Oldsmobile Aurora



  • garnesgarnes Posts: 950
    Blk97 - I just have two in the back - one on each side. I really looked good and saw no fittings up front. I got an old 77 monte carlo sitting in the garage. I think it has a total of 11 fittings (something like that). I'll look at that so as to maybe clue me in on something. I'll call an Olds dealer Monday too. You got me wondering now, but I swear I saw nothing at all.

    I know what you mean about the $$. I'm in a fortunate position right now, but that price (all these systems are big money) get's me questioning myself. I'll definitely want my old one back - shipped if necessary. At the very least, I'll keep the exhaust system, my better air box, and the MAF and sell it someday or put it on the next Aurora. Hey, this system (all cat-backs except for the RSM system) does not replace the converter. It won't change emissions at all. I'm sure it is legal everywhere.

    Interesting thought (for me anyway) on that growl you get on hard accelerations with the box modified. I like it, but of course you could not sell a luxury car to the general public like that. I noticed my wifes Impala 3.8 air box has no double wall or liner at all - but it is quiet. My theory is that the Aurora air box has a rather large open volume inside. It resonates like a drum - hence the top liner and the goofy plastic bottom insert and the air horn. The Impala air box is really up tight and close to the filter on both sides. I believe this is to eliminate any resonations and results in the most pee-poor air flow characteristics you could imagine. You know, I wish they would just design the air intake right on the inside and then double wall insulate it from the outside if needed to reduce noise. They do just the opposite and give away performance. After designing something as nice as the northstar engine, why to they do stupid stuff like this?

    You know Blk97 may have a point. I am in New Jersey also (Newark), I wonder if the state will havve a problem with this mod? However, I too think that it should not make the car run dirtier. Is this correct?

    As crazy as this sounds. I really need to check back with the dealership. If the major cost in the exhaust is the cat, I need to assess exactly how much this little X-mas gift to myself will cost.

    Is it REALLY BEST to go with the factory cat???

    The car just turned off the traction by itself. I went from a stop and spun the wheels (not on purpose) to get through an intersection. I noticed that after I went through it the traction off light was on. I tried to use the button to turn it back on but the button did nothing. I had to turn the car off and start it again.

    Has this ever happend to anybody???
  • Henry-
    i have also had some slight problems with my traction control in the past. my Aurora is also a 95. The problem i had is that even sitting still in park with the engine running, the traction control module would fire up and i would hear it pulsating the front brakes. it would turn the "traction off" indicator light on after about 3 seconds.
    what it turned out to be, is that my front wheel bearing had to be replaced. there is a wheel speed sensor on all 4 corners of the car, and they can get false signals with 80,000 miles (in my case) worth of dust and dirt in them. i changed the left side myself, it was an easy job which fixed the problem for about 3 months, it's just starting to do it again, so i guess i'll have to do the right side wheel bearing now.
    i hope this helps.
  • I've been thinking about getting an '02 Aurora, but my main concern is quality after having driven a Trans Am for several years. For those of you with '01 Auroras, what has your experience been? I had been leaning towards getting an Acura TL-S in recent months, but GM's low prices, 0% financing, and my GM Card earnings are not easy to pass up.

    Perhaps I will reconsider using all Mobil 1. It's just that it is so expensive...

    blk97aurora: Where do you go to get the AC Delco UPF-58? All I can find is the regular Duraguard PF-58. I have checked Trak Autos and Pep Boys as well as Wal-Mart/Target type places. I always have a hard time finding AC Delco products (especially Dexron-III) at local stores. Sometimes I'll find local Mom & Pop auto parts stores that might have what I'm looking for, but it will be covered with dust and the packaging will be two styles old, making me hesitant to buy it.

    I have noticed the maintenance schedule on the Olds website mentions greasing the chasis, but the owners manual's maintenance schedule makes no mention of it. I haven't accumulated enough miles yet to worry about it. I will check and see what is there around 7500 when I pull the tires to rotate them. If there aren't any fittings on your car, it is possible that the fittings just weren't put in but that there are threaded holes for them. It's also possible that the car uses permanently lubed bushings and therefore doesn't need to be greased.

    On another note, I just took my car to the dealer today for an annual VA state inspection. Does anyone else live in VA? I really hate the annual inspection requirement. My door handle and steering wheel got all crudded up. This always annoys me. Plus, now there is some damn sticker in the windshield and I wonder how it will affect the light sensor for the headlights (I bought the car from a dealer in Maryland so it didn't have the VA sticker in it yet). Fortunately they didn't try to wash the exterior or anything. I hate that too because I don't care if the car gets clean if it also gets covered with swirl marks. I really hate taking my car to service places... Nobody cares about your car as much as you do...
  • The GM transmission designations go like this:
    first digit(4) means number of speeds
    second digit (t) stands for transverse
    third and fourth digit stands for the distance between gear centers (in this case 80mm)--generally the larger this number, the greater the torque capacity since it indicates the size of the gears.
    the last digit (e) does stand for electronic which they all are and have been for several years.

    Some of you (shucknet & others) do not seem aware the General Motors has a web site! Anyway the 4T80 is rated for 460 ft-lbs (305 engine). Don't ask me the difference between transmission and engine ratings but I suspect that the engine rating is the max for an engine.

    My 98 does not use any oil to speak of between changes since the oil leak was fixed (valve cover). I would guess that if you use the oil monitor & conventional oil you will have a long engine life. I take my car to dealer ($25) for grease and oil change (about twice a year).
  • garnesgarnes Posts: 950
    blk97 - I called the dealer, they said that even cars from the same year could have fittings up front or be sealed. It just depends. They suggested that I stop in to confirm this, but I'm pretty sure I do not have any fittings up front.

    Henry - I do not see how at cat-back exhaust system would affect emissions. It doesn't touch the converter. It's all about flow. Anyway, I just got off the phone with Corsa. They said that they may be able to do one more while I'm up there. After I'm gone, they may not be able to do another because they will not digitize the system and make molds. I'LL BE THERE THIS FRIDAY the 30th. So, if you want this, you have to call Jim Browning Jr. and give him an order with your credit card before Friday.

    Note - they said that the 2001 and 2002 system they did was very similar to the Seville, so they could probably do these more easily if anybody wanted one. Just call. They said it really made the Aurora jump. After doing mine, if it doesn't require too much custom work, there is some chance that systems for the classic can be made from the existing Caddy system they have - but this is a big IF at this point.

    My 95 is doing the traction thing on and off right now. How do I change the bearings and can I get them at Autozone? The sound seems like it is coming from the drivers side. I tried the car wash with the high pressure hose around the wheel sensor and it seemed to work for a little while.

  • HenryHenry Posts: 1,106
    Let me know how it turns out. I do not want to change my system until after the winter. Why put in a new system and then subject it to a New Jersey winter with all the salted roads to go with it??

    Maybe they will be able to do me later in the Spring.
  • garnesgarnes Posts: 950
    Well They told me that after I'm gone, they will not likely be able to do another. It may be now or never unless they discover that the Caddy system is actually easy to convert. I asked the same and they said they get pretty busy in the spring with the regular production stuff. The system is 304 stainless steel too. It's not the same stainless as the stock system. 304 is great stuff. We specify it all the time at work for sewage pumping stations where there all sorts of corrosive gases like hydrogen sulfide that could attack it. I think the 304 pretty much will never care what the road throws at it. It should always look nice. The tips are 316 which is even better.
  • gisom-
    the wheel bearing is very easy to change, providing you have the right tools. i did the entire job in about an hour and a half. i am always working on someone's car on the side, so i've got quite a warehouse of automotive and shop tools. you need a very large socket(i can't remember the size off the top of my head) to remove the nut on the end of the CV shaft. that should be the only specialty tool you'll need.

