To my understanding the slave clutch cylinder works with brake fluid. I had a major problem leaking transmission fluid after my engine mounts broke due to a giant pot hole that went across the road in central america. I had the mounts replaced though I am leaking transmission fluid. A friend had mentioned that it is the throw out bearing or the slave cylinder though I heard from a mechanic the slave works with the brake fluid which is not leaking. any help would be appreciated, I miss driving my car and seems every mechanic says it is some thing else.
