Followed the details from a forum post – went very smoothly. You will need 12qts of ATF fluid to do a complete flush.
Basically the process is
- Drain from the plug
- Drop the pan
- Drop the filter
- Install new filter
- Reinstall pan with new gasket
- Add about 4qts through the dipstick tube
- Disconnect the transmission fluid return line, attach hose to it
- Start the car, pump out a quart, add a quart
- Repeat until only new fluid is left.
