Okay I will check there as well. Checked grounds and replaced one to no avail. I got codes 920, 921 & 999

I will check all grounds and for codes and get back to you guys. I appreciate the help

This is my first post on here guys, I’m in dire need of your help. 8 days ago I had a rebuilt transmission with a shift kit and triple disc converter put in the truck; a mile into the test drive all gauges were lost. Inline Performance figured out that it was a bad PCM and put a new one in it. Today I had to run home for something and left the truck running in the driveway for no more than 10 minutes. When I came back out, no gauges we’re working but the tach, the odometer is reading No Bus and the transmission won’t shift out of 3rd unless manually done. Please give me ideas, I feel my case is different than a lot of other no bus threads on here seeing as I just replaced my PCM less than 2 weeks ago
