ok so my truck has a 4l80e tranny in it, not sure what the t case is but it doesnt really matter, my transmission fluid is in my transfer case , as in the fluid i put into my trans dip stick is going into my tranfer case, i am thinking there is a rear seal on the tranny or front seal on transfer case? that is gone and the tranny fluid is leaking into the t case or do they just share fluid? i just replaced my rear t case seal and i figure that it was pushed out because the t case was over full help me out
