allright just a basic 93 ex civic coupe... I have searched and didn't really get the answer too my ?. I know my tranny probaly has bad syncros, but when u go into gear, i hear this whining noise, like a screach... Not like horribly loud, but it's there.. Is this possibly the throwout bearing, also when i try to downshift to second gear. Going 40 mph, it just will not go, i have to rev the motor up and then it will slip in.. syncros???, i have no clue.. all these mishaps didn't really start to occur unitl after the clutch master cylinder was replaced... coincedence.... i dunno. thanks for your time and ur follow up too my ?...

 

bump for some daily help....

 

When you say it screeches when you go into gear do you mean when you take off from a stop, or when you actually put the shifter into first gear?

For the downshifting part, that kind of sounds like synchros, but why are you downshifting into second at 40? There was a thread on here where a guy fucked up his tranny case and diff because he was downshifting like it was his job.

 

this is going from a stop to go, also i was using that speed as an example, i can't even do it going 30 mph, i'm not talkin about throwin it in thier trying to act like an idiot in a stock civvy. it just feels like the clutch is trying to grab, like its jerking back and forth i dunno its wierd as hell...

 

Have you flushed out your old fluid and filled with fresh fluid?

 

yes and i even gave that syncro mesh stuff a try, since everyone swears by it, no change though

 

bump too the top, for it is lunchtime.....

 

If it's screeching from a stop I would say maybe the clutch and flywheel have glazed and is causing that. How old is the clutch? Does it slip at all?

I had that same issue with screeching noise from a start, pulled it apart, cleaned off the flywheel with some fine sandpaper, cleaned the clutch disc and flywheel with brake parts cleaner, and no more sound now.

For the downshifting, I would say synchros.

 

yeah i was kinda thinkin clutch, the car has 170000 miles, clutch changed unknown, i'm gonna guess it was cause it doesn't slip.but i'm going to do a good ol tear on it. and just redo everything. and just baby the syncros.. thanks for the help.
