Another great video guys.
Here are my comments based on the dozen or so times I had to drop the pan when I was having tranny issues:
If you don't want to drop the sway bar, you do not have to. You will just have to work around it to get to the pan bolts in that area but the pan can come out with the sway bar in place. I used a rubber reusable gasket which hasn't leaked a drop in the numerous times I had the pan off and on. Nothing wrong with the FIPG, it's just a pain to remove it and you have to be careful when re-installing the pan so that you don't smear the sealer off.
If you are in a pinch and you cannot find a replacement filter, you can probably get away with reusing it. But, I would suggest replacing it if possible.
The other issue with using the old filter is the fact that the cork gaskets that are glued in place often come loose. The cork also becomes compressed over time and may not make a good seal if reused (again why you should probably just replace the filter).
I still have the old filter that was all plugged up with clutch material (way worse than what was on yours Tim). I used brake cleaner and sprayed in there the best I could, I also did shake the hell out of it until clean brake cleaner came out. I then used my inspection camera to look in the filter the best I could and from what I saw, it looked clean.
When I have time, I will cut open that old filter and post a picture of it on here. That will let us know how well cleaning the filter actually works or not.
Again, I would take Tim's advise and just replace the filter but in a pinch, you may be able to reuse it.
