Filing in context
The Drive force transmission is the most frequently cited component category in this archive, appearing in 5 of its 4,890 filings. This filing is one of 150 Mitsubishi notifications from 2004 in this archive. For scale, 2,386 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 7 months.
Defect
The oil seal and O-ring in the chain-driven transfer case have insufficient heat resistance. During sustained high-speed driving, transfer fluid temperature rises, causing the seal or O-ring to deteriorate and allow transmission oil to flow into the transfer case. The additional oil increases chain churning resistance, raising fluid temperature further until oil is expelled through the breather vent. In the worst case, this can result in a vehicle fire.
Corrective action
On all vehicles, replace the oil seal and O-ring with corrected parts. Also replace the output-side oil seal and O-ring with corrected parts.

状況
チェーン駆動式動力伝達装置（トランスファ）の、オイルシール及びオーリングの耐熱性 が不足しているため、連続高速走行によりトランスファ油温が上昇した場合に、当該オイ ルシールまたはオーリングが損傷して変速機（トランスミッション）のオイルがトランスフ ァ内に流入することがある。そのため、チェーンの攪拌抵抗増加によって油温が更に上昇 して、オイルがブリーザから噴出し、最悪の場合、火災に至るおそれがある。
改善措置
全車両、オイルシール、オ－リングを対策品と交換する。 あわせて、アウトプット側オイルシール、オーリングを対策品と交換する。
