Hello everyone I've been having an issue with a 2015 silverado 4x4 5.3 a couple of weeks ago coming home from work my truck went into limp mode, it wouldn't accelerate and wouldn't shift past 2nd gear i got it home checked tranny and engine fluids found no issues disconnected the batteryand got it going ,now it feels like its misfiring and struggles to accelerate I replaced throttle body, maf, map,sparkplugs, thinking it was an air fuel issue but it started making some rumbling noises at the wheels randomly (like rumble strips) when i scanned it the only code its giving is u0073 ebcm communication lost there is no abs light or check engine light I have checked visible connectors and wiring and the resistance on the can looks good from the obd port I'm trying to find schematics or any information ,assistance would be greatly appreciated thank you

Yes the bearings are in good shape pads and rotors have even wear as well everything feels solid
