So your t-case took less than 2 quarts?? You didn't have the front up in the air and the rear on the ground did you?
Also, i did check my fluid yesterday and it was within 3/16" of the fill plug so im good there. For my wifes KK im just going to fill it up to the drain plug like the manual specifies and see what happens. I have a few years left on the warranty so if something happens, its on them... i followed the instructions.
