Default Tranny fluid suck t case dry

Is there any easy way to get the transmission to put the fluid back in the t case with out pulling the t case off

HUH?
Doesn't work like that.
Just cause they are bolted together doesn't mean they share the same reservoir.
Transfer case has a fill and drain plug.
So how do you know that the transfer case is dry?

I added fluid till it was full as the fill hole on the t case yes it does leak it's not major yes the tranny leaks it's not major so how does my tranny go from 1 pint low to quart over and my t case empty only had it idle for 30 minuts

Well that explains your question.
Details are important.
My understanding is that there are seals between the 2.
But it is also my understanding that one doesn't leak into the other.
Just leaks out.
But apparently not the case.
Thinking you are separating the two once you determine for sure that's what it is.

I could be rong but the 2 holes on the back of tranny match the 2 on the tcase and allow the fluid to transfer between the 2

The one thing I have read about is that in older XJ Jeeps the slip yoked is lubed from the transfer case.
But the two hole thing is a new one for me.
First thing that comes to mind is how do you maintain proper levels?
Thinking going up or down hill fluid would be transferred to one or the other.
Be interested to find out if that is true.

It just occurred to me that maybe the holes you are talking about are the weep holes.
Gives the indication of a bad seal.

The transmission and transfer case fluids are seperate and don't mix. What vacuum in the transfer case are you talking about?
