SM465 noobie question

[monster man]

OK, i've never had to do this before, so where is the fill hole for the SM465? Mine is all covered in grease and I can't find anything that looks like the fill hole and my owner's manual doesn't mention it.
Thanks!

drivers side towards the rear. Or just remve the shifter and fill it through that hole.

fill it till it begins to pour out the fill hole, close her up and your good.

thanks, I have a pretty good idea it's empty- the truck has about 400,000 miles on it and the maintenance was only done when it was new. My uncle told me the brake reservoir cap had only been off once since he owned it, and the crap that came out when I bled it proved he wasn't lying!

We'll hope filling the trannie will prolong the life of my input bearing
seems to shift good, so hopefully it's not terminal.....
