I own an 2004MY 3.7L Liberty with MTX 5-speed NV3550 transmission. I am trying to locate fill plug to replace gear lube with Amsoil and have hard time locating it. Can any one please help me with its location and the socket type and size (i.e. whether internal hex, torx, etc.).

I have read that it is on the driver side but can't seem to find it. I see that there is a boss on both the sides (opposite to each other in line with the drain plug which is 17 mm internal hex) but not sure what they are for. Any help would be greatly appreciated!

Thanks a bunch,

Jignesh

On this NV3550 transmission, both fill and drain plug require 17 mm hex bit.
