Hallole, have some questions about my Laguna 3, 2.0 dCi automatic, 173 hp, year 2011, 120.000 km: The change of the transmission oil is always controversially discussed. However, I had good experiences with the predecessor car (Laguna 2) with an oil change. Switching was simply softer after that etc. I bought the oil myself and had it changed at a free workshop. The drained dirt (originally gear oil) has removed all doubts, so if the nix brings, I know au nemme. Now to my questions: 1. Also recommended with the newer Laggi gear oil change? 2. What quantity is needed? 3. Certain brand or specification required? Thank you already in advance for your relevant notes! Greeting Dieter
