Jenson Button handed five place grid penalty at Japan Gran Prix after unscheduled gearbox change on McLaren car

The 2009 world champion currently sits sixth in the standings, 75 points
adrift of Ferrari’s Fernando Alonso.

McLaren technical director Paddy Lowe told AUTOSPORT: “Jenson’s gearbox
had the same problem as Lewis’ gearbox during the Singapore Grand Prix, and
subsequent investigation has revealed a terminal failure.

“Therefore both cars must start the Japanese Grand Prix with new
gearboxes, which means that Jenson will receive a five-place penalty.”
