ND2 gearbox oil and service schedule

[Shinyfings]

Hi My ND2 had its fifth service at a main dealer (69 plate, 27k miles). I still use them as they’ve been good at getting warranty repair work sorted and also have managed not to damage the car in their care. The 5th service according to the on-line Mazda manual suggests the gearbox oil is changed. This hasn’t been done (nor did they say they would change it). As any main dealer would usually try and charge for anything vaguely required I’m assuming the on-line manual may not be entirely accurate. I’m interested as of course the gearbox is one of the weak areas. Has anyone had a 5th service at a main dealer and was the gearbox included/does anyone know if this is a requirement/suggestion etc.

Hi Thanks for the reply - yes manual. The dealer says 10 years. Mazda's on-line user guide says 5 years. The internet says 5 years. The car/gearbox is fine with the usual clunky shift in freezing conditions until warm. My only concern is that the gearbox is an ND weakness (according to various owner sites) so it'd be great to get a clear cut answer. I'll probably just change it but it's odd that there is no clear answer and that the Mazda dealer and Mazda's documentation contradict each other.
