Transmission Issue After Track Day

SPOHN · 12-05-2011, 01:55 PM

Finally after a long stressful week I've got around to going over my car. First thing my dad and I did today was bleed my clutch. Soon as we started there was a good bit of air in there. Pretty shocked actually. I've bleed this several times before with no issues like this. Must have to be from the track day beating with a combination of moisture in the fluid.

Also I thought I had great pedal feel and I did but not like it was after bleeding the system. But all and all everything seems back to the norm. Shifting perfect and the notchness is gone. Maybe this will save me some dough for a little bit longer. I'd still like to hear some more input if you guys have any.

Also after looking at my brake pads I wore them babies half way out. Woot. Better get some more. I should get another good day out of them. Course there's not another track event till spring and I drive on the XP 8's. But not DD.

A lot of 'vette owners have this issue. It's caused by clutch-dust getting into the fluid. If the 370Z has a dedicated clutch-fluid resivoir/system, then I bet this could be a lot of issue people have with synchro's going out. It's not necessarily the synchro's, but rather the fluid getting very dirty and eating the seals in the hydraulics up and causing issues shifting that would feel like synchro's going out.

My solution is to suck the fluid out of the resivoir with a 60cc syringe and replace it every time I get gas. Fluid stays clean, hydraulics fresh, shifting smooth.

So many people spending a LOT of money they don't have to on new hydraulics, etc. because they don't do this in the GM world. I am thinking maybe the 370Z is similar, as the mechanics of a hydraulic clutch are somewhat universal. Could be wrong, but it's something to look into. IT got so bad that one guy sent of his clutch-fluid to be analyzed, and yes,there was a lot of clutch dust in it.

Just a thought.
