According to owner's manual, ATF level should be at full/maximum mark when transmission is at operating temperature; OR 10mm (about 1/2") below minimum mark if at shop (i.e. room) temperature. So I check my level when cold and it's where it's supposed to be. But then I check when hot and it's 1/4" ABOVE full mark. And yes, I give it several minutes to settle down and cycle through R, D, and N.

I might have thought that 1/4" is nothing to be concerned about, but several much more knowlegeable than I have encouraged me to remove the excess.

What gives? Which of the two readings is likely to be more reliable?
