I have this strange little thing going on when changing gears on my 09 AC 4x4 6sp. When shifting between gears the RPM's hang, meaning when I lift my foot off the gas, the RPM's don't drop. It's like their waiting for me to complete the gear change and step back on the gas. I spoke with my dealer and test drove another 6sp and it did the same thing, so I'm guessing it's normal? By the way....I hate it! Anyone know what the deal is with this? Not sure why I didn't notice it before but I only have 640miles on the truck so I'm still getting to know her.
