I have a 2000 Monte Carlo SS. I just did a trans flush yesterday and the mechanic also brought to my attention that my anitfreeze is green and the car should have the Dex-Cool antifreeze. Does anyone know what this will do to my engine if I don't change it? I bought it in September from a reputable dealership with the green coolant in the car.

Sir get it changed imediately. The mechanic is right, it should have dex cool and dex cool only. the green antifreeze will ruin your engine, it will eat away at the aluminum, and will leave bits and pieces of it floating around in the engine, only waiting for a disaster. Trust me, I've seen it happen before.

The ss version has the 3800 supercharged engine in it and in 2000 probably was still made out of cast iron and it probably was changed from dex-cool because of its tendency to sludge up. If the car was running good with the green I wouldn't change it.

I have a 2000 Monte Carlo SS. At 66k the transmission went out and I put a new one in. At 84k the transmission went out again. What is up with these transmissions in these cars? I love my car, but come on!!!

I have a 2001. I bought it @ 65k miles.

It hates the rain!!! It hydroplanes so bad I bought Goodyear Assurance tires and it helps, but still hydroplanes... anyone else have this problem and or a fix???

Also thanks all for prior posts, or I would never have known about the dex cool issues and the gasket issues - Thx.

I own a 2001 Monte Carlo SS and I've been having a problem with my tranny for almost a year. It seems to take time for it to warm up to shift, and when it does it drives OK. But when you're driving in the city or highway, it seems to spike when you take your foot of the gas slightly and then apply a little gas the tachometer surges then it's fine. It seems like it has extra gears or something.

Was wondering if anybody has that problem or if someone knows what I should do? I bought it brand new, it has 118,000 miles on it, and still runs good. I've spent about $2500 on routine things. Just need some help if anyone can???

Well thank all of you, this helped a lot. I was very interested in a 00 Monte Carlo SS, but now I've learned about all these tranny problems I will stay away from one.

THANX A LOT!

My Monte Carlo has 71k miles on the transmission and I have no issues.

I wonder how many of the previous posters changed their transmission fluid at the regular intervals? Filter and fluid must be changed by 25k to 30k miles and should be replaced every 30k miles therafter. Problems will arise if you do not do the maintenance!

I bet very few of them changed the fluid, then they flame GM!

I have owned my Monte for 7 years and have not had a major problem. I have had two minor problems one being the intermediate steering shaft, it needs to be re lubed every 20k miles because it will make a curious knocking sounds and sensations through the steering wheel. Two, my center console's rubber coating started peeling off around the cup holders and was unsightly. (This is caused by the acids in coffee and pop not being wiped off and breaking down the surface). I removed the console, sanded it, and repainted it with black vinyl dye. Better then new.

To the guy hydroplaning, try slowing down going through standing water!

2002 Monte Carlo SS.

My wife's MC also has had transmission problems. I maintained the car faithfully and it has always had the best of care. The PCS went out 300 miles past the expiration of the extended warranty, 75,300 miles. Oh, and it cost us $1800 to repair at the Chevy dealer, not the $300 suggested in the GM bulletin. The car now has 102,000 miles and is shifting hard again. So the posting that said the PCS stay fixed is not 100% correct, ours is broken again. Not sure if we are going to fix it again or trade it in.

We had numerous other problems, all repaired by the Chevy dealer. The steering shaft, the turn signal control switch, the power window switch, the catalytic converter replaced, and recently both front hubs ($1000) to pass inspection. Yeah, bearings wear-out but the hubs are integrated with the ABS system so they are unnecessarily costly.

We own 3 cars, all Chevys. 04 Silverado, 02 MC, and 99 Camaro SS. Next car will NOT be GM of any kind. We're done with GM.

My son has a 2001 Monte Carlo with 30+ k miles. When he goes to start the car he has to let it set in the on position for 5-6 seconds before turning starting. Has anyone had this problem.

I have a 2001 Monte Carlo SS.

I bought the car used from a dealer in 03 with low miles.

I am just now cresting 65k on the car. Since I purchased the car, I had the warranty replace the transmission in 04. It would surge at a light or any given time. GM replaced it and stated at the time, that they had knowledge of torque converter issues, which could and did compromise the transmission. That has a 100,000 mile warranty from GM from the time of install in 04.

Just a few miles after 60k, the car started the RPM deal; floor it, and it would go nowhere. It was the catalytic converter. They replaced it under the factory warranty also. This was also a known issue they did not send a report on.

Now my traction control system has been going haywire for three years. It is my understanding that it is the wiring, which also operates the anti-lock brake system sensors.

I have disconnected the battery a few times so the computer can reset, and it seems to help, other than paying an outrageous price to have it diagnosed. They want to replace the sensors and wiring harness. Big bucks!!$.

Good luck, and for a banging rattling noise in the steering wheel, lubricate the steering shaft with a kit from GM every 15k.

I do love this car still, but it seems they would have sent out recalls on items they had problems with!
