Transmission flush ?

[XWrench3]

so I have my Liberty up on jack stands, changing the transmission fluid and filter. is there a way to flush the torque converter and oil cooler ? I guess I could just disconnect the cooler lines and use compressed air to push the fluid from the cooler. but that still leaves quarts of fluid in the converter. that I would really like to get out of the system.

Not positive about modern transmissions but there's usually a drain plug on the torque converters. Accessible the same way you'd get to the flexplate bolts.

Most just do a pan drop with filter, gasket, & ATF+4. That gets most of it fresh again anyways.
The safe & complete way of doing a trans flush is by a dealer re-circulating machine.

Pretty sure the KJ does not have a drain on the torque converter.

If youre worried about it, just drop the pan again at the next engine oil change.

add a drain valve to the pan too

I did add a drain to the pan. i always do. maybe if the factory added a $1.15 drain to the pans on every automatic they built, people might change the fluid/filter like they should. and no, i doubt there is a drain on the converter. but i really don't know. i couldn't see a way to access the converter. the older automatic's had a stamped steel access panel so you could at least tighten the torque converter bolts if they worked loose. but this appears like there is no access at all, which makes me wonder how they put these together at the factory. i have however, been accused of being blind before, so maybe i just missed it someplace. anyway, it took me 3 days (6-9 hours each day) to change all of the driveline fluids. getting old and broken up makes this stuff challenging to say the least. i took it around the block to make sure it still works, but the test drive will have to wait till tomorrow.
