Note the following information:
• Regarding the repair information. Refer to => [ General Repair Information ] General Repair Information.
• Regarding the Automatic Transmission Fluid (ATF). Refer to => [ Automatic Transmission Fluid ] General Repair Information.
• Regarding the "filler tube". Refer to => [ Transmissions With and Without Filler Tube ] General Repair Information.
• The Adapter for Oil Filling (VAS 6262/6) must also be used on some fluid container.
• It may be necessary to shorten the pipe on the adapter for oil filling (VAS 6262 A).
Shorten the Pipe on the Adapter for Oil Filling (VAS 6262 A) as Follows
- Shorten the pipe to 210 mm - a -. This assures the pipe on the adapter for oil filling (VAS 6262 A) will not touch the bottom of some oil containers.
• Dimension - a - is measured starting from the green surface in the cap on the adapter for oil filling (VAS 6262 A).
- Make a mark on the pipe, at dimension - a -, and cut it with using the pipe cutter (VAS 6056/2).
Special tools, testers and auxiliary items required
• Torque Wrench (5-50 Nm) (V.A.G 1331)
• Use Oil Collecting and Extracting Device (V.A.G 1782)
• Vehicle Diagnostic Tester, for example Vehicle Diagnosis, Testing and Information System (VAS 5051)
• Drip Tray for VAS 6100 (VAS 6208)
• Adapter for Oil Filling (VAS 6262 A)
• Adapter for Filling ATF Oil (VAS 6262/2)
• Also on some fluid containers Adapter for Oil Filling (VAS 6262/6)
Use the ATF available as a replacement part.
- Always replace the seal - arrow - for the plug when checking the ATF level.
Checking
- Turn off the engine.
The Automatic Transmission Fluid (ATF) temperature must not be more than approximately 30 °C (86 °F) at start of the test.
• The transmission is not in the emergency running mode, and the ATF temperature is not higher than 30 °C (86 °F).
• The vehicle is horizontal
• The selector level is in the "P" position.
- Connect the vehicle diagnostic tester and move through the selections until it is ready for operation. Refer to => [ Tester, Connecting ] Testing and Inspection.
- Press the "right" Guided Functions.
- Select the vehicle, the transmission and check ATF level.
- Press the -> button.
- Start the engine.
- Lift the vehicle.
- Remove the noise insulation.
- Place the used oil collecting and extracting device or the drip tray for VAS 6100 (VAS 6208) under the transmission.
- Press the -> button.
If the test temperature: 35 to 45 °C (95 to 113 °F) is shown:
- Remove the ATF plug from the pan - arrow -.
ATF should drain out of the overflow tube.
If the ATF continues to drain out of hole:
The ATF does not need to be topped off.
- Reinstall the ATF plug with new seal and tighten it to 27 Nm. The ATF level test is now completed.
If no ATF drains out of the hole:
- Fill the ATF. Refer to => [ Filling ].
Filling
• The used oil collecting and extracting device or drip tray for VAS 6100 (VAS 6208) is still placed under the transmission.
- Install and tighten the adapter for filling ATF oil (VAS 6262/2) into the plug hole hand tight with the engine running.
- Shake the container before opening it.
- Install the adapter for oil filling (VAS 6262 A) to the fluid container. Be sure to read the instructions.
- Fill with 1 liter Automatic Transmission Fluid (ATF).
- Connect the adapter for oil filling (VAS 6262) to the quick release coupling and check the fluid:
If ATF drains out of the hole:
The ATF does not need to be topped off.
- Allow the ATF to drain until it drips.
- Reinstall and tighten the ATF plug with new seal to 27 Nm. The ATF level test is now completed.
If ATF does not drain out:
- Fill another liter of fluid. Refer to => [ Filling ].
Too little or too much ATF will impair the transmission. If 2 liters are missing, you should check the transmission more closely. There is probably a larger leak.
Draining and Filling
- Turn off the engine.
• The used oil collecting and extracting device or drip tray for VAS 6100 (VAS 6208) is still placed under the transmission.
- Remove the Automatic Transmission Fluid (ATF) plug from the pan - arrow -.
- Remove the overflow tube - 1 - from the hole.
- Drain the ATF.
- Reinstall the overflow tube.
- Install the adapter for oil filling (VAS 6262 A) to the fluid container. Be sure to read the instructions.
- Install and tighten the adapter for filling ATF oil (VAS 6262/2) into the plug hole hand tight.
- Fill with 3 liters of ATF.
• On some older transmissions with a filler tube - arrow -, the ATF can be filled using the filler tube.
- Remove the adapter for filling ATF oil (VAS 6262/2) from the pan and install the ATF plug with the current seal.
- Move the selector lever into the "P" position.
- Start the engine, shift through all selector lever positions, you must remain in each position approximately 10 seconds.
- Check the ATF level and add if necessary. Refer to => [ ATF Level, Checking and Filling ] Testing and Inspection.
