engine compression will provide resistance. if you don't feel anything like hard stop or grinding, there is not likely something in there.

What about that noise I heard is that normal?

 
Rep Power: 367

i never rotated the flywheel on my civic, so can't answer. maybe someone who have done will know.

Ok I was rewatching the video. Behind the teeth there's like a metal disk but its just not there for parts of the disk. Could that be the issue or is it supposed to be like that.

 
Rep Power: 367

manual or auto trans?

Auto trans

I don't get what I'm looking at. Could you possibly explain it. Also what could be loose or broken in there that I would need to take off the trans to find out what it is.

 
Rep Power: 367

sorry, forgot to say.
Upper one is the manual, so disregard

bottom assembly is the auto torque converter. Same as the clutch in the manual trans, connecting engine to trans.
I was answering about the disk behind the flywheel.

we have not even found out if it is in the flywheel case or in the trans itself, so can't say what it is.
there's also the possibility that it is not there either, someplace else... That's the life of mechanics...

Ohhh ok I see. So what's my plan of action now, should I just go ahead and pull the trans?
Haha life of a mechanic, sounds fun.

before you go tearing down, read the last post on this thread. Recent thread with info that was not in the forums before.

Yup just read it. Sorta understood but I'm not sure if I have some of the things he does in his car or transmission. What I'm getting from it is to spray brake fluid into the trans and hope it clears it up? Also didn't understand what he said about the metallic filter or whatever. Although I will try.

 
Rep Power: 367

no, i meant, check if issue is similar to yours, if not no need to try

 
Rep Power: 0

I'm not sure if we have the same issue. His is a loud whine, but mine is like a loud grind. He did mention a loud grinding though. Won't hurt to try. There's a filter in the trans?

 
Rep Power: 367

yes, the usual main culprit for failing auto trans.
We have a separate section for that for the 7th gen for the frequent incidence of failing trans.

keep in mind that your issue is not common, so we don't know what is going on on your case.We are in the same boat as far as knowing the cause

Is the filter internal? Is it a possibility that I can remove the filter and replace or clean it?

If you want to pull the trans and split the case....

Sounds great! Ill break open the trans today! That's a joke btw. I've got some brake cleaner anc I'll attempt to drain and clean the filter. Where would it be? Also, I don't have any spare trans fluid so is it ok to filter and put it back in to test?

 
Rep Power: 222

No!
Trans fluid is cheap

Got some oem fluid ordered and it's on its way. Uh so I may have lost a small tube into the opening of the transmission. And it's seemed to have disappeared. Should I be worried about that, cuz I'm pretty worried about it. To be clear I lot a small straw into the transmission fill area. I am not the brightest.

Just an update, but I did a compression check to see what is going on after finding out the car won't even start anymore. Here's how the test went. First had 154, second had 200, third had 153, and fourth had 155. Is one of them supposed to have such high compression? Starting to think it's engine related now. When I pulled spark plugs to check, the plugs were black. But these are new plugs. Also it smelled like oil mixed with gas. There was small gunk on some of the plugs too. I do not have any luck with cars.

Well. It's the end boys. The noise turned out to be from the engine, not the trans. It was a rod knock. It went from that noise to a rod knock. In the 3rd cylinder. Well she's sold now. So I won't be around here anymore. The car was fun while it lasted. Maybe I'll get another cheap civic and just take everything apart to learn more.

Sorry to hear that. Just curious, did it ever overheat? If oil gets too hot it stops lubricating and can cause spun bearings and rod knock. I've bought a few Civics with rod knocks that were caused by bad head gaskets that were neglected.

 
Rep Power: 0

Spun bearing or a worn out one. Im guessing it's the first. No, there were no signs of a head gasket failure. Didn't overheat or blow smoke out the back

D17’s don’t show typical signs of head gasket failure. Your coolant reservoir would be gaining coolant, even possibly overflowing.

Don't have the car anymore, but when I was still diagnosing the issue, the coolant seemed alright. The resevour and seemed normal and it wasn't overflowing.
