2006 Toyota Tundra Q&A

2006 Toyota Tundra Question: What is low pitched vibrational sound when stopped in gear? It stops in N or P.

When I put it in neutral or park the sound quits. It appears to be from transmission since it stops making vibrating sound. Any advice or solutions. -

Thanks for reply. Found the problem. Bolt on skid plate missing. Enough to cause vibration. -
