For a 99 integra with automatic transmission, will fluid come out if I take out the passenger axle?

 

it probably wont if the car is not tilted. but it all varies

 

Im also about to replace my passenger side axle on an auto. Is the same concept as a manual transmission?

 

Should be the same. You can try lifting the front right corner of the car only to keep ATF from spilling out. Some may come out, but not as much as it would if both sides of the front end were lifted the same amount.

 

Yes
