What is involved changing the lines on a 2007? I am leaking going up into the transmission. Do the lines just fit snugly in the holes or are there any nuts or retainers that I can't see holding them in? I know they are quick connect but I have never messed with those. Since I have had surgery on my wrist I limited use of my left hand right now and if changing the lines is something that can't be done very easily I will need help.
