MOT tests never open up a transmission, so this signal comes from the cross-market (xm) index: each model's share of transmission complaints and recalls, benchmarked against the average model's share. 1.0× is average; higher means owners report transmission trouble disproportionately often. It informs the outlook but never moves the MOT-based reliability grade.
