Anyway, to get to the sender I had to pull the thermostat housing, so I installed a new 180 degree thermostat while I was in there (it was a 195 degree, and at 72K I figured it could use a new one anyway). At the 180 degree mark it seems to run cooler then the old 195 unit did, it opens right around 175 or so on the gauge (5th med size mark up from cold). I'm getting ready to do the Monte Carlo SS cluster conversion mod so it'll probably be linear also on the new gauge. First time I have ever heard of a factory temp sender going bad, I shot a pic or two of the replacement at the request of the folks at newimpala.com and I'll probably post them up later. I tell you if you ever have to replace this sender it is a bear, it's below the thermostat housing in a very awkward location to get to and it's almost impossible to get the proper pitch on it with any tool. FYI it takes a 19MM deep well socket to get the sender in & out.
Take care

I have a 2000 LS 3.8 with about 86,000 miles. I drive it 100 miles a day total to and from work. I've recently noticed a strong burnt rubber smell coming from the engine compartment. I've looked all over and don't see any wires/hoses that could be leaning against the block or exhaust.
Does anyone have any other suggestions on what I should check?
Thanks!

In this case, do the fix yourself. Pack the joint in the intermediate shaft with a good quality high temperature wheel bearing grease. Fill the entire joint, not just the .5 oz that GM sells. Use a wine cork to force the grease throught the openings, and pump the joint about 20 times before you re-connect the column. It's an hour job if you just pull the steering column and it's not worth what they want to charge you.
transmission has trouble shifting gears, engine sounds like it is racing before gear shifts.
only 59000 miles. has anyone else experienced this problem?
Do get a faint shimmy in the steering when applying brakes. Mechanic resurfaced the rotors - Heavy duty pair in front. Anyone else experience this.
can any one HELP!!! me Thanks
This was right at about 70,000 miles BTW - and I'd had the transmission serviced @ 40,000 miles or so (fluid/filter change).
Took car to dealer with 59000 miles. It was a faulty catalytic converter. It was the only item left on the warranty.
thanks for your comments.
Thanks
I left the module out of the door, so I wouldn't be tempted to accidentally roll the window down again; but doing so also makes ALL the windows inoperable. Someone had posted the option at some point of possibly switching the driver's and passenger's side switches, so I took the module apart, and while it may be possible, it looked to me as if there was some charring and melting that had gone on on the driver's side of the switch, and even if you could move a switch from the other side, I think there was enough damage to the non-changable portion of the switch that it wouldn't have been worth trying.
I checked at Auto Zone, and they can order the part for @ $92, but they were on backorder. Anybody know what the going price for this part is at a Chevy dealer? I can handle the installation, and after taking my old one apart, I'm convinced buying a used one wouldn't be worth the trouble - unless I were to buy 3-4 with what a new one would cost, and just swap them out each time one goes bad.

This bulletin is being revised to add model years and change Cause and Correction information. Please discard Corporate Bulletin Number 01-07-30-038A (Section 07 - Transmission/Transaxle).
Condition
Some customers may comment on any of the following conditions:
^ The SES lamp is illuminated.
^ No 3rd and 4th gear.
^ The transmission does not shift correctly.
^ The transmission feels like it shifts to Neutral or a loss of drive occurs.
The vehicle free wheels above 48 km/h (30 mph). High RPM needed to overcome the free wheeling.
Cause
The most likely cause is chips or debris plugging the bleed orifice of the 2-3 shift solenoid (367). This will cause the transmission to stay in 2nd gear when 3rd gear is commanded and return to 1st gear when 4th gear is commanded.
DTC P0757 may also be set if the 2-3 shift valve (368) or 2-3 shuttle valve (369) were stuck, restricted and/or hung-up in its bore.

4T65-E Transmission Delayed Shifts, Slips, Flares or Extended Shifts During Cold Operation (Replace Shift Solenoid Valve Assembly)
Models:
2001 Buick Century, LeSabre, Park Avenue, Regal
2001 Chevrolet Impala, Lumina, Monte Carlo, Venture
2001 Oldsmobile Aurora, Intrigue, Silhouette
2001 Pontiac Aztek, Bonneville, Grand Prix, Montana
with 4T65-E Automatic Transmission (RP0s MN3, MN7, M76, M15)
Condition
Some owners may comment on one or several delayed shifts, slips, flares or extended shifts during cold operation. These symptoms can affect the 1-2 shift only. The transmission won't shift out of 1st gear until the temperature is high enough to unstick the solenoid. This condition can last up to several shift patterns. These symptoms can return after the vehicle sits, usually 6 hours or more.
Cause
The 1-2, 3-4 shift solenoid valve not exhausting may be the cause of these conditions.
Correction
Replace the 1-2, 3-4 shift solenoid valve. Refer to the appropriate Service Manual information for replacement procedure.
They help make YOU visible.
Yes, they are a safety item and as such, if you are in an area of DEQ inspections, they may fail you on a safety item, such as DRLs not working.
Disabling them is not easy. You would have to rewire the entire headlight system, as they are part of the lighting system and are controlled by the body control module, which controls just about everything.
If you want to get rid of them, I would suggest you buy a different vehicle that doesn't offer them as an option. Good luck in that.
I've done alot of repairs on vehicles that folks have tried to disable the DRLs (especially GM vehicles), only to destroy something that renders the headlights totally inoperative. Usually, trying to do something like that only costs you headaches and money.
If I am driving when the car reaches the critical temp, then the 'security', 'service engine soon' and 'battery'[alternator?] lights rotate through on the dash. [it also loses the air conditioning and radio]
Yesterday I drove it 3 hours on the thruway & the ambient temp reached 76 -- no problem. Parked it in my driveway in the shade-- unloaded the car -- everything fine. Then my wife took it for a short trip- parked in the sun & it triggered the problem within an hour.
It kicks in at 79 degrees or so [according to the thermometer on the DIC], but the ambient temp has to get down to mid sixties before it goes away. [slamming the trunk seems to alter something but it isn't consistent enough to say for sure]
My mechanic changed ignition switch last week-- that wasn't the problem.
Today I'm taking it back to him & I'm going to use a hair dryer to heat up various components until we can trigger it.

Thanks,

As for the "safety" that is totally bogus based on a study from Sweden and Canada where it is dark 9 months out of the year. They are simply trying to save a buck on a wiring harness because Canada passed a law (where it is also dark 9 months out of the year) for DRL's.

Has anyone heard if they do?
When I was sitting in the garage the other day I was turning the ignition on and off without starting the engine, trying to get things to work, and everytime I turned the ignition on I could hear a faint frying sound like contacts arcing on a relay.
I don't know if it's just a coincidence, but it seems like the problem has gotten worse since our weather has turned colder, today I drove six or eight miles before I could get everything working.
Anyone else heard of or had this problem?
Has anyone else had this problem?
If you havent removed the radio for any reason, maybe you could have it replaced under warranty?
The problem I'm encountering now is that due to the odd shape, I can't just glance in the mirror to see what's going on behind me - I have to take an extra second to focus just on the dimmed area, and perhaps adjust my head somewhat to get the headlights of the car behind me in the dimmed area. I know this is causing me to spend less time looking where I'm going, and would potentially cause me problems down the road. And of course, I'm getting hit in the eyes with undimmed light, and there's no way to avoid it.
Anyone had a home remedy for this, or has anyone had theirs replaced?
anyone know how much a replacement would cost?
I own a 01 imp with the 3400 engine. Here are my problems. My air bag light is staying on all the time. I think the passlock in the ignition is going bad. Sometimes the car won't start but when we wait 10 minutes it will start up. How can I scan the car and find out what is causing the problem. The dealer ship wants $100 dollars to tell me what is wrong. Can an obd II scanner tell me anything? Does anyone know of any TSB's for this problem.
