Took a long ride and on the return, went to shift, and couldn't find the clutch pedal. pulled over in a sfe place and saw the pedal was all the way down on the floor. Checked the clutch fluid reservoir and it was full, and fluid was clean. Didn't see any fluid on ground, so I am thinking it is the Clutch master cylinder gone bad. Question is, how bad is it to replace? Car was flatbedded home to my garage. I have to add it is a 2006 with 7K miles. I would like to do the repair here myself. The cylinder is about $100.00 online. Any tips, hints, Help? I am in Massachusetts a bit west of Boston.

Might be worth a shot to see if your local Chevy dealer will cover it.

Thanks, but tried that yesterday and they said not still under warranty so the could not cover it. 2 different dealerships told me that!

There is a TSB #14717. You have to tell them to look it up. You will need your VIN. I don't know how many years a TSB is good for. My buddy just had is 08 covered for the same issue...as well as many others.

I would like to have a copy of the TSB and I will go to the dealer tomorrow . If anyone had one, could you email to pgf50@aol.com
Thanks

from the TSB........................


Customer requests for reimbursement of previously paid repairs to correct the condition described in this bulletin are to be submitted to the dealer by September 30, 2016, unless otherwise specified by state law. If this is not convenient for the customer, the customer may mail the completed Customer Reimbursement Request Form and all required documents to the GM Customer Assistance Center. Repairs must have occurred within the 10 years of the date the vehicle was originally placed in service, or 120,000 miles, whichever occurs first.

That is only for reimbursement for previous repairs. GM will pay for new repairs for 10 years or 120,000 miles.

After reading the TSB it appears I am out of luck since my vehicle was an OCT 2005 Delivery at the NCM

Sorry about your bad luck with GM on getting it under the TSB. I understand that there is a upgraded part that GM uses and that there are other non OEM parts that are better. You might check around a little when you do it yourself and see.

Same thing happened to me. The rubber hose to the slave cylinder burst. It's wrapped in silver heat resistant stuff by the drivers exhaust manifold.

I worry about this happening also. Lingenfelter sells a "Clutch return spring" wondering if this would solve the problem?

OP, what was the outcome with your local dealer?

Corvette_Ed

His car is outside the TSB time frame. He's going to have to foot the bill himself. I just had the same issue, but my car is still within the "10 years from the in-service date" so my dealer covered 100% of the repairs, and did a very good job at that.

TorchRedFred

Yeah me too. This and the harmonic balancer. You get the feeling that it is just a matter of time before one of the two happens, or both. When I was shopping for a 2012/13 C6 I figured Chevy must of ironed out any problems from the earlier C6's along the way. Disappointing to find out later, from research on the forum, that they never addressed any of the known issues.

So I bit the bullet and decided to replace the clutch master myself today.
Bought new cylinder online for about $90 + change. Jacked the car up, put it on stands, and took the drivers side wheel and lower wheel well housing off. Took a look at the limited space to work for removal and almost gave up. But after pondering, I disconnected the clutch rod from the pin on the pedal, pulled the clip on the quick connects between the master and the line to the slave, and wiggled and pulled and threaded the master out through the small access area. Pulled the reservoir down between the master brake reservoir and the windshield washer fill neck, and it was out. Reversed the procedure to do the install with little to no problemo, until it came time to reconnect the quick connect between the master and the slave lines. That little spring clip gave me about an hours hard time, as it is literally impossible to see that fitting with your hand in the access trying to get the spring clip in place. Dropped it a few times but only on the frame and was able to recover it. Anyways after an hour of trying, finally had it snap back in place. Connected the clutch rod to the pedal and gave it a test drive. I swear the car shifts more smoothly now, and I believe that old master must have been weak for some time.. Thanks everyone for the help, and if anyone needs to do this replacement in the future, give me a shout, I may have some tips for you to make life a bit easier!

Definitely clutch master or slave. I don't remember which went bad on my 427 but it did leave me dead in the middle of the road in the exact same scenario. Covered under warranty so I couldn't tell ya how much it ran.

Good luck with the repair!

My buddy had a Master Cylinder replacement done on his 2005 Vert, he said it felt like a new car - couldn't believe the difference!

Corvette_Ed

Mine was a drastic difference as well, and I never even realized how much. I wondered why the guy at the dealership asked me if I had an aftermarket clutch in it.

Glad to hear you got yours sorted out.

Roblutts

Mine's probably right at the cut off of the 10 year mark. Not sure if I can look up when it was placed in service? Got me wondering now what the difference feels like. I don't have any issues otherwise. Did it affect the feel of rowing through the gears?
