#1218 of 2268 B-ville Transmission WHINE or HUM - ?
Dec 11, 2003 (6:54 am)
My two very recent posts describe a strange HUM or whine, to be even more exact - in my 2000 Bonneville. Firestone Service guys said "transmission." Car is on 0-deductible warranty. Pontiac service said "can't reproduce the problem." Hum remains at higher speeds at 2000rpm+ so far.
Have tried the torque converter test in message #1214 and #1216 - the spike mentioned when going a steady speed in 3rd and Drive and suddenly tapping the brake DOES NOT cause a momentary spike upward on my tachometer. Does this mean its not functioning properly?
This hum you had (or whine) message #1217: was is constant or only at a certain speed/rpm? Please advise. I am NOW planning to get my problem diagnosed by a non-Pontiac/GM repair shop, and then go back to Pontiac and say FIX IT.
#1219 of 2268 service engine soon light
Dec 11, 2003 (3:18 pm)
got in the car this afternoon (2000 SSEi) and the service engine soon light came on. Car has 55,430 on it and it just came on today. Is this something that comes on at a certain mileage or is there something actually wrong that sensors are picking up. Should I just disconnet the battery to reset the PCM?
#1220 of 2268 If it's the orange light
Dec 11, 2003 (3:27 pm)
and it's on steady, read the owner's manual--
but that's probably an emission control item
for the fuel systems. The pressure check on the
tank failed. I had one last year and it was a tube
had rotten at the end where it connects into the
charcoal canister. Then I had one last week, but it
was the gas cap was not tight. It had been several days since I had put in gas. But apparently it had vibrated loose enough that there was not seal.
Check you manual and see if the light solid means emissions. Flashing means something more important.

thanx imidazol97, the light is orange and it is on steady, not blinking or anything.
#1222 of 2268 Check Engine light
Dec 12, 2003 (3:21 am)
The powertain control module monitors various sensors on the engine, fuel, and exhaust systems. If it detects an out of range sensor signal it will turn on the Check Engine light and (usually) store a diagnostic trouble code.
Occasional flash = intermittent problem.
Steady light = hard failure.
Flashing light = more serious problem which could cause engine or component damage.
If the problem is eliminated, the Check Engine light may turn off after a given number of drive cycles but the trouble code will remain in the computer's memory. A scan tool or code reader is required to retrieve the codes. Disconnecting the battery will NOT erase the codes, but will erase any radio and seat/mirror presets.
A loose gas cap is probably the most common cause of a Check Engine light, but certainly not the only cause. Auto parts outlets such as AutoZone will retrieve stored codes at no charge in the hope of selling parts.
#1223 of 2268 Transmission whine in 1997 SSEI
Dec 12, 2003 (9:58 am)
In response to message #1218, the noise I have occurs in each gear and increases with rpm. It cycles up, then down, as each gear is engaged. It is somewhat "high-pitched", so I would not describe it as a "humming" noise. This is very disturbing to me, as I have owned a number of new and used Pontiacs - but have never had to replace a transmission. This car has been well maintained and looks nearly as good as new, despite the high mileage. Are there any other Bonneville owners reading this board with transmission noise experiences?

does anyone have a problem of an altenator belt slipping when it is wet out? everytime i hit a puddle it slips and cause the volts to drop to 12 or lower then takes a while to charge back up (about 30 seconds). Does anyone have the same problem or know how to fix it?!
Also i saw a 03 SSEi with 9,000 miles a dealer lot for $25,000, completely loaded was thinking about trading my 2000 in b/c of all the problems does that sound like a good price? I live in Mass. if that makes a difference.

Sounds like a worn belt tensioner, glazed belt, or both.

My 2000 SSEi had developed the popping or clunking noise in the steering as well (this is a low-mileage car with only about 13000 miles). This is a common problem. The dealer replaced the entire intermediate steering shaft rather than using the lube kit. The lube kit is only about $7 but one hour of labor to take the shaft out, lube it and replace it. The new shaft was $158.51 list price, plus an hour of labor.
After the repair I inspected what I could of it and noticed that the rubber boot over the shaft was pulled away from the point where the lower shaft meets the rack assembly. There is a lip on the boot and a flange on the rack that look like they should be clamped together, but it appears as if the boot just floats there. Doesn't look right but I think that's the way it was before they replaced the shaft.
Later on the day of the repair, when it was dark, I noticed that all the interior lamps were not working. Turned out to be a blown fuse, but I'm wondering what the tech did to cause that. So after replacing the fuse I decided to check everything electrical. When I went to lower the right rear window, the regulator made a cruch! noise and now the window can be raised and lowered only by hand. Another common problem on these cars. Ordered a new regulator (apparently you have to get the motor with it) at gmpartsdirect for about $90 less than the dealer wants even with shipping. Might even try to replace it myself.
#1227 of 2268 Good bye 2000 Bonneville sle
Dec 18, 2003 (10:23 pm)
I had enough. I had a 2000 Bonneville SLE that I just could not stop the tires from vibrating. I tried everything. And I mean everything. But when I finally wore out the goodyear tires and replaced them with dunlop sa sport a2 tires, which I loved and balanced perfectly, and the car still vibrated I went to my local Pontiac Dealer and traded it for a new Grand Prix GT 2004. You may ask "Why another Pontiac?". Well I loved the Bonneville. It was a good car. Even with all its problems. But the wheels just kept on vibrating. But as much as I liked the Bonne, the Grand Prix is a much better fit for me. I like the smaller size and the sportier handling. The 3800 III ,yes III , is a better fit for a lighter weight car. And the drive by wire throttle is much more responsive paired with the electronic trans. And the wheels do not vibrate, the trans shifts much smoother and at the right places everytime. I trully look forward to every drive in the Grand Prix.
Enough advertising. Just wanted to thank all you fine folks on the message board for all the info on how to repair the Bonne. It was most helpful. But it got to a point where the value of my car was decreasing and I needed to keep it or sell it. So bye, bye Bonne.
