2005 Lexus LS430 six speed transmission fluid and filter change at 128k mile. Never been done

These torque specs are my best guess. Do you own research. These are what I found. Always use new crush washers. (always check with Lexus dealer using car VIN). If you are not sure, don’t do anything. Find a qualified mechanic
