transmission fluid replacement

[Viper5]

I will go out and get some jack stands. Is there another place to put the transmission fluid other than the oil fill plug because I don't see how to replace the fluid in the hole from underneath. Usually you put stuff on the top.

I use a small manual pump to fill the tranny.
To get the exact amount I made a mark with a hacksaw on an allen wrench 11mm below the bend. This way I insert the small end and rotate it inside he tranny and like a dipstick it will show you the fluid level.
As it's been said, don't use ramps for this procedure, use 4 jackstands instead.
The reason is that if you remove the diagonal braces and the aluminum skidplate fro the car while it sits on the suspension (loading the suspension) the alignment will be out of speck and you may not even be able to re-install the parts.

I just picked up two sets of two jack stands. Where is the optimum place to put them so that they aren't loading the suspension?
Update:
I have the car on the 4 jack stands but now I've come into another problem. I've been trying to unscrew the **************** out of those nuts, but they won't budge. Am I supposed to use an electric gun for this?

Viper,

The fill plug is near the rear end of the tranny on the driver's side. And if memory serves, an S tranny is supposed to take 3L of fluid (so 3 quarts will be a bit low).

As far as getting the plugs out goes, they shouldn't be so tight that you need to use an impact wrench. Just use your longest ratchet and make sure you are turning the correct direction!

The manual says 2.8L for the S model which is approx 3 qts. I also have the service manual and it says just to fill it up as much as it goes and the 11mm guide is only for the 5 speed. I'm definitely turning them the right way but they still won't budge. It's got a lot of miles and maybe they've never been released before.

I'll offer my $0.02 here. Use only the Porsche lubricant, which is a shell product, or this Mobil 1 product

Anything else, and you will have issues with synchros. This is especially noticeable with the 6 speed. As stated above, these are transaxles, not transmissions, and the inclusion of the trans + the dif in the same housing requires some unique properties for the lubricant. Swepco was great for the old air cooled boxes, but I don't think it works well with the newer cone type synchros in the latest cars. I may be wrong, but I've had great results with either of the above two lubricants.

I sorta already bought the 75w90ns so I will stick with that. Many people said it fixed their grinding problem, but like I mentioned before it's probably the synchros anyway. Just seeing if this will work.

I unscrewed the cover and have acess to everything now. There seems to be a discrepancy, however. I have attached some pictures for reference.

In the service manual, it shows a picture of the fill hole. In the tutorial, it shows a different hole for this. Which one do I use?







The service manual matches with the second one.
The tutorial matches with the first one.

I don't want to use the wrong one. Although it said that they mix (differential and transmission) but I need to use the right one so I know how high it needs to be.

I also am still unclear as to how I'm expected to get the fluid into one of those tiny holes. I went out and bought a pump, but I don't think I can get the fluid in the hole still. This is what I bought.
