Mini Cooper S 2006. Trans fluid

Wolfs Head is a good brand. And you have to drop the trany pan unless there is a drain plug. You can get a drain pan with a plug.

There is a drain plug but the auto trans is different and only a small amount comes out, then the overflow pipe has to come out too but it still leaves a lot in the pan.

Wolfs head is not the recommended trans fluid but may be ok, your call. Can't drain all the fluid without dropping the pan (real pain in the butt) but you can drain about 3 liters and replace it by pumping new up thru the bottom. Need the right tools to do it otherwise it's really messy
