On my 2003 Accord 4 cylinder there is a trans leak in the area of where the shift cable enters the trans. It may be running down on this area. What is in that area that is a common leak. In looking at the parts diagram of the shifter cable it doesn’t look like there is a transmission seal involved in that system

 

I"m guessing it's the drive shaft seal just above the shift cable. My 03 V6 looks like it's leaking from the same place. It's a very small amount, so I'm not even thinking about tearing it all apart to change it at this point. It's going to have to get worse.

 

It isn't a half shaft seal leaking

 

A quick look at parts drawings & I can't find the seal either, but there has to be one for whatever kind of lever that the shift cable attaches to.

 

Then where could it be coming from? The main seal?

 

There has to be a seal on the shaft coming out of the trans for the shift cable I am guessing. I would think that would be the valve body.
