Hello everyone not sure if this is the right area but I just recently had problems with my 2005 lly transmission. My trucks been working fine no issues then suddenly I got in it to go home from a buddies house and when I put it in gear it was loud, clunk, jerked my truck I looked at the dash and the range selector didn't have a line under it like normal. I then looked at my edge cts2 and noticed my gear tcl wasn't showing. Glanced at the trans temps and they read 0 looked at the edge and it wasn't registering a trans temp. Then the abs/brake lights came on. And noticed when I put it in drive the doors didn't unlock. I tried to drive it home anyways since I wasn't too far but the truck stayed in one gear and never shifted. Went back to my buddies and with the research I've looked up it sounds to me like my nsbu switch is bad. Can anybody give me their inputs before I go spending money on parts I may not need.
