Does anyone have a procedure/or has replaced the transfer case O-ring between the transmission and transfer case? Mine is leaking at that location, and I think it's the only seal that's there unless there is something i'm missing.
Nothing looks damaged from outside so i figured it's an O ring problem.
I have a 2008 RL.

Thank you!

 

I think I need part 28 and maybe oil seal part 25? If anyone can confirm I'd highly appreciate it.
