Sorry to jump in, but I'm curious too. I have yet to put my truck on the road, but I want to know now. I've read about the plenum gaskets clogging the cat and cracking a head. I've also heard from just about everyone out there that these trucks have a lot of transmission problems. What exactly are these problems? Specifically? My truck hasn't even hit 134,000 miles yet.
Sorry to jump in...pretend this is a bump!
