Oil Reservoirs
For oil reservoirs with side filler plugs (transmissions, axles,
steering gear boxes, transfer cases, etc.), the oil must be
level with the filler opening.
NOTE: Use care when checking the oil level with a
finger. Just because you can reach the oil level with
a finger, does not mean the oil level is correct.
