Hey everyone, new member here. Just picked up an 08 Civic DX from my sister to use as a commuter. The car seems to be pretty tight other than a little rust underneath. I had it up on a hoist last week at a friends show for its safety inspection. Everything looked good other than a little oily residue which I thought may be power steering fluid. 2 days later on the highway it through a CEL and would not rev past a certain point. This happened a couple KM from my house so I pulled it in my driveway.
Once I got it up on a jack I noticed it seemed like tranny fluid. It’s only leaking when running. I’m not quite sure where it’s coming from. It looked like it was coming from a bolt but it seems it’s running down onto the bolt head from somewhere else. I didn’t have a proper floor jack and stands so I could not get under very well. I did take a bunch of pics but the cross member is in the way of getting a good look. The pics are from the front end looking towards the rear. Could it be coming from a trans Cooler line or another source?

Thanks for the reply, I will try to get it on jack stands and check around. What I’d really like is a picture or diagram that details the parts a little better. I didn’t find the Honda parts diagram helped much. Where do I look for the lines and cooler?

Thanks for that. I have seen that diagram already, I’m not quite sure the orientation of the picture. I know nothing about working on Honda, just Subaru. I borrowed a friends floor jack and stands and just got it up. Jack will not get it up high so it’s hard to have any room underneath. I’d like to get it higher and run it to see closer where it’s leaking. It’s coated pretty good underneath. I just sprayed a bunch of brake clean to try and clean it off. One axle is coated, the other side is not. I really need to figure out where the parts are on the tranny.

So I pulled the airbox to take a better look.
Seems it’s leaking from the area of the tranny filter and lines and leaking down the back of the tranny.
Any idea what I need to remove to access the area, inspect and replace?

Thanks for your help. That was my plan. The bolt holding the filter bracket is proving pretty difficult to get off. I will spray some penetrate fluid on it. The bolt head is rusty and rounding. Maybe vice grips will turn it.

Got the filter and hoses out. Seems like the filter is leaking. Ordered a new filter and hoses. Thanks again for the help.
