Also do a coolant flush, Prestone sells a liquid that cleans out the entire system before you do the flush just run it for like 2 days in your car and presto, swap the coolant fluid.

Check the integrity of your bands.
Brakes, tires, suspension... Maybe the hosing should be considered too. Make sure the oil you use is like 1 level thicker than the recommended due the wear on the Pistons... That's all I can think of...
