Since the transfer calls for 1.0L and the LF 75W is exactly 1.0L, did you find you had enough to fill it to the point it dripped from the Fill Plug? It woudl suck to have to get 2L of that stuff just for that little extra to get it to the right level....
When I did mine I had bought two cans of the 75w fluid. Of course since it comes in the old fashion metal oil cans you have to put it in something else first so you can pour it into the fill hole.
I used an empty plastic gear oil bottle with the narrow top, W/M Super Tech gear oil bottle to be specific that I have saved for just such a purpose.
Of course that is only a quart bottle so it has to be refilled with the 75w to get the entire liter in. When I had put the entire first liter of 75w in the case, it was still not dripping out the fill hole. So I opened the second can and poured it into the gear oil bottle and started putting it in the case, well it just took a little bit until it started pouring out the fill hole.
My suggestion would be to go ahead and order two cans, but when you get ready to put in the T/C, only open one can and put it all in, then take your finger and stick it in the fill hole and see if it is just about full. It may be that the second can would not be needed to be opened and could be saved until next time.
I may have lost some product in the process of pouring it from one container to another and pouring into the case, I have just about a quart left over from the second can that I opened (my gear oil quart bottle is full) so it did not take much out of the second can. And some of that just poured out the fill hole when the case got full.
Note that I did this transfer case fluid change at 60k mostly highway miles, the fluid that drained out was pretty clean, with very few metal shavings. I don't use the 4x4 all that much, someone that does a lot of heavy off road driving may need to change this fluid more often.
Also note that I changed my rear differential lube at 20k miles and again at 50k miles, it was fairly dark colored and had some shavings on the magnet at 20k. But at the 50k change it was still pretty clean and almost no shavings. I used Amsoil Sever Gear 75w90 gear oil.
I changed my front differential at 60k, it was almost factory clean fluid with virtually no shavings.
