Like was stated above, it can overfill easy if you pour it in too fast. Get the Flat Rater out of your system when filling the transfer case. You really have to pump it in nice and slow. When you have about .68 quarts in you should start seeing it over flow, You should be fine by then. If you are certain you have poured in over 1/2 quart then you should be ok to know that you have filled it to an ok level.

 

i ran a hose up through the engine bay, then up to a funnel hanging from my hood latch ring, filled the funnel with the proper amount, took all night to drain into the case 100%, but it worked, it was cold out tho, so it might go easier if the fluid is warmer

 

Yea definitely make sure the fluid in the tcase and the fresh fluid you'll be pouring in are both warmed up a bit if you're doing this during the winter.

 

I used the evomoto method until I got a fluid evacuator...now I pump it out and pump back in. No mess.

 

How would you get under the car to do any of this?

Edit: I see the funnel idea now, still seems like a pain. Lift please haha

 

It's not too bad just time consuming to lift then drop then lift again

 

If you set the car on 4 jack stands in a garage or level ground you should be fine. Atleast that's how I plan on changing out my fluids so I don't have to raise and lower the car over and over.

 

Yea. I just put the car up on 4 jackstands and do the rear diff at the same time. For the transfer case, last time, I poured it in until it overflowed then let it sit overnight and poured some more in. I drove it around for a week then put the car back up on 4 jackstands and tried to pour more into the Transfer case.

I will probably be doing it that way from now on.

 

is there a certain angle that "helps" you overfill the t-case? i.e., if put the car up on ramps as opposed to level, will it overfill better, or will it just spill out earlier?

 

ie, what if I only jack up the drivers side and fill like that?

 

You would want to jack up the passenger side only as the fill bolt is on that side

 

perfect I can do that- but is it a good idea or would it get too overfilled

 

It wont get too overfilled. Its perfectly fine to jack up on one side to be able to get under the car. Just be aware of the total fluid going in this way you know it wont be overfilled. I think it may be hard to overfill it to the point you will damage something. You would seriously have to want to try to overfill it I think.

 

I think a slight overfill is fine, but there's certainly a point where too much is just as bad as too little.
