I purchased a '99 F150 with the 5 speed manual overdrive transmission. I'm wondering what transmission fluid to use. The owner's manual says to use Motorcraft Mercon ATF, but doesn't seem that Motorcraft makes that specific fluid any longer. At least it isn't listed on their website. So what would be best, Mercon V? Or would something else be preferable? Also, what brands do you guys like? Thanks for your help.

 

Any ATF will be fine, with Mercon V preferred, this has completely replaced Mercon. I use full synthetic multi-vehicle in mine.

 

Thanks GLC. I just picked up some Mobile 1. Should be good to go.
