2003 RSX Manual: Slave cylander has been replaced twice. Still leaking fluid until transmission freezes. Mechanic can't find source of leak. Any ideas?

Most cars also have a hydraulic clutch with 'master-slave system' that could be leaking. Also transmission fluid.
Hope this helps.

I would check for fluid at the bottom of the bell housing. The slave cylinder is inside the housing and known for leakage problems. The transmission would have to be removed to replace it.

By what you are decribing you have a hydraulic clutch check for leaks from your master cylinder (one for your Clutch) and check for leaks at the Slave cylinder (in the bell Hopusing or on the side of the transmission). likley one or the other or the line that connects your master cylinder to your slave cylider may be leaking. Also check the fluid level normaly take Brake fluid DOT 3

This may be a clutch problem or a cluthch slave, what is happening is the transmission is not completely stopped spinning, so as you try to go into gear the clutch is not disengaged completely. this can be due to a bad slave or master.

The fluid for the clutch master, make sure its full. if low then you may have a leak. if low fill and pump pedal a few times to see if that helps.

If clutch master is low or full go to trany and locate the cltuch release fork on the transmission at the end you will see clutch slave, make sure there are no leaks. have someone push clutch pedal as you watch the fork move. make sure it move the distance. if its leaking then its bad.


The last thing would be the clutch pressure plate or disc, this is hard to see without removing transmission, If something broke away from cluch plate and is jammed against plate this will keep traany spinnig, but it would also be hard to get into first.

If you can start car in neutral and put into 1st gear without a problem then thats confusing, but if it is hard to go into first also then its in the clutch system. i am guessing you are in first with clutch down when starting and then its hard to get into other gears. good day.

Brake Fluid.
It would be empty because there is a leak in the system - could be the master or the slave - there are seals in there similar to those in a wheel cylinder - using the wrong fluid swells these seals.
You may have to replace these cylinders - start with the Slave.
I don't believe that there are kits available for these but if so would be a cheaper fix.

Your transmission cooler line are leaking. Expand in the hot summer, contract in the cold winter, and leak.
Ask your mechanic about this.

do you mean a manual model ?? is the slave cylinder inside the bell housing ??if so renew it

more than likely the slave cylnder in the tranny or on the side of the tranny have you been seeing fluid on the ground.

There are two possibilities to consider:

1. the master cylinder is leaking/by-passing hydraulic fluid
2. the slave cylinder is leaking/by-passing fluid

You didn't mention a fluid leak, so that would eliminate the obvious cause of a leaking pipe. However, check for leaks around the master cylinder (on the firewall) and at the front of the engine by the clutch itself. This would indicate which of the two might be the problem, If they haven't been replaced in many years, it's probably sensible to replace both at once. The slave cylinder can be replaced without removing the engine. If you have ABS, you'll likely need to loosen/remove the alternator.

Good luck!

replace clutch disc my dear

very common in manual transmission cars
