Bipper Automatic Transmission Problems

I've seen issues like that on the Bipper. Before jumping to conclusions about undervoltage, have you checked the automatic transmission oil? Those symptoms often point to worn-out oil. When was the last time it was replaced?

Thanks for the reply! I haven't actually checked the transmission oil. Honestly, I didn't even know it needed replacing. How often should it be done, and is it something I can do myself, or is it best left to a professional?

Given the symptoms you describe, and especially with that mileage, I highly recommend having the transmission oil checked and likely replaced by a qualified workshop. It's a delicate procedure, and incorrect oil or levels can cause further damage. It is probable that the worn out oil is the primary cause of your issue. It was the case for me.

Okay, thanks for the advice. I took it to the workshop, and you were spot on. The transmission oil was indeed worn out. They replaced it, and it cost me 240€. Seems to have fixed the problem. Shifts smoothly now. Appreciate the help!
