So just to double-check: You had the oil replaced as well and your gearbox did not blow up on the way home? Who would have thought?
Seriously though, I would appreciate feedback on your longer-term experience following the oil change. I am going to take my X5 for a gearbox oil change as well, despite all the "advice" that new oil is somehow bad for a gearbox.
Haha don't worry I've asked him the same question, he then took me and Chef to the back where all the gearbox recons are and he explained to us why and what happens when one does a gearbox flush on a gearbox that has some mileage on, the gears in the gearbox has a friction zone that has a shiny layer, when you doing a flush one actually removes the old oil from that gear and with the new oil that needs to get in there causes it to slip and so on (because of the gear that has some wear on it now), that's the reason why the only change the oil unless you do a gearbox recon then the will have to flush it, but then the gears will be reconed and the problems wont happen.
I've replaced the Sleeve kit, Sump, Gasket, Filter (comes with new pan) and then new oil has been put in - no flush just oil changed...