    as far as using a pressure washer to cure the problem,it's a very bad idea. i made the same mistake but only i used a mild degreaser and just garden hose pressure. after a short time, the bearing made alot of grinding noise from being doused with the water because the ball bearings had actually started to rust. you have to be very careful not to get water on the bearings and speed sensors!
    i think Autozone does carry the bearing,i picked mine up at NAPA for 160$ with a lifetime warranty.
    let me know what you decide to do.
    good luck.
  • rjs200240:

    I bought all mine at 2 or 3 Pep Boys stores in central NJ. As I recall, regular price was $9 or $10; I think I bought 2 on sale for $8 each.

    If you cannot find them, let me know what you need and I can buy one or more and ship them to you.

    Anyone here replaced the shocks and springs on a classic? I'd really like to make mine handle a little better. KYB makes a set of shocks for the fronts (it looks like you can't replace the rears?) and Eibach makes a set of springs that lower the car about an inch.

    It gets my goat that a friends 15 year old BMW 6 series with 180K miles on it out-handles my car.

    Comments or experiences, anyone?

    If you saw a 2002 Aurora 4.0 with the license plate "49OF51" would you know what it means? The only problem is on VA's heritage plate (the only nice looking one, it has the state bird on it) you can only put 6 characters and one space. Therefore it is bunched up a bit and the "o" in "OF" looks like a zero. I could put "49 OF51" but that looks worse. They have an autumn plate with some leaves on it which allows two spaces, but it doesn't look as nice.

    If you want to give me advice as to which plate looks best, go to:
    Keep in mind the car is "cherry" which is a darkish red color. The two plates I'm considering are "Other:Heritage - State Bird" and "Other:Scenic Autumn" The regular VA plate (cheaper) is "Other:Blue and White(standard)" but I think it looks like crap. It is too plain.

    As long as it isn't too cryptic and Olds fans can figure it out, then I will probably get it. (If you live in VA, don't steal it from me!)

    (If you don't know what it is, it refers to Oldsmobile's domination of the Indy Racing League with their Aurora engine. The Aurora engine won 49 of 51 races since it started in January 1997 until it's last race in October of this year.)

    My 95 failed the emissions test. The CO (air/fuel) s/b 15 and read 22.5. The HC (unburn fuel) s/b .80 but read 1.13. Is this my O2 sensor and EGR VALVE?

  • garnesgarnes Posts: 950
    Since you have the 95, I think you are OK to just order a high flow converter from Flowmaster. It might even add a HP or 2. You seemed to be looking for a replacement converter. They have one for a 95 car.
  • fjk57702fjk57702 Posts: 539
    Could be O2 sensor, the computer should say. Also could be a bad converter.

    rjs: Since I don't follow racing, the 49of51 didn't mean much to me. But I did sort of figure out the it must mean 49 out of 51.
  • When my 6-year-old battery died earlier this month, I had the impetus to find a source for ACDelco parts at prices lower than GM dealers charge. I found one not too far from where I live and work (central NJ). It's Neptune Auto Supply in Neptune City, NJ. They carry GM, ACDelco, Delco Electronics, plus much more. Their discount ranges from 10% to 40% depending on the product. The web site is They ship anywhere. No sales tax charged outside of NJ.

    I have no financial interest in this supplier. They saved me $$$ on my battery purchase plus hardware to install my newly acquired cd changer. Pat cleared my posting this information. I cannot give the phone number, but going through the web site is probably better anyway.

    RJ, IMHO your posting makes the You Know you Are obsessed with your Car List:

    -- You know you are obsessed with your car when you color coordinate your license plate with your car and put a subliminal message about the car in the license plate itself.

    Personally RJ, I am PROUD of you.
  • HenryHenry Posts: 1,106
    I spoke with my mechanic today about your Corsa modification. I asked him if it were possible for me to order an exhaust system for my 95 based on the custom work they were going to do on your car. He informed me that it would not be possible for me to order an exhaust system for my car based on modifications done on your car if your car is not a 1995.

    1995 was the last year before GM went to OBD2 with increased oxygen senors and someother modifications. While it is possible that the connection to the mufflers would be the same, the connection to the CAT would not be the same for all years. I believe you said your car was a 1998. Therefore, only other folks with a 1998 could order a system from Corsa based on the work done on your car.

    This is also the reason why you said that I could get a Cat from Flowmaster for the 1995 that is not available for other years.


    P.S. I dropped off my car at the shop today for
    repairs to the alternator and the power steering unit and whatever is causing the tranny problem that triggers the "Check engine light".

    Jerry did tell me that certain transmission error codes will turn off the traction control system on the car.

    There was a question a few postings back about the suspension. I believe tht 1997 has its own unique suspension for somethings. 1995 and 1996 are the same, as are 1998 and 1999. I hope this helps.
  • I was looking at erebuni website today and I noticed the aurora w/ ground effects looks different. It could just be me but did they change it? I didnt like they way they looked but for some reason now I do. Anyways, how much do you think it would cost to get these painted and installed? A rough estimate will do.
  • I should of posted this in the club forum but I didnt find a spot that it fitted in and I think more people read this board.

    Erebuni offers a club discount of 20%. If you were to buy the ground effects that would knock $157 off the total price of $786. (Assuming I did my math right and also assuming that the webprice they advertise now will not be discounted(they offer discounts off of web prices on certain items))

    Now in order to recieve these discounts a letter from the club president with the club letterhead must be sent to Erebuni slong with a list of all the members of the club and their info along with some info about the car club.

    Now my question is, does the Oldsmobile Aurora Owners Club here at edmunds classify as a club? If so who would be the one to send this letter? $629 isn't bad for a whole ground effect kit. What do you guys think?
  • Henry--My '95 had the check engine light come on and the code was the input speed control in the tranny!!!!!! They had to go into the tranny to replace it. It cost $1186.30 to fix it. Lucky I had the extended warranty. The part cost $26.61. It took them about 12 hours worth of labor to pull the trans. and replace the part. I can't see any difference on how it runs, but the check engine light doesn't come on. Hope this info. does some good. The mechanical work was done at the Olds dealer. I asked the mechanic that worked on it what it would cost to go ahead and overhaul the trans. He said approx. another $3000. Has anyone tried putting a "shift kit" in their trans.? I guess that is what they still call the kit when they take out the sliding easy shift these trans. have. I know the trans. will last longer when it shifts direct and fast. Any suggestions?
  • Do I really smell that bad?

    Might be taking my Aurora down to Carlisle Compact Power Jam w/ the A.S.O.G. club. Looks like a helluva car show and lots of stuff going on. It's is May 3rd-5th. Anyone else going? I ASOG member is going to unviel his 400+hp Avenger. Can't wait. This will be the first trip longer than 4 hours I've ever put on my car. Any words of wisdom for the long haul?
  • rjs200240rjs200240 Posts: 1,277
    I know that the Aurora 4.0 engine was significantly changed from the 99 to 2001 model year. At the same time the Northstar was significantly changed too. The Northstar retains the same power ratings as before (as does the Aurora), but now can run on regular gas.

    My question: Was this changed on the 4.0 also? My owners manual states that the use of regular fuel is fine. Was this the case on the first (95-99) Aurora V8?

    Matrixfrog: At the minimal, make sure the fluids are all topped off, that the oil won't need to be changed before the end of the trip, and that the tires have the appropriate amount of air in them (and are in decent shape.) What is ASOG?
  • fjk57702fjk57702 Posts: 539
    The first generation Aurora recommends premium gas. The torque and horsepower numbers are the same but there are differences. On the premium fuel engine, the torque is 90% or more over the RPM range 1700 - 5600. On the reengineered aurora the range is 2300 - 5600. Below 2300 you have less than 90% of the peak torque. Car & Driver made this known or perhaps Motor Trend.
