You solved the problem yourself. DO NOT USE overdrive unless you are on an open road and driving over 55 miles an hour. If you do you could cause the transmission to start slipping and pay thousands to repair expectially if you are hualing a load.

Do you drive with overdrive on or off in your 1999 mercury cougar?
On a 1999 Mercury Cougar : Overdrive is the normally allowed position ( it won't shift into overdrive until the speed is faster anyway ) If you find that the transmission is frequently shifting between overdrive and drive ( such as hilly roads ) then it is best to use the transaxle ( transmission ) control switch on the side of your gear shifter to shut off the overdrive ( O/D OFF will appear in your gauge cluster )
