Transfer case oil change procedure

[HereinDaRockies]

Looking to change my transfer case gear oil after grinding it while shifting from L to H. Want to flush out any potential metal shavings

The fluid spec I found cites two volumes - 1.8L and 2.64L

I am just doing a drain & fill. I am not clear what the 2.64L indicates.

Is the fluid change procedure similar to other 4x4 transfer cases? Just fill until oil comes out of the fill hole?

There is a cooler in the front bumper, the higher quantity is if you have drained that as well as the transfer case.
You are probably best to drain the whole thing then add the specified quantity of oil.

Are there instructions on draining & filling the t case cooling system?
