Transfer Case leak?

[ahdoman]

I'm trying to run down an ATF fluid leak on Pearl. I suspect it may be the switch in the pic is leaking. I believe that is the 4H4L switch? Can someone confirm that for me?
If so;
1) Can I remove it without loosing a bunch of ATF fluid? Or do I have to drain the case first?
2) How do I find a part number for this if I need to order a new one? I don't see any part number listed in the service manual.

I didn't find it in the attached parts list either but maybe you'll have better luck than I.

Ok, it looks like I may have found my leak and it appears to be the drive shaft seal on the front of the transfer case (front wheel drive shaft). But, "tom4bren" was kind enough to post the VX Parts List but the transfer case info isn't in that document! Is there a driveline supplement or something? I'm looking for that seal number. It shows it in the service manual but no part number there either.

think you might find your part on Rock Auto dot com. Transfer case is listed under drivetrain:yeso:
