Well I've been contacting local-ish transmission specialists to see if anyone can offer a full flush service rather than a basic drain and fill. The people I've spoken to so far can't do the former. One company (TES transmissions in Wiltshire) said it's not possible to fully flush the system due to the design (solenoids, torque converter etc.) Surely the process of gear selection will ensure full flushing of the transmission?
Then there's the discussion of what fluid to use. . . . Lifeguard 5, esso, mobil, imported fluid from Canada (as used by Chester)? Both esso and Mobil are owned by ExxonMobil so I would guess both products are the same. I'm inclined to use ZF's own product for piece of mind (even though it is almost twice the price) but transmission specialists would be happy to use something else. . . .
It's amazing how much info is on this subject on the net with seemingly no clear answers. Maybe a call to ZF will be able to shed some light on the situation. After all they are the ones who designed the transmission in the first place.
