CONDITION SUMMARY:
TRANSMISSION DOWNSHIFT FROM 2ND TO 1ST GEAR IS HARSH

can vary depending upon the amount of throttle that is applied.
Action:
Should a customer express this concern, verify the condition and refer to the Repair Procedure below to update the Transmission Control Module
(TCM). Check and, if necessary, update the Engine Control Module (ECM) software also.
TOOLS:
