Changing 986 manual transmission oil

[Richard Wyndham]

I'm just sorting out what I need to do for my annual service for my April 1999 65k miles 2.5 Boxster - owned by me from new.

Although low mileage, I have a major service every 4 years, and change brake fluid every 2 years, and fresh Mobil 1 oil every year.

I note that the transmission oil should be changed every 96k miles - which I am not yet near, however I see that the 987 series quote a change every 120k miles or 12 years. As mine is 13 years old, is a change advisable, or just leave well alone. (Gear changes are fine)

Thanks.

[8D]Hi Richard,
It is definitely worth changing,I bought
my car last Aug,it's an 02 S version.
When I changed the transmission it was
quite dirty and this was only after 39k.
It was not an easy job,because you have to
remove the torsion bars to drain it off.
I got a print off from rennlist and pelican parts forums.
The Porsche opc print off was useless.
I used the Mobil transmission oil,they do recommend
Swepco as the best but hard to find!
Your gear changes are a lot better and it does
Transform the car.
I change mine every year or about 3000-5000
miles.
Cheers
