Need 2 Fill Transmission Fluid

[jimbenton]

there is a box/bottle in the engine compartment this is below the acceptable fill level.
it says to add transmission fluid , but there isnt any openings that I can see to add fluid.

directions on the ( box/bottle or monitor) say to remove top and the some type of plug if I remember correctly and the add fluid. could this be on my alpha one drives? I have twin 4.3 engines with alpha one's
