Let's see. Either a chip or a shift improver kit is almost a must-have item. Both would be great. Improver kit will cure the overlap during shifts. Chip can reset the shift points in the AODE. A cooler is also a good idea. They are inexpensive and easy to plumb in. Check with Performance Automatic, Level 10, Trans-Go, etc, for the kit. I personally like AutoLogic chips. If you are on a budget then get the shift kit first. Then the cooler, then the chip.
Good Luck.
