TRANSMISSION HOT If the transmission fluid temperature becomes high, the message center will display this message. When the transmission enters the protection mode, you may notice a change in the transmission shifting patterns. When the transmission fluid temperature returns to normal, the display will turn off and the transmission shifting patterns will return to normal. Notice: If you drive your vehicle while the transmission fluid is overheating and the transmission temperature warning is displayed on the instrument panel cluster and/or DIC, you can damage the transmission. This could lead to costly repairs that would not be covered by your warranty. Do not drive your vehicle with overheated transmission fluid or while transmission temperature warning is displayed. The following situations can cause the transmission to operate at higher temperatures: • Low transmission fluid level • High transmission fluid level • Restricted air flow to the radiator. A temporary solution to hotter transmission operating temperatures may be to let the transmission cool down. If the transmission is operated at higher temperatures on a frequent basis, see Scheduled Maintenance on page 6-4 for the proper transmission maintenance intervals. TRANS HOT IDLE ENGINE If the transmission fluid gets hot, this message will appear on the DIC along with a continuous chime. Driving with the transmission fluid temperature high can cause damage to the vehicle. Stop the vehicle and let it idle to allow the transmission to cool. This message will clear and the chime will stop when the fluid temperature reaches a safe level. • Towing a trailer • Hot outside air temperatures • Hauling a large or heavy load 3-64
