Last week I stared having problems with the car because whenever I shifted it did like a grinding kind of noise on all the gears . I change the trans oil but the problem didn't go away. About 3 days ago I felt the clutch pedal lost pressure and the car wouldn't shift to 1 or reverse . After this happen I went and flush the clutch oil and fill it out again but the clutch pedal has no pressure and dosent come back up. What could it be the master cylinder ? Slave cylinder? Clutch?

 

sounds like either the master or slave cylinder is bad. but when my slave went out on me i didnt have any grinding when shifting gears.

 

It only grinded the first times I shifted if the cars was cold . After the car gets hot it shifted normal . I don't I have problems with all my syncros but I could be wrong.

 

def sounds like slave/master cylinder problems..... check in the footwell around the clutch pedal and see if there is any fluid where the rod goes in the master cylinder, there should be a little rubber grommet that you have to pull back first

if it was the clutch itself, it would most likely get worse with heat... so you can probably rule that out

 

yes I check on the rod were the rubber part is and there is a black fluid coming out of the rubber part. Well ima take take both the slave and master today to check anyways.

 

Yeah, thats just either one or both of your cylinder's leaking. Swap both out. Shouldn't cost more than 300-400 at a shop usually.

The master is 120 new, and slave is usually under 100 bucks. Installation and bleeding.
Ask for your old cylinders back though. Chances are one of them might still be good. Usually all it is to fix is replacing the seals.

One thing before you replace the cylinders is to check under your Clutch fluid resivoir. Sometimes the flex line under the resivoir leaks. Feel around your clutch fluid resivoir for wet spots and look right under it for wet spots aswell.

 

Dammit I didn't know the cylinders were that expensive . Oh well might as well change both of them out while I'm at it.

 

Thats brand new and genuine honda. I wouldn't really reccomend going with any other brand.
