McLaren have opted to start both Jenson Button and Lewis Hamilton with new gearboxes at the Japanese Grand Prix.
The Woking squad have taken the precautionary measure after an investigation found that Button's gearbox had the same problems which forced his team-mate out of the Singapore GP a fortnight ago.
The decision means Button will drop five places on the grid for changing his gearbox while Hamilton will not receive a penalty as he retired at the Marina Bay Street Circuit.
"Jenson's gearbox had the same problem as Lewis's gearbox during the Singapore Grand Prix, and subsequent investigation has revealed a terminal failure," technical director Paddy Lowe told Autosport.
"Therefore both cars must start the Japanese Grand Prix with new gearboxes, which means that Jenson will receive a five-place penalty."
