just went to silver and while driving in 2wd at higher rpm's i could hear/feel somthing like the trany kicking out of 1st gear for a split second. just put a used trany in last month and everything looked good then. it has a dana 20 t/c. maybe transfer case popping out? probly going to take the trans out and look for "pieces" this winter. just wondered if anyone else has had this. thanks
