Ok so I've recently purchased a 2001 1.8I vtech s and seem to have a whiny gearbox more so in reverse.
Would a change of fluid cure it and if so how much and what grade?
I don't think that's related to gearbox because it's in neutral and varies with engine rpm, I don't know the layout in that engine bay but looks like it could be a pulley, someone who knows the 6th gen Accords should be able to help.
I have been thinking the same as I watched a YouTube video of a merc and the noise was identical. It doesn't change when I turn the wheel. Is there anyway to check it's the alternator like maybe unplug it for a second while the engine is running?
