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
