Automatic Transmission Fluid
The torque converter and the transmission are
lubricated with Automatic Transmission Fluid
(ATF). The final drive requires transmission oil.
See "Capacities".
Do not tow the car or run the engine without
ATF in the transmission. The automatic trans-
mission may be damaged by even a tiny speck
of dirt, only a clean funnel or spout must be
used when adding ATF.
The ATF and transmission oil has to be checked
and changed at the intervals listed in your Main-
tenance Schedule.
We recommend that you have the ATF and trans-
mission oil changed at your Porsche dealer, who
has the required lubricants and the necessary
filling equipment.
If you suspect an oil leak in the transmission,
have your authorized Porsche dealer check it
out immediately.
