Defect & Vehicle Involved; Owner, Dealer, & Parts Information

DEFECT INVOLVED

General Motors has determined that a defect which relates to motor vehicle safety exists in certain 1989 M-Vans. These vehicles may have a loose retainer securing the automatic transmission control rod linkage to the steering column lower shift lever. This looseness may allow the retainer to disengage, resulting in a separation of the control rod from the lower shift lever.
When this occurs, the shift indicator may not reflect the gear the transmission is in. In this situation, the driver could believe the transmission is in a forward gear when actually it is in reverse, or vise versa. Additionally, the engine could be started with the transmission in gear. Either of these conditions could lead to a vehicle crash without prior warning.

To prevent this condition from occurring, it will be necessary to install a new transmission linkage retainer on all involved vehicles.

VEHICLES INVOLVED

Involved are certain 1989 M-Vans with automatic transmission (MD8) built within the following VIN breakpoints:
