ISSUE:
Some vehicles may exhibit a flashing Transmission Control Indicator Lamp (TCIL) and harsh shifts with a Diagnostic Trouble Code (DTC) 62 in
continuous memory. This condition may be caused by the Powertrain Control Module (PCM).
ACTION:
Verify proper transmission function by performing diagnostic procedures specified in the Powertrain Control/Emissions Diagnosis Service Manual for
DTC 62. If the concern is still present, install a service replacement PCM. Refer to the PCM Usage Chart for correct application.

NOTE:
MAKE SURE TO PERFORM A PROPER DIAGNOSIS FOR CODE 62 AS OUTLINED IN THE PCED AND SERVICE MANUALS BEFORE
CHANGING THE PCM. IF THE VEHICLE HAS THE UPDATED PCM AND EXHIBITS CODE 62 IN CONTINUOUS MEMORY, THERE IS
A VEHICLE OR TRANSMISSION PROBLEM AND CODE 62 IS VALID. THE PINPOINT TEST LISTED IN THE PCED MANUAL AND
SERVICE MANUAL MUST BE PERFORMED.
