What is the VW transmission fluid change interval for Aisin transmissions?
How often should Aisin VW Jetta, Passat, CC, Golf, Tiguan, Beetle, or Rabbit transmission fluid be changed? The recommended service interval for changing the VW transmission fluid on Aisin transmissions is every 50,000 miles - 60,000 miles. Those with more aggressive driving styles, constant extreme heat, heavy city traffic, trailer pulling, or other severe driving conditions may want to replace the VW transmission fluid sooner. Changing your 6 speed VW Aisin transmission fluid is important and helps extend the life of your transmission.

How To Step 1
Place the vehicle level on an approved automotive lift or jack stands using factory lift points and procedures.
How To Step 2
Begin by removing the lower engine splash pan. This is held in place by several T-25 torx bit screw.
How To Step 3
Locate, loosen, and remove the VW transmission pan drain plug allowing the Jetta, Passat, CC, Golf, Tiguan, Beetle, or Rabbit ATF to drain into a suitable waste oil drain pan. This is a 5mm Allen drain plug.
How To Step 4
Once the transmission pan drain plug has been removed you will need to locate the drain plug fluid level insert. This is recessed up inside the transmission pan drain plug port. The drain plug level insert is a 5mm Allen. As you are removing the drain plug level insert you will allow the remaining Jetta, Passat, CC, Golf, Tiguan, Beetle, or Rabbit ATF to drain from the transmission pan into a suitable waste oil drain pan. Once the fluid has drained, reinstall the drain plug. This will minimize fluid spillage during pan removal and cleaning.
How To Step 5
Remove the transmission pan. This is held in place by 10mm bolts. Begin by loosening all the transmission pan bolts. Once all the bolts are loose, remove all the bolts except two at opposite ends of the transmission pan. Lastly, remove the two bolts left well supporting the pan. In most cases there will be a small amount of Jetta, Passat, CC, Golf, Tiguan, Beetle, and Rabbit transmission fluid (aka VW ATF) still left in the pan. 09G style trans pan has 8 bolts total. The 09M style trans pan has 9 bolts total.
How To Step 6
Remove the VW transmission filter. This is held in place by three - 10mm bolts. Throughout the era of the VW 09G and 09M automatic transmissions several transmission filter styles were used. Slight variations will exist in the filters to what is depicted in the images. However, the steps and procedures in the instruction still apply.
How To Step 7
Remove the old rubber transmission pan gasket from the transmission pan.
How To Step 8
Clean the transmission pan and pan magnets of all dirty VW Jetta, Passat, CC, Golf, Tiguan, Beetle, or Rabbit ATF and sediment. The magnets are in the transmission pan. Always note the transmission pan magnet locations and return them to the original location after cleaning. This is best done with lint free rags, a parts washer, or brake cleaner.
How To Step 9
Clean the VW transmission pan gasket mating surfaces on both the transmission side and the pan side. Make sure to remove all old gasket material and corrosive buildup. Be careful not to dirty any of the transmission internals and only use lint free rags.
How To Step 10
The 09G, 09M transmission filter seals to the transmission by a rubber or cork material which could leave buildup. It is good to check for this build up and clean these gasket mating surfaces to allow for a proper seal of the new VW Jetta, Passat, CC, Golf, Tiguan, Beetle, or Rabbit transmission filter. If a good seal is not made, this could cause transmission reliability and longevity problems. Be careful not to dirty any of the transmission internals and use lint free rags.
How To Step 11
Install the new VW transmission filter and evenly torque the three – 10mm mounting bolts to 7 ft. lbs.
How To Step 12
On a clean bench top insert the transmission pan gasket spacers into the gasket.
How To Step 13
Install the transmission pan gasket onto the transmission pan, closely aligning the mounting holes.
How To Step 14
Reinstall the VW Jetta, Passat, CC, Golf, Tiguan, Beetle, or Rabbit transmission pan with gasket onto the transmission. Align the transmission pan mounting holes and install the 10mm mount bolts. First tighten the mounting bolts evenly to a hand tight torque. Next evenly tighten the transmission pan from one side of the transmission pan to the other, torquing the bolts to 7 ft. lbs.
How To Step 15
Reinstall the transmission fluid level insert, using a 5mm Allen into the drain plug port. Leave insert snug and do not over tighten as this is made of plastic.
Aisin VW Jetta, Passat, CC, Golf, Tiguan, Beetle, or Rabbit Transmission Fluid Filling Procedure:
How To Step 16
Hand tighten the fill adapter onto the VW transmission pan. Once the fill adapter is installed, slide the fill hose on as pictured.
How To Step 17
Slide the loose end of the fill hose up in front of the transmission and connect it to the fluid bottles as described in the supplied instructions. Connect the hose to the VW ATF bottle as described in the supplied instructions.
How To Step 18
With the vehicle in a level and elevated position allow around 2.5 liters of ATF to flow by gravity or pumped into the transmission.
- As fluid is being fed into the transmission start the vehicle.
- With the brakes applied, shift/select through all the gears of the transmission while the engine is idling. Allow 3-5 seconds for each gear selection.
- With the transmission back in park and the engine at idling, continue to gravity feed or pumping the remaining 2-3 liters of new ATF into the transmission.
