Well, my 1999 Grand Prix got zapped recently, so I grabbed a 2007 replacement for my daily drive. This edition is at 95k with little, if no, PM having been performed on it. As I have been working my way through fluid & filter changes, I've transitioned over to MaxLife ATF and a bottle of Lubegard Red in the 4T65E transmission. (The prior fluid looked horrid!) In a few weeks I will probably do an ATF flush (DIY or machine style hasn't been decided yet). My question however pertains to what else I could do in the trans while I have the pan off. It's my understanding that some of the vitals are difficult to access from just a pan drop so I just need to focus on those things that are readily accessible. Are there any upgrade "kits" that I could install while the pan is off? Some characteristics I think may need attention focus on 1st gear, with a 1-2 transition being rather noticeable and the release after slowing to a stop being on the shuddery side too. Dunno if those things will just go away with better fluid maintenance and LG Red working on things for awhile, or if there is a mechanical issue that needs attention.
