Berlingo Automatic Transmission Converter Fault

Your description does indeed sound concerning, and the error code is quite telling. Could you elaborate on the conditions when you experience the slipping and grinding? Does it occur at specific speeds or during particular driving maneuvers, such as acceleration or deceleration? It is critical that you provide any additional information regarding the error code, such as the precise code number, which may assist in determining the precise nature of the torque converter issue.

As for the slipping, it mainly seems to happen when I'm trying to accelerate onto the highway, especially around 50-60 mph. The grinding noise is more random, but often present when shifting from 2nd to 3rd gear. I can get the error code number to you later, once I get home.

Based on your description, I strongly suspect a failure within the torque converter itself, specifically the lock-up clutch mechanism. The symptoms you are experiencing are typical of this specific issue. As the torque converter is a crucial component of the automatic transmission, I would highly recommend that you seek expert assessment from a qualified transmission specialist or a certified mechanic without delay. Continued operation with a faulty torque converter can lead to further damage and significantly increase the overall repair costs. I must recommend against attempting any self-repairs in this situation.

Thanks a lot for the advice. I took it to a shop and you were spot on, converter fault confirmed. Ended up costing me 2120€ to get it sorted. Ouch! But at least it's running smoothly now.
