Filing in context
The Automatic Transmission is the most frequently cited component category in this archive, appearing in 8 of its 4,890 filings. This filing is one of 4 Mitsubishi notifications from 1994 in this archive. For scale, 2,884 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 1 month.
Issue
The retainer—the component inside the automatic transmission that maintains hydraulic pressure for the 1st, 2nd, and 3rd gear clutches—was manufactured with a machining defect. Continued use causes slight wear at the contact surface between the retainer and the oil seal, which may temporarily reduce hydraulic pressure. When this occurs, gear shifts produce excessive shock or acceleration performance decreases.
Corrective action
On all vehicles, replace the automatic transmission with a non-defective unit.