- Once all 5.5 - 6 liters have been pumped into the transmission and the engine still at idle quickly remove the fill adapter tool, and install the drain plug. Tighten the drain plug enough to minimize a leak.
Why do we supply 6 liters of ATF in this transmission service kit?
We supply 6 liters of ATF for this application to ensure all customer have an adequate amount of ATF on hand for all ATF changing scenarios.
Typically draining the transmission fluid, lowering the transmission pan, and replace the transmission filter will allow around 5 - 6 liters to drain from the transmission. The remaining 1 - 2 liters are in the torque converter, transmission cooler lines, and transmission cooler. Some customers allow a longer duration (siting overnight) to pass while changing the transmission filter and ATF. At times this allows another 0.5 - 1 liter to drain from random internal areas of the transmission. Others choose to drain the ATF during excessive transmission temperatures, loosen transmission cooler lines to remove more ATF from the transmission cooler related areas, and other alternative techniques.
Our kit contains 6 liters of ATF for all average ATF fluid and filter change situations. This provides most customers an adequate amount of ATF while filling and fluid level checking the transmission. We also recommend having an extra liter in case a customer spills and would not typically have enough ATF on hand to complete the service.
Also, many individuals and automotive service facilities choose to drain the ATF into a measuring pan and will only pump the same amount of ATF back into the transmission as was removed. This is not the correct filling process and will yield an incorrect fluid level. We encourage all to use the recommend transmission fluid temperature leveling sequence. Bringing the ATF along with the transmission up to operating temperature together from cold allows for the most accurate ATF level and transmission shifting characteristics.
If you desire a more thorough ATF flush, we recommend driving the vehicle for 5-10 minutes and then performing a 2nd ATF drain, fill, and ATF leveling procedure with another 4 liters of ATF. This should allow the majority of harshly contaminated ATF to be removed from the transmission.
(To allow for a quicker flow of ATF into the transmission you may use ATF pump tool number J91001 as described below.)
Blauparts’ Transmission Fluid Fill Pump Tool Alternative
J91001 Instructional Document that shows how to adapt the pump to the Ravenol bottle spout tube. The hand pump base can be adapter directly to the Ravenol bottle tube that pulls out from the Ravenol bottle cap. As the fluid is pumped into the transmission, the bottle will collapse as the fluid is sucked from it. This may not be the prettiest way to pump fluid into the transmission, but it is an adequate and cost-effective way to fill the fluid, rather than having to buy the more expensive and .
How To Step 19
As the engine is at idle. Plug the Ross-Tech diagnostic software into the OBD2 port and begin to monitor the transmission fluid temperature.
Using the Ross-Tech:
- (1st) Select Control Module
- (2nd) 02-Auto Trans Control Module
- (3rd) Measuring Blocks – 08
- (4th) Group 006.
Display group 006 in field 1 will allow for an accurate ATF temperature reading.
How To Step 20
With the vehicle level, bring the transmission fluid temperature to warm between 35°C - 45C° (95°F –113°F). At this temperature range, you can remove the transmission drain plug and transmission fluid should begin to flow out from the fill port level insert. When this happens, the proper ATF fluid level has been achieved. The ATF fluid level is correct when the transmission fluid transitions from a consistent stream into its very first drip between the fluid temps of 35°C - 45C° (95°F –113°F).
Side Note: Do not allow the transmission temperature to exceed 45C° (113°F). Reinstall the 14mm hex bit drain plug before the transmission fluid temperature exceeds 45C° (113°F).
Side Note: If no fluid drips from the fill port between the temperatures of 35°C - 45C° (95°F – 113°F), proper level has not been achieved. Reinstall the 14mm hex bit drain plug, turn off the engine, and allow the transmission to cool to below 30°C (86°F). Repeat the transmission fluid level process per the above recommended steps 19 - 20.
How To Step 21
Reinstall the 5mm Allen drain plug and torque to 12 ft. lbs.
How To Step 22
Once the proper VW Jetta, Passat, CC, Golf, Tiguan, Beetle, or Rabbit transmission fluid level has been attained, turn the engine off and exit the Ross-Tech diagnostic software and disconnect the OBD2 plug port.
How To Step 23
If you do not have a Ross-Tech diagnostic software available to you for reading the internal transmission fluid temperature you can use any diagnostic software that can access and read the internal transmission fluid temperature. The most accurate transmission fluid level and temperature reading is achieved using diagnostic software.
However, if you do not have diagnostic software, you may wish to use other options to read the transmission fluid temperature. One alternative is an infrared thermometer - See Image. Typically, an infrared thermometer reads within a 4° to 5° degree difference when compared to diagnostic software which measure the true internal transmission fluid temperature. Thus, an infrared thermometer can be a reliable temperature source when performing the transmission fluid leveling sequence. If an infrared thermometer is used it is best to allow the fluid temperature and level reading to be more towards the low side of the temperature window of 35°C - 45C° (95°F –113°F). For example, a 34°C reading will be closer to a 38-39°C internal fluid temperature reading.
How To Step 24
Re-install the lower engine splash pan with T-25 torx.
How To Step 25
Remove the vehicle from the approved automotive lift or jack stands using factory lift points and procedures.
