So another thing I'd like to add since you're posting this for future reference for others, and while we're on the subject of RTV: (and I'm NOT pointing any fingers at anyone, I'm merely passing on good advice passed down to me by seasoned mechanics for those that MAY NOT know)
From time to time I see where someone has used enough RTV sealant to hold back the Nile River. Unfortunately I think they fail to realize that however much RTV squeezes out when parts are assembled can also squeeze INSIDE whatever you're assembling as well. This is bad for things that have oil pumps (like a t-case). Over time this excess RTV can and will come loose and begin to float in your oil, and thus get sucked into the oil pickup where it will clog the pickup screen and starve components of oil.
We must remember that if we are assembling two *machined surfaces* that only minimal amounts of sealant will be needed. A good way to do this is to squirt the sealant on a non-porous surface and use an "acid" brush to lightly spread a small amount on one of the machine surfaces. Make sure no bristles come off and get left behind! Let the RTV skim over for a few minutes then assemble. You'll experience much less excess RTV squeezing out, and no worries about it causing issues inside the case.
I've been using this method for years now, and my SYE hasn't leaked a drop since I installed it.
If you already knew this, don't mind me. I'll jump off of the soapbox now
