transmission fluid replacement - 986 Forum - The Community for Porsche Boxster & Cayman Owners

For the 5 speed, 2.25 liters at 11 mm below the bottom of the filler hole.

Thats odd. I thought I deleted this post because I found out it's 3 qts shortly after posting. But I do have another question about this. I have two ramps (one for each tire in the back) and wanted to know if it would be ok to drain it out that way. I don't want the fluid leaning on one side and not coming out. Would it be recommended to use two standard jacks like the one that come with cars to get the front sides so it levels out or is this not a good idea since they are not the best ones?

if you're taking the plate off of the bottom. I do not recommend using ramps. I did this and screwed up my alignment and almost couldn't get the plate back on. In my case, I was doing tires and aligment the next week anyway, but would have been really upset if I had to get an alignment just because I changed my tranny oil early (did mine at 20k miles, just to get out any crud that fell in while they were manufacuring it.)

The six speed uses 3 qts.

The car should be level when draining and filling the tranny.

What do you mean by the plate? I'm just going to be using the guide specified here: http://www.renntech.org/forums/index.php?showtopic=7060

If you don't put it on a ramp, how are you supposed to get to everything? And I don't understand what you mean when you said you messed up your alignment.

Don't use ramps, use 4 jack stands and keep the car level.

There's a large metal plate underneath the tranny that has to be removed to access the oil drain plug. The rennlist post has 5 pictures of it.

Some of us have drilled a hole in it so that we never have to take it off again.

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.
Happy Boxstering,
