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

I am about to flush my transmission fluid and I wasn't sure how much to put in there. The manual says over 3 qts, but other guides say 2.25 L (2.4 qts). It's a 2000 boxster s.

just buy 4 quarts and fill the gearbox till gear oil drips out the fill hole. If it takes less then return then return the unopened containers of gear oil, if any.

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.
