Fluid - A/T: Testing and Inspection
Checking And Topping Up The ATF
Tools
Checking ATF
NOTE:
-
Top up only with ATF approved by Porsche. See Parts Catalogue!
-
The stipulated fluid level is extremely important for perfect functioning of the automatic transmission. It is correct if there is a slight amount of
ATF escaping at the filler screw bore -2- at temperatures between 30 degrees C and 40 degrees C.
Testing conditions:
-
The transmission must not be in the reduced driving program.
-
The ATF temperature must be between 30 degrees C and 40 degrees C. An ATC inspection at an insufficient ATF temperature causes
over-filling and an inspection at an excessive ATF temperature causes insufficient filling.
-
Selector lever in position "P" and engine idling.
-
The air-conditioning system and the heater must be switched off.
-
The vehicle must stand horizontally.
1. Attach the filled ATF container (special tool filling system V.A.G 1924) as high up on the vehicle as possible.
