Hi guys, plan to do a transmission sump and oil change at weekend, does any body have any tips, or procedures to follow.
any help would be greatly appreciated.

Getting the trans sump off is supposed to be a pain on the petrol models, don't know about the diesel models.
I got a gearbox flush last week done by disco mikey on here because you cant get all the gearbox fluid out when doing it through a sump change. A gearbox flush pretty much gets most of the old oil out. Hope this helps. 2006 4.2 Supercharged Buckingham blue

Im having a go due to not being able to get any one to do a flush locally at the moment.
