the last one is to drain the ATF, remove the torque converter, empty and rinse it, reinstall filled torque converter, clean out lines and ATF cooler, and refill the ATF.
Leading evidence: 'Fill torque converter' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Clean does only benefits the longevity' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

Also to take out the valve body and give it a good clean does only benefits the longevity.

#3 drain and fill with the amount of fluid you removed, and drain from transmission oil cooler output/return line and refill repeatedly until you see the new clean fluid.

If you notice the ATF stays very clean over time you can decide to make longer intervals.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I would like to
replace nearly 100% of the old fluid with new fluid, including fluid in the torque converter and oil cooler lines.
There are three ways to drain the fluid out as far as I know.
#1 using a flush machine. (personally, I don't want this method)
#2 drain and refill about three times from the oil pan. i.e. (
https://rennlist.com/forums/997-turb...nfusion-3.html
)
#3 drain and fill with the amount of fluid you removed, and drain from transmission oil cooler output/return line and refill repeatedly until you see the new clean fluid.
Which one do you prefer?
And, if I applied method #3, which location of the transmission oil cooler line should I disconnect to drain out with this 996?
And, "putting the gear selector into every gear position" means that I should select 1st-5th gears and reverse or P/R/D/N?
Flushing is one option, you mostly clean out all the old ATF
the other one is to drain and refill the ATF. You will have replaced half of the ATF. Repeat this 3-4 times and you will have substituted most of the old ATF with new.
the last one is to drain the ATF, remove the torque converter, empty and rinse it, reinstall filled torque converter, clean out lines and ATF cooler, and refill the ATF. A lot of work as you will need to remove the transmission. Which means probably dropping the engine in case of tiptronic car.
On a chevy you can drill a #8 screw hole in the appropriate spot on the torque converter
turn the hole to 6:00 and let it drain, then turn the hole to 4:00 and tig the hole shut.
Its as scary as it sounds the first time..
I gotta ask: why bother?
In my experience, just getting a new filter in there is a huge improvement. The fluid doesn't really degrade like engine oil. New filter, clean pan, change the fluid that comes out, and you're good to go.
Fluids degrade, no matter what!
Maintenance interval following workshop manual is 140.000km. I would advice to do it every 70.000km. On top of that depending on how hard you push the car maybe replace half of the fluid every 35.000-40.000km. (Sorry my Miles conversion is crap
If you notice the ATF stays very clean over time you can decide to make longer intervals.
It is not that difficult and it extends the longevity of the transmission. Especially for the ZF transmission in mk1 cars. The 722 type Mercedes transmission.in the mk2 and Turbo is rock solid and much more reliable mechanically.
Also to take out the valve body and give it a good clean does only benefits the longevity.
