So after 6 months I finally got to run and drive my truck. Trans is in though I think the converter seal is leaking a little about a dime size drop after sitting for a few hours. Sounded great while it was sitting idling but once I put it in reverse and started to move got a horrible rattling like sound and vibration. Put it in drive and both went away. Drove it down the street everything sounded good until I stopped and both came back. Hit a bump, turn the corner, hit the brakes there again. It had a slight vibration before but I only really noticed it if there was somebody with me. I had just about everything, short of pulling the motor, out. I did notice last week that there was not much room between the cab floor and the transfer case, and yesterday it seemed as the turbo was against the firewall slightly. Couldn't fit my fat fingers between the TC and the cab floor so that's why I'm thinking body mounts, they look a little pancaked under there....... So looks like I'm pulling the interior to get to the bolts??? Never done these so it ought to be a adventure....
