Shifting/Engine Noise
 

- 2010 Honda Fit Sport M/T
- My shift point is consistently between 3200-3700 RPMS. If I shift & slow down, and the RPMS dips below 2100, and do a gradual speed up rather than downshift, my car makes a nasty noise. It sounds almost like metal-on-metal, but when I get over 2200 RPMS the noise completely stops and it only happens in gears 3-5. Any ideas?

It'll happen at all times no matter temp or if the car is hot/cold as well!

Wondering mostly if it's TCT/Timing Chain related. Been going on for over a year and I've had a friend who is a past Honda Tech say it's fine......starting to not fully believe the advice after his half-baked inspection.

Possibly a heat shield
 

I have that exact same sound on my fit. Does it sound like it is coming from under the car / back of the engine? I have tried to track that sound down to no avail, but to me it sounds exactly like my old car and its heat shield. I’m thinking that it only is under load at a lower RPM that it resonates with it.

the only problem is that I can’t be 100% because I haven’t truly found the culprit yet.

Try taping your exhaust with a rubber mallet. If it's the heat shield, you'll probably hear it doing so.

The sound I am having
 

This one might require some good headphones and a quiet place. But this is the sound that I am getting right around 2000 RPM.

I found an interesting video that might help in the situation

That video is your best bet for a rattle that sounds like its from the engine. Had the same issue on an automatic, the automatic transmissions also make noise when driving slow with dirty fluid, changeing the fluid a couple of times and a filter change rectifies this issue. Since you have a manual it's most likely the exhaust heat shield.
