all you do is unscrew the drain plug (bottom plug) till it runs almost out...then plug it back up and take the filler plug (top plug) and fill it up till the fluids come out or 2 pints

imagine this:

you take off the drain plug, drain fluid, all is going smoothly.


now youre ready to fill it up through the fill plug, but..
"OH ****. I can't get this plug off for the f***in life of me."

now youre stuck, with no way to fill it up or go get what you need to get the plug off.






just avoiding any possible nightmares.




for example, I had to use a breaker bar and a lot of force to get the fill plug off my tranny, but just used the socket wrench to get the drain plug off.

No....

It's so that if there is a problem with the fill cap.. you haven't drained the fluid out of the T-case without a way to fill it back up.
