6MT owners, change out your clutch fluid regulary.
Not sure how many of you have noticed this, but our internal clutch slave
system on the 08+ G 6MT models exposes the clutch fluid to a lot of clutch dust. The dust causes very quick fluid deterioration that has led to many master, slave units going bad. In vehicles that the dust has been allowed to build up in the lines, the fluid can be very difficult to bleed, so regular maintenance is of importance. My advice is to replace the fluid twice a year or at least once at year - regardless of fluid color/etc. Keep the fluid clean and you won't have problems bleeding the system and the master and slave will last longer. |
I drive ~6K miles a yr, so doing it 2x seems a bit excessive. Maybe once every 12-15K miles is a better interval, or just keep an eye on the color. When it starts to darken, change it.

Um, hate to ask the noob question, but does clutch fluid = transmission fluid?
|
Clutch fluid = brake fluid (dot 3/4 usually)
Manual trans fluid = gear lube (not the same as ATF) |

^^There's really not a whole lot to it. I'd probably evacuate 2/3's of the fluid in the reservoir using some sort of suction device, pour in new fluid, then it's just like bleeding brakes.
The entire system uses VERY little fluid, so flushing it is quick. The bleeder is very accessible at the MT. If you've never done it, the bigger concern would be to get the bleeder open without busting it. |

What I was wondering was if "change your clutch fluid" was the same as "change your transmission fluid," but your response answer my question anyways :)

great advice... I swapped over from the dot 3 to dot 4 and recently motul 5.1 for the brakes and the clutch and its made a world of a difference. The pedal feels smoother and the shifts feels smoother

Speaking of clutch fluid change. Need to do that some time next week. I'm almost at 60k miles.

thanks for the tip

Clutch dust getting into your clutch fluid??.....Now I've heard everything....
Not to say that servicing your clutch master cylinder isn't a good thing to do on a semi-regular basis, but thinking that your fluid is darkening due to clutch dust is ridiculous. I just had the same conversation on one of the motorcycle forums I belong to, member said that your clutch fluid gets dark because of the build-up of chain lube and dirt/gunk that collects under the front sprocket cover/slave housing. Not the case...... Funny how my V-rod with belt drive darkens up the fluid as well. LOL! I'm going to let you guys in on a secret..... it darkens due to slave and master cylinder seal wear. Every time you push down the clutch pedal the seal on the piston on both ends wipes down the LONG length of the cylinders (as opposed to the short throw of the brake master) and micro abrasions wear off the seal material (which is black) which darkens the fluid over time. Simple as that. |

This is an old thread but I just had to bump it! I recently changed my clutch fluid and it made a huge difference as far as way smoother shifts.
My old fluid was so dirty and gunky it was disgusting. I used the syringe method and did it 4 times. Now the fluid is squeaky clean. Easiest and most cost effective DIY ever! |
