Would you recommend doing a drain, filling it back up & driving for say 1,000 miles or so before repeating the process. Or, would you just advise draining & filling all on the same day until the fluid becomes its original colour?
I understand that you can only get around 3L out of the transmission at a time via the sump, due to fluid being trapped within the internals.
I'm going to get one of the 20L drums on Ebay made my Mannol, as that'll do both vehicles.

When you drain, circulate for 2 mins then do again it does not mix the fluids. I have experimented with it.
Drain, then drive 200 miles and redo.
