How do you check the fluid level in a muncie 4 speed transmission?

To check the fluid level in a Muncie 4-speed transmission, start by locating the fill plug on the side of the transmission case. Remove the fill plug using a wrench; the fluid level should be just below the fill hole. If fluid drips out when the plug is removed, the level is adequate. If not, add the appropriate type of Transmission Fluid until it reaches the desired level.
