Wrong transmission fluid 722.6 need guidance
second option would be to let a workshop flush it completely with a machine?
third option was to pull the plug in the bottom and also pull the torque converter plug and that would empty about 70-80% of the fluid?
Also the transmission fluid was exchanged 2 years ago with gasket and filters. would thoose need to be exchanged again because of the wrong oil?

You have the transmission dipstick correct/filler pipe correct?
Manual says basically drain the fluid, remove pan and replace the filter, reinstall the pan.
Remove the right side cooling line on the transmission and connect it to a hose to allow fluid to drain into a bucket. using the filler pipe add 5 quarts fluid, run engine until 3 quarts fluid are drained out the hose, shut off engine, add 3 more quarts, repeat.
