:screwy: This site is FABULOUS! I have a couple more question, concerning my 2000 Trooper (with TOD). When I have the truck in 4 Auto, while driving at speed over 5 MPH the first 2 bars are always on (even if it is not slippery out?). Is this normal? Also I have a vibration at speed over 40, however while in 4 AUTO the vibration is not as sever? Any ideas? Thanks again this site and your responses have helped me drastically!
