I have a 6.6 duramax with an auto transmission. The steel v sits right on the rubber. I saw a little separation so I used a prybar and it was separated the metal and rubber so it seems to have full movement up down and side to side but it only moved a little when I tested it. I don't suspect I need to worry about it because of the width of the mount but I thought Id put feelers out to see if anyone has seen trouble with the mount or has seen a similar issue? thanks.
