Looking in the service schedule, there is no mention of changing the gearbox oil for the Bravo. Is it necessary to change it, if so, how often....does anyone know? Ours is coming up for its 124k mile service in the next 3 weeks or so.

its one of those 'for life' jobs with no specific service schedule stated/ required

however i would recommend draining and refilling with something of the right grade and a good brand like motul, i used this on my Cinq Sporting and it has taken 100k of abuse of tracks and still on original box

Hmmm just checked the service sheet and yeah your right it on there at all...

but i would have said 124k is more than enough reason to change it... go on treat your bravo! it certainly cannot hurt to change it.
