Transfer case swap questions!

Okay, so hopefully I'll be getting my dad's coworker to loan me his garage with a lift soon to swap out my transfer case that I finally got from Clinton. I have a couple of questions though before I jump into it. I want to change the fluids out and put in some fresh juice with it for when I put it in. But I don't see a drain plug or anything that seems to be one on there, or a place to add... Where would they be? And about how much can it hold? Next, is there a gasket of some sort that goes between the trans and transfer case? Metal on metal usually has some kind of a gasket I always thought. Any help at all would be much appreciated. And, if anyone feels like taking a trip to Pittston PA, let me know. I know I'll get bored halfway through it. :thumbup:
 
oil whats that? lol i havent ever checked it or changed it so im not sure... there is a gasket fastory on it there hard to find most people just use black rtv to seal it up works fine
 
Would I be able to make my own? I haven't checked with my supplier yet, so I'll do that too. If not, I'll find some kind of sealer. Would Indianhead work too?

Ummmmm...LOLWUT? You aren't looking hard enough.


Remove the 4 bolts the mount the Tcase dampner to the trans(takes a 13mm). BAM!! Magically the drain plug appears. To the top right of this plug, near the output housing of the Tcase, is the fill plug. They both take a 3/8" square.....perfect for a ratchet and a short extension.

I like to lather on RTV silicone on the plugs before re-installation. Don't over-torque them... case cracking is far too easy to do by over tightening.


And about how much can it hold?

Pick up 3 quarts. Pretty sure she takes 2.5 qts of ATF.

There is a paper gasket between the two from the factory. Usually it survives Tcase removal. Sometimes it doesn't. I don't run one.

Metal to metal requires a gasket? Never done an engine swap have you? I've never mated an engine to a trans with a gasket before....

Umm no. Built into the trans tailhousing is a drain "squiggle". If you block with drain "squiggle" with RTV/silicone, you have no early warning of a trans mainshaft seal failure or a Tcase input shaft seal failure. Some totally seal the joint with silicone and allow the tailhousing to fill with ATF from the trans or Tcase and keep topping off the trans/tcase. I'd rather know I've got a problem and fix it, rather than to band-aid it with more fluid.

I suggest no gasket or a factory gasket. NO RTV.
 
FX4 is correct on the fill and drain plugs. I used regular ATF to fill my t-case when I swapped it in. And I used red RTV on the tail housing when I mated the two together. Hope you have a helper or a transaxle jack to help hold the t-case up.

dude i aint even gunna lie its easer to lift it up then it is to mess with a trans jack,
 
Could be if you have the option of a lift like he has, but when you're laying on your back in the driveway its a PITA lol. I worked in a garage so I'm use to using a jack when a vehicle is up on a lift :)
 
Yeah, I'm gonna have a lift for the truck and a lift for the tcase. Makes it a lot easier. I'll probably reuse the factory gasket if it's in good shape, if not RTV it all up.

if you dont have anything on it what would stop water from geting in? lol

If the factory designed it as a drain, does that mean the factory is wrong?

IDK how water is gonna get in...tiny little hole it is. You dunk your rig into water higher than your rockers?
