Why does your auto transmission make a loud whiringbussing noise upon decelleration?

A loud whirring or buzzing noise from your auto transmission during deceleration can indicate several issues, such as low Transmission Fluid levels, worn bearings, or problems with the torque converter. These sounds often arise when components are under stress or not functioning properly. It's essential to have a professional inspect the vehicle to diagnose the exact cause and prevent further damage. Regular maintenance can help avoid such issues.
