How do you check the transmission fluid in a 2006 VW Jetta? How oftain should the fluid b changed?

Fluid Level Check

Automatic Transaxle Differential Fluid
The manufacturer does not specify a maintenance interval for changing the differential oil/fluid. However, periodic inspection of the level of the fluid (and the fluid itself) is recommended. A high oil level indicates one of three conditions. First, the previous mechanic/owner may have accidentally overfilled the transaxle if the vehicle was not level. Secondly a high oil level (assuming the vehicle is level) can be caused by excessive condensation (water) in the differential. This may be a result of constant operation in wet areas, or high humidity. Moisture can condense inside of the transaxle in the same manner that a can of cold soda 'sweats' when removed from a refrigerator. Lastly, a high oil condition may indicate that the internal seals that separate the differential section from the torque converter/gearset are possibly faulty, and ATF has contaminated the differential oil.

NOTE Access to the fill/level plug is difficult with the vehicle on the ground. The vehicle must be level to ensure an accurate reading. Carefully raise and safely support the vehicle on jackstands in order to access the fill/level plug. Make sure the vehicle is level before completely removing the plug.

1. Park the vehicle on a level surface.
2. Raise and safely support the vehicle such that it is level.
3. Place a suitable drain receptacle underneath the rear of the transaxle.
4. Remove the filler plug on the side of the transaxle, near the halfshaft flange.
5. Note the oil level; it should be even with the lower edge of the filler hole.
6. If the oil level is low, add the proper type and viscosity as necessary to obtain the correct oil level.
7. Install the filler plug, and tighten it securely.
