Red Bull Team boss Christian Horner has played down doubts Red Bull might be suffering a fundamental problem with its 2010 car.
Webber lost his front row preliminary place in Canada due to an unplanned gearbox change penalty, and his team-mate Sebastian Vettel completed the Montreal race with a gearbox trouble that prevented him from pushing to the limit.
Following the race Vettel insisted there was "no reason to panic" about the troubles and it has now emerged that he will use the same gearbox in Valencia, even though a change during the weekend will result in five-place grid penalty.
Christian Horner told Germany's Auto Bild: "They were both different problems. We do not have a fundamental problem with the car."
Red Bull is also hoping to get back ahead of McLaren in Valencia, having spent the past few weeks refining its F-duct.
"We expect some new parts and a step forward," said Vettel.
