Filing in context
The A/T is the most frequently cited component category in this archive, appearing in 32 of its 4,890 filings. This filing is one of 45 Hino notifications from 2012 in this archive. For scale, 4,195 of the 4,890 filings in this archive report a larger number of affected vehicles; the vehicles involved here were manufactured over a span of about 5 years and 9 months.
Defect
On transit buses with an automatic transmission, the torque converter cover flatness is out of specification. This causes some lockup clutch backing plate mounting bolts to fracture. Continued operation allows a fractured bolt to become trapped between the torque converter cover and the turbine. In the worst case, the torque converter locks up, causing an engine stall and loss of mobility.
Corrective action
On all vehicles, verify the serial numbers of the automatic transmission and torque converter. On affected units, replace the torque converter with a conforming unit.

状況
路線バスの自動変速機において、トルクコンバータカバーの平面度が不適切なため、ロックアップクラッチのバッキングプレート取付けボルトが折損するものがある。そのため、そのままの状態で使用を続けると、折損したボルトがトルクコンバータカバーとタービンとの間に挟まり、最悪の場合、トルクコンバータがロックアップした状態となり、エンストして走行できなくなるおそれがある。
改善措置
全車両、自動変速機及びトルクコンバータの製造番号を確認し、対象となるものはトルクコンバータを良品に交換する。
