Needing help..insight. Hello everyone. I have a 2004 z71 avalanche with a u0107 code. Happened on a bumpy road. Hit a few bumps..vehicle went into limp mode. Then died and pulled the code u0107. Checked all fuses and relays. Confirmed voltage on 3 month old battery. Reduced power reads Instrument cluster will NOT indicate current gear, no park, no neutral, fuel pump wont prime. Code reader will not work either.Now..if you shut the driver side door really hard or bang on upper portion of fuse box by driver side...the Instrument cluster now reads park and all other gears Intermediately. Codes can be ready and reset..byt immediately goes into limp mode. I could only get normal throttle for about 35 seconds. Is there a location under driver side dash related to the Tac module. Also..any ideas how to diagnose this or What to do and where?
TIA
