Description of defect

Some bolts fastening the torque converter to the drive plate in the automatic transmission may loosen at high engine speeds due to an inappropriate tightening torque specification.
If use is continued, in the worst case, the bolt may fall out of the torque converter housing, resulting in abnormal noise while driving.
