1997 Isuzu Rodeo Question Where is the dipstick to check flu

Does not have a dip stick. On very level spot run for 3 min shifting through gears. Shut off slide under see tans pan two plugs one is higher up not the one in bottom of pan. Remove higher plug if fluid comes out it is full. Now the trick is that plug is also how you add ATF Dextron III dealer pumps it in maybe you could fashion a hose and funnel to get fluid in.
Good Luck
