My car has 97000 miles.
My car has an automatic transmission.

Your overdrive uses a lock up converter that is supposed to lock the transmission input shaft to the engine so there is not slippage. You are not supposed to tow or carry heavy loads with the transmission in overdrive. You may have overloaded the transmission to the point that the converter lock up clutch slipped and the transmission will downshift out of overdrive when this happens. You may need to have the system tested for slippage.
