Torque Converter Flush the Dumb Outback Way....
I was not going to answer at first, a little embarrassed about it, but I can see how it might help others, and I think it works... I just did the fluid change over on my 2003 for a higher boiling point synthetic, and big surprise, did not get all the old Mercon fluid out??? Guessed converter... So, the Castrol Transmax Z is a different color (we spell it colour) than the Mercon, and I did the following experiment:
I had saved a 20 litre pail of Transmax Z, that was used but still good and appeared clean... So I put that in. I ran it through all the gears with the emergency brake on, reverse and all for a few minutes and dumped again. Then I started putting in new Transmax Z. I topped it off with new, ran through all the gears for a few minutes, and drained it. The second time it was just a tinge of pink. The third time no pink. To be sure I did it again, and there was no colour change. Even now 1000 km later, it still looks like new Castrol Transmax Z. Castrol Technical says they are compatible... What it looks like is that the converter flushes itself faster than I would have thought, maybe Marc knows, but it seems to work, so now one has to weigh up the cost of extra fluid vrs the Dealer flush... In my case, I think I was already committed, and it worked out cheaper anyway...
It appears you can flush the converter yourself, four changes, in my case three of new fluid, all up about an hour of play... Seems to work..
