Automatic Transmission Fluid
The torque converter and the transmission are
lubricated with Automatic Transmission Fluid

Do not tow the car or run the engine without ATF
in the transmission. The automatic transmission
may be damaged by even a tiny speck of dirt, only
a clean funnel or spout must be used when adding
ATF.

and changed at the intervals listed in your Mainte-
nance Schedule.
We recommend that you have the ATF and trans-

has the required lubricants and the necessary fil-
ling equipment.
If you suspect an oil leak in the transmission, have
your authorized Porsche dealer check it out imme-
diately.
