Possible Transmission issues

[Camaroshark]

Well, wouldn't you know it. I was driving today and I felt something very odd.

I shifted into 2nd gear and as soon as I hit 2000 rpm, it felt like everything just slipped... then suddenly re-engaged again at 2500 or close to 3,000 rpm.

It did it again a short while later after starting again from a light.

I was down in Miami today... drove home, still with this nagging in my mind. About 3 or 4 miles from home I decided to accelerate a little bit harder again and see if it did it... this time it did it in 1st, 2nd and 3rd....

Then my check engine light came on.

It's a feeling as though you're doing a burn out but your tires aren't spinning and then suddenly it re-engages and the car lunges forward. (and no, I wasn't doing a burn out... just normal taking off from a light... maybe a little more peppy but not slamming on it)

Thoughts guys? Am I on track to think it's the transmission? Or could it be the clutch?

I had extended warranty to 48,000 miles and I just hit 48,560 today. I know powertrain is to 100K miles but I was curious if anyone else knows that feeling / had experience with this issue.

Thanks.

Appreciate it. It's currently at The Chevy dealer in coconut creek. They wanted me to leave it overnight so they could start first thing on it.

I'll drop you a note on the matter as I know more and on resolution.

Wanted to post a follow up for those of you that might be interested in a problem that could develop with your Camaro.

Seems as though it's been touched on very few times in the forums based on my searches, so I thought I'd post.

So Chevrolet seems to have combined the clutch fluid reservoir and the brake fluid reservoir in the manual transmission Camaro.

This can cause polluting of the brake fluid, leading to possible loss of hydraulic pressure and even braking ability in the car. The oil can become super heated and you can "cook" the oil over time, again leading to hydraulic pressure issues, and eventually slave cylinder failure.

I had taken the car to the dealer initially, but they said they couldn't duplicate the clutch problem I was having as it was intermittent and it only popped up after a long day of driving. (when the oil got hot).

I took the car to Lashway Motorsports and they separated the clutch reservoir from the brake reservoir and flushed the system. Brakes and clutch feel a lot better this morning.

No one believes my clutch is toast at this point as my car's power system is still stock. (not for long though).

Hopefully this solves the problem of slippage when driving for long periods of time. Awesome stuff.

I took my car into the dealership, and they said the same thing. What I don't understand is if they know it's an inherent engineered problem and many owners are having the same issue, why don't they just separate the system? I almost got into an accident because I couldn't engage second gear while trying to merge onto traffic.

Thanks for the update! I do apologize that you experienced this with your vehicle. I hope everything runs smoothly for you now. Please let us know if you ever need assistance in the future.

And literally, it's less than $20 in parts to do this and just a little bit of work. The real work is in flushing the system and plopping in the new brake fluid.

So if you're losing a little braking ability, they are feeling a little spongy, or the clutch is feeling a little spongy and / or you are having clutch slipping after a long day of driving or long distance driving, flush the brake fluid and replace and then go ahead and do the extra clutch fluid tank mod.

It's in the forums here under the DIY but it's best to google adding clutch fluid reservoir into 5th generation Camaro.

Then if the clutch fluid gets dirty, you won't pollute the brake lines.

If you have not done the modification, get your brake fluid flushed frequently. I'd suggest annually for high mileage drivers. As built, the brake lines are NOT a closed system in these vehicles like you would expect.

You can force the clutch on these cars even if the slave cylinder is blown so if there's fluid in your driveway from the brakes or clutch, have this done!!!!!! you could, unknowingly, drain your brake fluid entirely because of this and then you're up the creek without brakes....

Thanks a lot.

Still chasing this issue. Car threw code 2635 today. Had it at another Chevy dealer and we have, isolated the issue... We think.

They say it's not a Warranty item in powertrain... Fuel system control module.

Anyone verify?

My fear is we chase problems and I'm the monetary funding of "hunting" for the issue.
Not a big deal under warranty but when it's your dime... You tend to worry....

[Camaroshark]

Well I think that solved the problem. It was the fuel system control module. I'm surprised that's not covered under power train warranty.

At least the dealer said it wasn't.

It's finally repaired. The car threw the same code again over the weekend so we're pretty sure that module was the culprit.

Had an 02 Z06 with the seperate clutch reservoir still cooks the fluid. Lots of heat stress in that location. I learned from another, fourm to use a turkey baster to remove as much fluid as possable and replace with new. Never a problem from that point on. Have enjoyed more than my far share of 6M GM products.
