Hi, I have a Volkswagen Golf Mk7 1.8 TSI with the 09G automatic transmission, not DSG.
Recently while driving, the transmission randomly shifted into 3rd gear at around 20 km/h and it wouldn’t let me downshift. After that, when selecting Drive or Reverse, the car would kick/engage harshly. I scanned it and got code P2723, which seems to point to pressure control solenoid E / solenoid performance.
Would you recommend starting with a 09G transmission fluid and filter change, or should we test/replace the electrical pin/internal harness/solenoid E first? I don’t want to replace the whole valve body unless it’s actually confirmed bad.
Also, if we do the fluid service, I know it needs the correct VW G 055 540 A2 fluid and the level has to be set by transmission fluid temperature, not coolant temperature.
Can you let me know what you would diagnose first and what you recommend?
