Transmission service on 99 psd

Just a heads up on the 99 with the recalled torque coverter it
does not have a drain plug . I replaced the filter an fluid but only
go eight quarts out of it so I guess I will have to take to the
dealer and get it flushed. Just a FYI the dealers I talked to
just flush the fluid and charge $150.00 so make shure you
tell them to change the filter or do it yourself and save money.

cobra......another trick some guys do is as long as the fluid doesnt ever smell burnt.......just drop your pan every 15k......change out the eight quarts...... and then just replace the filter every other time they dropp the pan........its not quite as effective as a flush....and i would probably still reccomend flushing it every 60k if your gonna use this method just to get it "all" every once in a while.......but its worth a thought......Marc

Torque Converter Flush the Dumb Outback Way....

Hello Folks,
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..

Best Regards from the Ranger in Oz...
