I am having a weird issue. I have a Honda Civic 2008 with a Prosmatec Transmission. My carās mileage is 74K kms. I changed the fluid at 68K kms with Honda DW-1.
Yes, I did NOT flush the transmission. I just replaced the oil that came out of the drain bolt. Thatās pretty much it. And neither did I change the transmission filter.
The problem is I have started to hear a whining sound from the gearbox, in 1st and 2nd gears. Usually when I launch the vehicle, itās heard the loudest. Itās just a whining noise as if it had a SC installed Lol. Like a turbine.
Itās definitely the gearbox, thatās for sure. Releasing accelerator quiets it down a bit. Going into neutral really solves the problem apparently.
The whining can also be heard in higher gears e.g while cruising (highest ratio, low load) with windows up, no music and no fan blower but you really have to put an ear to it to notice it and that I guess is pretty normal.
I think the 1st and 2nd gears are worn out? That causes this whining and person sitting in the passenger side wonāt notice it, or anyone else in the car unless you ask them to notice it and once they do, anyone can sense itās there.
So I have a few questions that Iād be really thankful if you could help me out with :
- Is transmission replacement or overhaul the only option to fix it?
- Will changing the fluid again (prematurely in my case) help it?
- Itās a Prosmatec so it requires DW-1. I think Z-1 has more friction, if my gears are worn out will using a fluid that provides a bit more friction quiet it down a bit?
- How could a 74K km driven vehicle develop this? (I bought it new 12 years ago).
P.S ATF fluid level is good, transmission shifts so peacefully, no slips, whether you have a light foot or a heavy one.
Engine itself runs with 5w-30 perfectly. The services it has got till this date are fluid changes, plugs and throttle service for the first time at 60K and one engine mount replaced. Thatās all of it. All wheel bearings are good too. Power pump has started to whine a bit too but I know how to differentiate whines between the two.
Thanks a lot! If anyone could suggest or help or has fixed somewhat same issues let me know!
