How Do I Check VW Jetta Aisin Transmission Fluid Level and/or Top Off The VW Golf ATF?
Once the VW Jetta automatic transmission fluid service is finished, the transmission fluid level need to be confirmed and possibly topped off. Checking the transmission level is done with diagnostic software and through a level insert tube a few inches long mounted into the fill plug / port. Diagnostic software allows you to accurately and simultaneously check the transmission fluid temperature and corresponding VW Jetta ATF level. When the transmission fluid is between a certain temperature a small amount of fluid will flow from the level insert fill port area.
