license. So your dip stick still says MERCON. Some years ago, however, Ford put out a technical bulletin upudate that now calls for MERCON V in your tranny. You can still use MERCON, however, it is not recommended because the quality control that the Ford license used to ensure is no longer in place.

Your owners manual also calls for MERCON and probably even has a warning about using anything else. That makes it hard to be sure that your auto parts store is giving you the correct information.
