Peugeot 4008 transmission control unit fault

Having issues with my 2016 Peugeot 4008, gasoline engine. Paddle shifters don't work, gearbox slips, grinding during gear changes, slow paddle shifter response, and gearbox goes into emergency mode. Error code points to the transmission control unit. Mileage is 107714 km. Think the control unit is the problem.

Whoa, sounds rough! I had something similar happen with my Peugeot (not a 4008 though). The paddle shifters went bonkers, and the whole shifting felt off. Is it throwing any warning lights?

Yes, a warning light is on. The error code indicates a fault within the transmission control unit. Did replacing your control unit resolve the issue?

Yep, replacing the control unit fixed it for me. Cost a pretty penny, though. I'd get it checked out by a workshop, they can confirm if it's the same issue.

Thanks for sharing your experience. I had the car diagnosed, and it was indeed the transmission control unit. The repair cost about 1000€. The issue is resolved.
