Check ATF with the engine off??
 

I RTFM and thats what it says...

I've always checked ATF with the engine running?
I bought this 98 Accord coupe EX V6 105,000 miles about a year ago.
Is this a honda thing or something new.
I want to check the manual on my Avalon when I get home tonight.

Trannys feeling a little funny and we are considering either changing the
fluid myself. (we just bought fluid from honda) or taking it to a shop to
have it "serviced".

Probably change it this weekend and see what happens.
