can you give me the location of the transmission oil filter on a 1998 honda accord 3.0L v6

 

It is inside the case, you would need to remove the trans and then open the case to access the strainer.
It is not a readily accessible component.
This is why it is critical to drain and refill the trans at the determined intervals, as the strainer can become impacted with debris and become blocked, rendering the trans starved of fluid and non-functional.
