Change the oil winged box

CHANGE THE BOX AL OIL BUT THE ALANTE CAP

If I remember correctly, in the Megane that screw assembles the selector internally, like in the Volkswagen. Take it to someone who repairs gearboxes because we're talking about a manual gearbox, right?

No, friend, the transmission is automatic. Now it does this: when I start the car, it engages, moves forward but weakly, and then goes back to neutral. Could it be the type of oil I'm using? It was PDV D3. I'm Venezuelan. Or could it be a clogged filter or the oil level? What could it be?

Okay, it's clearer now. It could be the type of oil, and a clogged filter could also be a factor. But before you changed the oil, was the car moving? Because if it was, it might have too little oil or the wrong type

Friend, I bought the Merco 4, is that the same one inside 4, and the car is still the same. The car was running fine, the issue is that when they removed that plug that holds the selector, supposedly it was fine, but does that valve body have some adjustment that it might have lost? I put 3 liters into the transmission
