FitFreak Family, after much searching with the search feature, and some browsing online through various parts sellers, I cannot figure out what this bolt is. It appears to be leaking a drop of oil every so often. Can anyone shed some insight?

 

I have no idea, but check here: https://www.hondapartsnow.com/page_p...=&partNumbers=

You can click on the left to choose the different parts of the transmission. I'm not sure which part of the transmission is where the transmission bolt is, but you should be able to find out what that mysterious bolt is from there.

Let us know when you figure it out!

 

Thank you for the response. I did check through all the various diagrams and could not find it. I even asked the Honda Parts desk, although they are not always the best source of information. The clerk pulled up the same microfiche (pdf, same ) and could not make heads or tails of it.

 

Hm. Well, I have been playing a game called Wrench, and when doing the transmission oil change job, it says to remove the drain bolt and then remove the fill plug, to help the transmission drain faster. I wonder if that mysterious bolt is the fill plug?

 

Not sure, but it looks like a bolt that helps hold the case together. It might not be the source of the leak. Leaking fluids tend to blow about everywhere under a vehicle making the source difficult to diagnose. I'd start my spraying degreaser under the whole area to get it clean, then when fluid starts to collect, wipe it with a white rag to see if you can determine by color and odor what it is.

The fluid could be engine oil if you have a leak in the seal that separates the engine and transmission. Keep an eye on your motor oil level for clues.

Is that black plate to the right easily removable? (manual transmission cars have these so as to be able to easily examine components; not sure about autos). If you have some time, you might take it off and look inside.

 

Looks to me like the leak is coming from above the bolt (dirty, wet area above it). Leak might be originating further up.

 

That is a possibility. The drain plug is observable to the right, but IIRC they were approximately at the same level. Although I can not rule it out completely, I do not think it is the fill plug. But, the leaking fluid does have a reddish tint to it, which is transmission fluid.

According to the PDFs I have seen online,it appears to be the crankcase cover. As I mentioned to StGemma, it had a slight reddish tint to it. So it could very well be transmission fluid.

It was hard to ascertain where exactly the leak was coming from as the car would only leak at high ambient temps while driving. Unfortunately, the fluid would spray around because of highway speeds.




Thank you all for your input. I had half a mind to simply remove the bolt and see what happened. I ended up donating the car soon after the discovery of the leak and moving on to something else. It was not entirely planned, as I had wanted to give the Fit to my nephew who was starting college in the fall, but I did not want to saddle him with a leaky car.
