The following situations can cause the transmission to operate at higher temperatures: D Towing a trailer D Hot outside air temperatures D Hauling a heavy load D Low transmission fluid level D High transmission fluid level D Restricted air flow to the radiator and the auxiliary transmission oil cooler (if equipped). 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" in the Index for the proper transmission maintenance intervals. Check Coolant Temp This message is displayed when the cooling system temperature gets hot. Check the coolant temperature gage and the coolant level. See "Engine Coolant" and "Engine Coolant Temperature Gage" in the Index. See "Engine Overheating" in the Index for further information.

See "Engine Coolant" in the Index and have your vehicle serviced as soon as you can.
