I will be changing the ATF in the SS very soon (100k). This is my first ever pan drop (with any car) so I am a little nervous. I bought the SS with 79k, so I am unsure what fluid is in there. But it looks/smells perfect, so I don't think it's the FF. I have spent stupid amounts of time researching this trans (4T65E-HD) and I still can't decide what to do. The trans actually performs perfectly (both before and after tune), which should come as a shock to those that know about them. I know I will be doing a pan drop and filter change. Here are my questions:
1. What filter should I use? I am debating between the Delco TF304 and the Wix 58837. I'm leaning toward the Delco just to avoid any headache.
2. Use a new gasket or re-use the old one? I am under the impression the old one is superior (material).
3. I am absolutely NOT a fan of additives (in motor oil) but I am kinda considering it for ATF. The only one I think I am considering is Lubegard. Is there a real benefit if I am using a good ATF to start with? I think I am going to use Valvoline's Full Syn Dex VI. I am a fan of synthetics. Thoughts on the fluid (s)?
4. OCI. What should my interval be? I am thinking either every 25k or every ~33k. I just don't have a lot of faith in this trans (again, based on LOTS of research). I definitely don't trust GM's 100k interval
.
I am being overly cautious because this trans is a well known problem child. I plan on seeing 300k+ on this car, so I'm looking for the best of the best, within reason.
Many thanks in advance!
