Jumper Automatic Transmission Torque Converter Issue

I had similar symptoms on my Jumper. Check the torque converter; that was the root of my problems.

Could you elaborate on the specific issues you encountered with your torque converter? Were the symptoms identical, and did a diagnostic scan confirm the torque converter as the source?

Yes, the symptoms were pretty much the same, including the error code. Replacing the torque converter fixed it, but it's best to get it checked at a workshop to be sure.

Took it to a workshop, and they confirmed the defective automatic transmission converter needs replacing. Repair cost is about 2120€. Thanks for sharing your experience; it helped during the diagnosis.
