Auto Trans Clunk (loud!)
 

Hi all, appreciate your help! My '08 Camry's automatic transmission clunks when I engage reverse, after a transmission drain and fill. The car shakes as if I was driving over a pothole at 50 mph (has 200K miles). Also won't shift into overdrive at high speed sometimes, unless I manually downshift and upshift. Can anyone tell me if this can be fixed, and where to find more information? Is this officially called a torque shudder? Please confirm.
