Note that Ford has revised the fill level from 1.0-1.125" below the hole to even with the hole.


Also if you are changing the fluid you will need Motorcraft XL-3 Friction Modifier Additive to keep the clutches from chattering.
Dont use anymore than absolutely required unless you like rebuilding your Traction-Loc.
