2018 Compass Trailhawk, last year had the dealer swap the coolant and ATF. Now that my hoist is up, I want to get in there and service the diff and transfer case oils. Is there a transfer or is it in the transaxle? How well do the skidplates cooperate with cut-outs or not all. Am I gonna be pulling them down to get at the drain/fill plugs? Thanks in advance.
