I'm not sure if they are flat or not I am gona take it off tomarrowWhat should I tighten the new aluminum pans bolts to,,,,about 14 lbs.???Also,, whats the deal with the filter extension that lowers the filter about an inch,,is that just to keep it submerged,seems like that is a heck of an idea,they should all be that way..

I assume you are NOT talking about the solid aluminum pans, right? More like the shinny tin pans. First, do NOT use sealant. Second, make sure that it is flat. Third, don't overtighten the pan, use a torque wrench and tighten a cork gasket to 12 ft/lbs or the fiber gasket to 16. Lastly, look ABOVE to see that may actually be the real leak. Remember that gravity and airflow will tend to move the oil from the source to a lower spot and can fool you.

Leo is right, you need to be careful how tight you get those bolts when you use the Cork Gaskets. Most people wrench down untill the cork is pushing out over the edge, and that usually means it has split and will leak.

You never want to use sealant on the trans pan either.

As for the extension, its only needed w/ deeper pans. Even with the shallow pans, the filter is always submerged, you can usually see where the filter sometimes contacts the pan, thats how well its submerged.

Do not use the cork gaskets, they are junk. Napa carries a nice filter kit with a rubber gasket, this is made in USA. I will not use any other brand.

Quality (the key) cork gaskets are in some cases the best choices. I have never really liked the rubber gaskets that I see and often, when you buy one of the filter and gasket packages the gasket is too thin. Go to a tranny shop and buy a good one.

As to no sealant, first off, it is NOT needed and second it makes a big headache for the next guy who STILL has to fix the leak.

I worked with a guy at the dealer who must have had no luck with pan gaskets and he would put the yellow weather stripping cement on the gaskets. You were better off buying a new pan than spend a 1/2 hour trying to get this stuff off.
