Defect
On the automatic transmission of route buses, the return spring of the shift valve in the valve body—which controls gear position—has insufficient strength. Continued use may cause the spring to fracture, impairing gear changes. In the worst case, the transmission may become fixed in neutral, preventing the vehicle from moving.
Corrective action
On all vehicles, replace the return spring with the corrected part.

状況
路線バスの自動変速機において、変速ギヤ位置を制御しているバルブボデーのシフトバルブのリターンスプリングの強度が不足しており、そのままの状態で使用を続けると、当該スプリングが折損するものがある。このため、ギヤ段の変更に支障を生じ、最悪の場合、ギヤ段がニュートラルに固定されて発進できなくなるおそれがある。
改善措置
全車両、当該リターンスプリングを対策品に交換する。
