Checking and Topping Up the ATF Fluid

370235 Checking and topping up the ATF fluid

Tool






Checking and topping up the ATF fluid
Top up only with ATF approved by Porsche.

Information
- The stipulated fluid level (3) is extremely important to perfect functioning of the automatic transmission. It is correct if there is still a slight amount of ATF escaping at the filler screw (2) hole at temperatures between 30 C and 40 C.





Testing conditions:
- The transmission must not be in the reduced driving program.
- The ATF temperature must be between 30 C and 45 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 be standing horizontally.

1. Attach the filled ATF container (special tool V.A.G 1924) as high up on the vehicle as possible.
2. Place oil collection pan under the transmission.
3. Connect the Porsche System Tester 2 and call up the ATF temperature.

Information
- The ATF temperature must not be higher than 40 C at the start of the test.

4. Move selector lever to position "P" and allow engine to idle.

5. Put on protective goggles and unscrew the ATF filler screw (2). If ATF escapes from the filler screw (2) hole and if the ATF temperature is 30 C...40 C, the ATF level is in order.





6. Screw in the ATF filler screw with a new sealing ring and tighten it with 80 Nm (59 ftlb.).

Information
- The filler screw must be closed no later than when an ATF temperature of 45 C is reached.

7. If no ATF escapes from the filler screw (2) even though approx. 40 C has been reached, the ATF must be topped up.
8. Top up with ATF with the special tool V.A.G 1924 until surplus ATF runs out at the hole (2).

Information
- The filler hook must be carefully inserted into one of the openings of the ATF guard cap (4) on the filler hole. When doing so, do not move the filler hook upwards, since the oil guard cap (4) can spring off upwards.
