Welcome to CEG
You might want to change the trans fluid, unless it has been done recently. I put Mobil 1 trans fluid in my 1998 Mystique, 80,000 miles. If it drives well and no Check Engine lights or overheating, it's fine. The waterpump often fails, causing overheating (mine did) at your car's mileage. It might be a good idea to change it to a metal impeller pump, although it is likely to have been done. If the coolant temp stays near the center of the scale, the pump is OK.
