Welcome to HF. I MOVED this for you to the H3 section, where all H3 questions go.

I read English, but cannot understand what you are saying???? Perhaps slow down and provide accurate information. Example, what does "now I'll push up from transfer case is leaking" mean? What does a torque converter have to do with the transfer case output seal?

Check the play of the transfer case shaft. If there is, then you need to open and eliminate

I appreciate any help I'm sure you understood the post even though I talk texted it and some came out wrong I had to drop the transfer case to get the transmission down to change the torque converter and ever since I put the drive shaft back in to the rear of the transfer case it's been leaking and it didn't leak before so I did a new seal and is still leaks and try two more from dealership and one from another auto parts store and it's still leaks i appreciate your time to help figure this out

The old seal may have chaffed the shaft enough to make it smaller in diameter where it now sits on the shaft. Hence the leakage.
Might have to replace the shaft or find a smaller diameter ID seal with the exact same OD as the OEM.
I have seen it on pinion yolk shafts, CV shafts, etc. Sand and dirt with dolomite, granite and other hard stone in the mud can be very abrasive.

thank you I appreciate the help I'll see if I could find one and try that and what's the drive shaft out there is a little play on the output shaft not a lot but when you put the drive shaft in there's very little play almost none
