Mine started doing this about 3 weeks ago shifting into second. Changed the fluid and still does it. My car in an 06 with 5900 miles and it is only going into second that it does this. 1,3,4,5,6 and rev, no problem.

When was the last fluid change? What's the fluid look like?

 

[dan-t]

never by me , i've had it 20k miles.i havent had a chance to look at it yet, i'll do that today.

pump the clutch 7 or 8 times.see if it slips in gear any better,reply with answer..

 

[dan-t]

took it for ride yesterday and no grind in first, little tough in third under wot..car was not hot like sitting in traffic at track.guess heat makes it act up more..i'll just have to wait till it gets worse for the dealer to see the problem for warranty repair.bummer i'll try the 7-8 cluthch trick next time it acts up.thanks

Sounds like you need to bleed the clutch slave cylinder and replace it with Motul 600 or equivalent. If that doesn't help, you may need to replace the slave.

If you have headers without heat shields, then it's likely you boiled the clutch fluid.

Good luck,

Dan

thanks, no headers,car is all stock

 

[VicTxV10]

No headers either on mine. Would the slave only act up going into one of the gears?

sounds like synchros

If it turns out to be synchros, is this something covered under warranty?

 

[Viper Wizard]

Viper X is on the right bath. I have found many with the clutch hydraulic line to close to the exhaust [stock] system! You'll need to re-route the line to get it as far away from the exhaust as possible and put some extra insulation on the line too. That should fix it.

If you get it in gear and it doesnt wanna come out, you syncros should be ok.
