you might want to look into getting a handheld tuner.....this only increases line pressure and does heat up the tranny quite a bit depending on the firmness that you have selected....u can adjust the WOT and partial throttle shift firmness as well as the shift points....the Diabo Predator woke my tranny up and shifted a lot firmer/faster, but the tranny does heat up some....i would also recommend a transmission cooler if you are modifying the tranny......a valve body is a more expensive route but i think ultimately there will be less wear and tear on your tranny....B&M, Transgo (sp?) and some other companies make shift kits as well.......the programmer also has a tune that adds more HP and TQ to your ride, so its like killing 2 birds with one stone......there are a lot of other paramteres that u can modify with a tuner as well, so it is a good investment.........good luck....
