H55 Trans/Twin stick servicing?!

[FloTaco]

So I'm a new owner trying to go through all of the fluids and have read different information on how to fill the H55 trans and twin stick case. ANY help would much appreciated!

1. Does the transmission oil feed into the transfer case or do I fill them separately.

2. Is the upper transmission port in the picture the only filling location or is there one on top near the shifter?

Filled and checked separately.

There should only be a single fill hole partway up the side of the transmission. You couldn't access one any higher on the transmission anyway, due to tunnel interference.

Remove the fill plugs FIRST, BEFORE removing the drain plugs, so that you can be sure of your ability to refill the cavities after you drain them.

SOR.com should have diagrams showing this, among many other resources.

Gotcha, thanks. Why does so much literature indicate they share fluid?
