What size is the automatic transmission cooler hose?

Just as title says, im planning to do a A/T flush this weekend, and looking under there, the hose looks pretty chewed up, so I would like to replace it. Its important that the ID is correct as there is an inline check valve that needs to be swapped over. You can see it in the 2nd gen writeup.

 

3/8ths. Ive never seen a tranny cooler setup on passenger vehicles that wasn't 3/8ths. anywhere from civics to f250s. even their power steering lines are 3/8ths. 1 ton trucks will usually upgrade the setups to use 9/16 or 1/2 inch hose.

 

Thank you. I went hose searching today, it looks like 3/8in it is.
