Until 12/94
Note: Since 12/94, it is no longer necessary to check the oil level as part of maintenance for vehicles with the "01M" automatic transmission. The oil must be changed every 60,000 km. Since this requires interrogating the transmission fault code memory, this work should be entrusted to a specialist workshop.
Examination
Ensuring the prescribed oil level for the automatic transmission is extremely important. Therefore, this work must be carried out with great care once a year.
Warm up the gearbox to operating temperature. The oil temperature in the gearbox should be approximately +60°C. This condition is reached after approximately 10 km of driving.
Place the unloaded vehicle on a level surface.
Place the automatic transmission control lever in position "P" (parking), apply the parking brake.

When checking, leave the engine running in idle mode.
The oil level indicator is located in the engine compartment. This is also where the transmission oil (ATF) is poured. Pull out the oil level indicator and wipe it with a clean, lint-free cloth, or better yet, leather. After that, completely immerse the oil level indicator, pull it out again and read the reading.
When the gearbox oil is warm (approximately +60°C), the fluid level should be between the "MAX" and "MIN" marks on the level indicator.
Check the oil on the indicator for appearance and smell. A burning smell indicates burnt friction linings. If the oil is contaminated, malfunctions in the automatic transmission control may occur.
Top up the oil level if necessary. Use only factory approved automatic transmission fluid (ATF) labeled "Dexron". All approved oils may be mixed. Do not use any additives to the oil.
Caution: Do not add too much oil. Excess oil may cause malfunctions in the automatic transmission. In any case, excess oil must be drained or sucked out with a syringe.
Oil change
Automatic transmission oil is normally changed every 60,000 km. We recommend that this work be done at a VW PASSAT repair shop. The engine must not be started if there is no oil (ATF) in the gearbox. Towing the vehicle is also not allowed.
Remove the transmission pan and the mesh oil filter on top of the pan.
Attention: used oil must be disposed of at a special collection point for waste fuels and lubricants.
Clean the oil pan with a clean, lint-free cloth.
Attention: When carrying out all work, it is necessary to maintain impeccable cleanliness, as even minor contamination can lead to gearbox failure.
Attach a new seal to the new mesh filter.
Attach spacers to the new oil pan gasket.
Install the mesh oil filter and tighten the mounting bolts to 8 Nm.
Screw on the oil pan and tighten the mounting bolts evenly to a torque of 10 Nm.
Check if the oil filter is installed. If the filter is installed, see the subsection "Changing the oil filter" below.
After this, pour 3.0 liters of automatic transmission fluid (ATF) into the hole for the level indicator using a funnel with an extension hose.
Please note: Only ATF oils with the additional designation "Dexron" may be used.
Start the engine. With the engine idling, with the automatic transmission control lever in the "P" position and the parking brake engaged, check the oil level with the dipstick. When the engine is cold, the oil should be filled to the +20°C mark, see Figure 37-823.
Warm up the gearbox and check the oil level, see subsection "Checking".
Replacing the oil filter
Previously, automatic transmissions were equipped with an oil filter, which is no longer necessary. This filter has now been replaced by an insert (spare part number VW096498067), consisting of a hollow bolt and a circular sealing ring that closes the opening intended for the filter.
Remove oil filter "1". To do this, place a rag around the filter and loosen it slightly using the filter removal tape. Wait a little until the oil drains from the filter, then unscrew it completely.
Using pliers, unscrew the filter bolt "2".
Seal the hole (arrow) with a hollow bolt and a circular sealing ring.
Tighten the hollow bolt to 40 Nm.
Warm up the engine and check the gearbox for leaks.
