What upgrades would be considered on a 10K tranny that would help longevity. I occasionally punch it in low gears but slack off 4-5 shift. Thanks!

There are plenty of kits to choose from, so it all depends on how much you want to spend and if your going to do it yourself or not. You can find our upgrades at http://www.ttspowersystems.com/GM_tranny_kits.html
