Hi guys,

Quick question: there is a manual transmission fluid leak... and it's noticeable next to the clutch pedal... Every 2 days or less I got to fill the reservoir while the clutch pedal feels really soft and goes all the way down... at this time, the shifting is really annoying.

Well, I know which is the part, but don't know how you name it... it's cylindrical, black and made of plastic. It has a rubber seal. Days ago, I changed only the seal with an alternative one (because couldn't find an exact match around here) but it continues leaking. A friend suggested me to change the whole piece...

Please, I need to purchase it from the US but not idea abt the name. Btw, if I only change the seal, will it work?

Thanks for your feedback!

Going to have to post a picture of it.

Clutch master cylinder, thats about the only thing that could be leaking fluid without it being inside the tranny.
