Driver side back by the firewall look down you will see a small dipstick put a funnel in where the dipstick is and pour slow adding only enough to make it full Do not put it in the passenger side where the transfer case is
Unfortunately, you need to pour the transmission fluid into the dipstick hole. Found in Subaru owners manual
You add fluid the same place you check the fluid level.
Unless you have a LEAK you shouldn't have to add automatic transmission fluid on a regular basis
It usually goes in where the dipstick for the transmission is.
Check the automatic transmission fluid level. If it is low add enough to reach the full mark. If it is not low seek professional help. If you have to add fluid use only Genuine Honda automatic transmission fluid. Use no substitute.
Get a lube shop to do it.
4 quarts
If it is an automatic transmission, you add transmission fluid with a long funnel through the dipstick opening.
Through the dipstick tube--Do Not overfill
Add automatic transmission fluid through the dip stick tube. No kidding!
