Oddly the thread I started a while back about the transmission shudder disappeared. Little history at 50k I had my Tiguan at the dealer for another service and asked to have the Transmission serviced. They hinted it was unnecessary as it's supposed bto be a lifetime fill no service requirements for it. I am a firm believer that no fluid can last 100k miles. So they serviced it by dropping the fluid and refilling. (Soni thought). About a month ago I started exhibiting issues in the transmission, hard shifting, random shifting,. And wanting to drive in town at 35 mph and it would drop into 6th and Lock the torque converter so I'd be lugging around at 900 rpm making a ton of noise and shake. Driving in sport mode would help, but oddly when it would be in 6th I could manually down shift and it would usually pop into 3rd or 4th. Same with cruise. So I knew the computer knew what gear it wanted but the TCM thought otherwise due to pressures etc. No codes, all solenoids checked in fine.
So I ordered a service kit with fluid Shawng highly recommended readapted my DSG fill tool for the 09M. Pulled the drain plug and I had fluid gushing out. Stuck the 5mm Allen in to find the insert dip stick was loose. Even after snugging it up I still had a bit too much fluid coming out for the temperature. So I was over full??? So I pulled the insert totally drained the pan. Fluid didn't smell burnt so that's a huge win but it definitely smelt old . Well used for sure. Pulled the pan, and it was definitely well past due for Service. Magnets were covered and did their job. A bit of speckles in the fluid in the pan, and the filter screen and too was covered in a light grey film. All signs of old fluid. Cleaned up everything on the solvent tank. Cleaned up the magnets and stuck them back in installed the new filter, and gasket and followed the guide below to refill. I might of left it a bit over full as I got about 5.5 liters in and dropped a bit, but the fluid was pushing 45C when I did it.
Under the advisement of Shawng I'll probably drop the fluid again in a few thousand to get rid of more if the fluid.
Blauparts has a wonderful DIY guide for the 09M service. It's honestly not that hard. I built my own fill tube using fittings and a funnel. Pan threads are M10x1.0! Found a barbed fitting on Amazon. And went to work. It's a slow fill process as the insert is like a straw. Patience is key.
