How to Check Lubricant
To get an accurate reading, the vehicle should be on a
level surface.
If you have the 1500 Series, the proper level is from
5/8 inch (15 mm) to 1 5/8 inch (40 mm) below the bottom
of the filler plug hole. The proper level for the 2500 and
3500 Series is from 0 to 1/4 (6 mm) below the bottom of
the filler plug hole. Add only enough fluid to reach the
proper level.
