McLaren driver Lewis Hamilton will drop five places on the grid tomorrow for the F1 2010 Japanese Grand Prix at Suzuka after his team was forced to make a gearbox change.
Hamilton, who has crashed out of the last two races, has had a dismal weekend so far and has only completed a limited number of laps following an off in opening practice on Friday.
He was also unable to make up time today due to heavy rain, which meant FP3 was a washout, while qualifying was postponed until tomorrow morning.
"In P3 today, we noticed abnormal gearbox oil pressure on Lewis's car which we believed we had corrected ahead of this afternoon's qualifying session," read a statement from McLaren on Reuters
"This afternoon, as we fired up Lewis's car several times in preparation for qualifying, we became aware that the symptoms were worse than we'd originally diagnosed.
"A decision was later taken to change the gearbox ahead of tomorrow's qualifying session and the grand prix. As a result, Lewis will receive a five-place grid penalty for tomorrow's race."
Hamilton is currently third in the race for the 2010 drivers' title - 20 points behind Mark Webber.
