I have a chip to custom burn & plan on an exhaust/intake combo soon. Your tranny should be just fine if....
you install an add on transmission oil cooler. They're easy to install & you can pick one up at your local parts store, or order one on-line. I strongly recommend the high efficiency stacked coolers.
When you install it, you'll be flushing the old tranny fluid. BE SURE THAT YOU DO NOT USE MERCON V!!!!!!!! Use only Mercon fluid (up to Dexron III, if I recall corectly).
According to AAMCO the #1 killer of automatic trannys is HEAT. The #2 killer of automatic trannys is low fluid level. The lesson here: keep track of how much fluid you drain out of the transmission & replace that much PLUS extra for the volume of the new cooler.
Enjoy your ride!
