Thanks for the info on what not to use... Now, drawing from your experience over the years; care to share what the best/correct gear oil IS?

We get ours from Porsche..............

From the factory, there is often a sealant like material on the plug that really makes difficult to remove the first time. Once it is loose, you will be fine. We clean the factory sealant off the treads and put a drop of anti seize on it before re-torque......

Awesome. Thanks for the info. That plug is making me crazy, lol.

Just went through that this weekend. Best way to get the plug out is to pull off the diagonal body brace underneath, it's just a bolt and a couple of nuts. After that you can with the right combination of extensions and breaker bar get a nice 90 degree angle on your ratchet/breaker bar and get the plug out with NO PROBLEMS. I spent 20 minutes trying with the brace in place and couldn't do it. Pulling the brace took all of 2 minutes and after that it was as easy as a girl from Surrey...

There are also other ways to change the ATF. For example the Tom Eckard method: Englisch

How much differential fluid I should add back in? I was only able to get about .3 liter of fluid out of rear differential on my 2003 boxster. Any info would be appreciated.
