Peugeot 2008 Automatic Transmission Shifting Issue

I had similar issues with my 2008. It felt like the transmission was slipping, like a worn-out clutch in a manual. Is the shifting rough, almost hesitating between gears? Have you checked the transmission fluid level or its condition?

Yes, the shifting is rough and hesitant, just like you said. I haven't checked the fluid level or condition yet. Where's the fill point, and is there a dipstick on this model?

On mine, the fill point needed special tools, and there wasn't a dipstick. Given your description, it's probably best to get it checked by a workshop for a diagnosis and maybe a transmission flush.

I took it to a workshop, and they confirmed the transmission oil was worn out. A flush and oil replacement fixed it. The total cost was 240€. Thanks for the help!
