1999 Protege - No Shift From 2nd or 3rd, O/D Off Indicator Light Flashing - DTC P0732, P0733 or P0734

APPLICABLE MODELS

All 1999 Protege with A/T and VINs lower than JM1 BJ22 X0 191527.

DESCRIPTION

No shift condition from second or third gear with a flashing overdrive off (O/D OFF) indicator light. This condition can be caused by a failed shift solenoid (A, B, C, D, or E). Unfortunately due to incorrect failure detection logic in the Power Control Module (PCM), some vehicles will have improper Diagnostic Trouble Codes (DTCs) P0732, P0733 or P0734 (gear incorrect) stored in memory instead of the appropriate shift solenoid DTC(s) as listed below.

Customers having this concern should have their vehicle repaired using the following procedure.

REPAIR PROCEDURE

1. Verify customer concern.
2. Inspect PCM part number (i.e. ZM02-18-881C).
3. Erase DTC and perform the following drive mode to identify actual cause (i.e. shift solenoid, control valve, etc.).
4. Check for any DTCs and perform applicable Workshop Manual Diagnostics.

NOTE: If DTCs P0732, P0733, and/or P0734 re-appear, use the service diagnostics on pages 3-9 of this bulletin. A Workshop Manual update will be issued which will contain these diagnostics.

5. Verify repair.
