Peugeot 307 gearbox slipping ABS fault
Summary of the thread
A 2003 Peugeot 307 is experiencing gearbox slipping and shifting issues, potentially linked to the ABS system, as diagnostic tools suggest consequential faults. The problem may be related to the vehicle being stuck in limp mode. A similar case was resolved by inspecting and resetting the ABS module, which temporarily resolved the issue without cost. Further monitoring is needed to ensure the problem does not recur.

Yes, I've pulled the diagnostic trouble codes. It's showing a powertrain malfunction alongside the ABS issues. The gear selector seems to be functioning mechanically. Were your diagnostic trouble codes similar? Did the initial ABS issues appear before the gearbox problems manifested?

I didn't delve too deeply into the diagnostic trouble codes myself, but the symptoms were almost identical: gearbox issues starting after the ABS light came on sometimes. Given the complexity, and without proper equipment, the best idea is probably going straight to the workshop.

Understood. Thanks for confirming. Good news: the eventual repair cost was 0€. Oddly enough, after a thorough inspection and reset of the ABS module, the issue seems to have resolved itself. We'll see if it returns.

Sounds familiar. I've got a 307 too. A while back, the gearbox started acting up in a similar way - slipping. I also noticed the traction control light was on intermittently. Did you check for any diagnostic trouble codes beyond the ABS?
