Simon,
Had it serviced twice last year with no metallic particles in the pan. Surprising the oil when first drained was really good. Shifting into reverse is all good, it picks it up straight away. I have the miss VE SS auto I am driving at present, so driving that and then getting in the f truck, they are like worlds apart shift wise.
As for the oil, I have no idea!! I will quiz him prior to dropping it off. Might look at getting him to put the Nulon in.
