Hi there

I have a Honda civic 2006 EX 5 speed transmission.
Just recently I reached 75000 Km's on the vehicle,so far everything seems ok.

I am going to try to explain this the best I can.I first notice that in the early morning starts.... I start driving..i shift to second and as i shift i hear a high pitch noise when shifting and even when rpms go 2000-4000rpms.
I go in to third gear same thing as soon as i accelerate , shift i hear the high pitch noise whether i shift to second or third or forth the high pitch sounds appear...it last for about between 2-4 minutes of driving.
Now it does not only start in the morning..now if its mid day or night i start the car and drive and shift this happens again and it only last a couple of minutes.I want to bring this in the for service but Honda saids they can diagnose this if this does not happen when they inspect it and i can just go into any honda service centre when the sounds appear...any suggestions would be appreciated...thanks everyone

 

Never heard of it but I would say take it to your dealer.

 

is like a high pitched whining or whistle or is it a whirring sound like the engine. If I have the radio off I can hear the engine and when you get to 3 or 4k right before you shift the engine tone is pretty high pitched.

 

yes ..do you know why..thanks

 

do you have an aftermarket stereo equipment?

 

no i have stock radio...any suggestions why..thanks

 

no even with stock audio it does that. it's an annoying whistling sound that whenever u shift, you can actually hear your engine gaining speed. as if the sound is going according to the RPM. i've only heard it about 4 or 5 times... but idk it was weird cuz it was when i plugged my ipod car charger inside and it started doing that.

 

ya..i hear it once in a while like 1 once every two days or two days in a row just whenever it feels like doing it..any ideas
and its on the outside you can hear the whislting noise..thanks

 

Maybe your v-tec kicking in?


Im pretty sure the r18's have v-tak just not as prominent in the si's

 

Ya, what i'm talking about is just the sound of the engine, its nothing to worry about. The engine just makes a high pitched whirring noise. It could be v-tech cause in the r18 it kicks in about 3300 or 3500 rpm or somewhere around there.
