Fluid And Fluid Level Troubleshooting

WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2010 Volkswagen Jetta, 2009 Volkswagen Jetta, 2009 Volkswagen GLI, 2008 Volkswagen Jetta, and 2008 Volkswagen GLI. However, it is still accessible from the selected car via links, so may be relevant.

For more information regarding the fluid, refer to FLUID FUNCTION . The transmission fluid cannot disappear without a trace.

Transmission fluid can only be missing if it has leaked from the transmission.

Transmission Lubricated

-- Determine where the fluid has leaked out of the transmission. Repair this leak first. Fill with new transmission fluid and make sure the level is correct. Refer to TRANSMISSION FLUID LEVEL, CHECKING AND ADDING .

Filling the fluid just in case does not correct a malfunction. It does not help to find the malfunction and it gives you a false sense of security.

Transmission Fluid Drain and Check Plugs

Up to transmission production date "September 20, 2004", transmissions with two plugs were installed.

Then the second plug was eliminated so that oil draining and oil level adjusting is done using only plug -A-.

A plastic overflow tube is located behind this plug (with a 8 mm hex socket head, tightening specification: 3 Nm). Its length determines the oil level in the transmission.
