2006 Estima gearbox query

[Estima75]

Hello, I own a 2006 V6 Estima with a 6 speed transmission with 85,000 km on the clock. I am planning to drive the vehicle from Melbourne to Queensland in a few weeks and wasn't sure whether I should have the transmission serviced beforehand as I have heard that these gearboxes are 'sealed for life'. Is anyone able to offer advice on whether I should get this done beforehand please? Thankyou

what you may be looking for is a transmission oil change, and a service for the whole car would be nice too, so, all oils/fluids/tyres are good for the long trip, of course the drivers need their breaks too ! So don't forget to keep your fluids up and rest up every 2 hours or however you feel comfortable with.

 

not sure what any other gearbox servicing could involve ? replacing grinding gears ?
