Change Trans Fluid Message


DESCRIPTION
The PCM calculates a Transaxle Fluid Life Index using transaxle temperature and engine state, running or OFF. The Transaxle Fluid Life Index represents the remaining useful transaxle fluid life as a percentage of total life. When transaxle fluid life reaches 0%, the CHANGE TRANS FLUID message will appear. The Transaxle Fluid Life Index can be reset using the Reset button on the Instrument Panel Cluster (IPC).
