I have an Stock qc 06 3500 4x4. Tranny and t/c were replaced under warranty about 40K ago. Only ran smarty on catcher #1. No problems whatsoever I just want a 6 speed because I live in the mountains. I am also looking into buying a wrecked truck but figured I would make this offer as well. Tranny is stock except for a ats valvebody. I'm located in Angels Camp Ca let me know if you're interested. You can drive the truck before hand to verify. Thank you. -Mike
