Filing in context
The Automatic Transmission (A/T) is the most frequently cited component category in this archive, appearing in 19 of its 4,890 filings. This filing is one of 25 Honda notifications from 2004 in this archive. For scale, 2,164 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 2 years and 3 months.
Defect
During automatic transmission lockup operation, lubrication to the 2nd gear is insufficient. On roads where sustained 5th-gear lockup driving is possible, the lack of lubrication causes abnormal heat buildup on the 2nd gear tooth surfaces, reducing gear hardness. Continued use may cause the gear to fail and, in the worst case, the broken gear may mesh into adjacent gears, rendering the vehicle inoperable.
Corrective action
On all vehicles, check the odometer reading. On vehicles that meet or exceed the mileage threshold, inspect the 2nd counter gear tooth surfaces for heat discoloration; if discoloration is present, replace the complete automatic transmission with a corrected unit. On vehicles below the mileage threshold, and on vehicles above the threshold where no tooth surface discoloration is found, install an additional oil feed line for 2nd gear lubrication.
Affected models & chassis ranges
This filing lists 1 type code(s). A vehicle is affected if its chassis number falls within one of the ranges below.

状況
自動変速機のロックアップ機構作動時に２速ギヤの潤滑が不足しているため、５速ロッ クアップ作動状態を持続して走行できる道路環境の場合、２速ギヤへの潤滑不足から当該 ギヤの歯面が異常発熱し、ギヤの硬度が低下するものがある。そのため、そのまま使用を 続けると、当該ギヤが破損し、最悪の場合、破損したギヤが他のギヤに噛みこみ走行不能 となるおそれがある。
改善措置
全車両、走行距離を確認し、判定基準以上の走行距離のものはカウンタ２速ギヤの歯面の 焼け状態を点検し、歯面が焼けているものは自動変速機一式を対策品と交換する。また、 判定基準未満の走行距離のもの、及び歯面が焼けていないものは、２速ギヤ潤滑用オイル 配管を追加で取り付ける。
