Meritor Transmission
- Remove the fill plug from the transmission.
- Insert a finger or pipe cleaner into the transmission.
- Check that the fluid level is even with the base of the fill plug. The correct fluid capacity is established by the fill opening. If the transmission has two fill plugs, check that the fluid level is consistent at both fill plugs.
- If the transmission fluid level is low, check the transmission for leaks, and correct as needed.
- If needed, add the recommended fluid, until it is level
with the lower edge of the fill opening. See Table. for approved transmission lubricants. For more information

Do not mix types and brands of fluid, because of possible incompatibility. Do not use fluid additives, friction modifiers, extreme-pressure gear fluids, or multiviscosity lubricants.
