    I was refering to people that have never towed (1500) and still have had problems with their trannies going out. It's not just one isolated incident either. Far as I'm concerned the trannie is the weak link and would not buy a 1500 even if I was towing only 3k lbs. Then again I don't plan on buying another Suburban either.

    GM products seem to be good for 100k miles (if lucky) then watch out. Mine is at 136k now and am spending about 3k dollars/year to keep it running the past two. Love the engine though but really think it's time for something new.

    we have the tow packages on both our Suburbans.. tranny cooler included.. so to me that's a non-issue.. and we don't tow ...

    here's the recommended maintenance for the transmission on our Suburbans.. goes for the Tahoe also..same-same book..

    you will note that the tranny fluid and filter does NOT require it be changed at 30K miles .. at 50K ONLY if used heavily under certain conditions and for ALL to be changed at 100K miles.. so maintenance except for checking for leaks/fluid levels has nothing to do with their trannies being sub-standard.. let's keep and put the blame on the manufacturer NOT the consumer.. that is the very first mention of any tranny maintenance in their schedule..

    here's a page from the '01 Subn/Tahoe book

    if a mfgr says a truck can tow a certain poundage.. then it should.. that doesn't mean it can tow it and then break down..

    I won't even get back into the serious problem with Subn front ends with excessive inside tire wear..

    Stakeout, you are right about the manufacturer's suggested 50k/100k mile transmission service interval and this is the same for an '01 Denali, but I think we all agree that heat and fluid breakdown is the enemy of the transmission. Companies are aggressively marketing their products as low maintenance, so now we have 100k mile spark plug changes and 150k mile coolant flushes. Does that mean that a spark plug is giving you the same spark at 80k miles as one at 5k miles; I doubt it. I would also be worried about pulling a trailer up Pike's peak with 95k miles on the original factory transmission fluid even if that was the only time I ever used the vehicle to tow. In these cases, I try to use my own judgment - I would rather pay $129.00 for a transmission flush 2 times before the 100k recommended allowance before risking failure due to fluid breakdown. How many people actually check the fluid level and quality (color red or black?) periodically? I may be a little over cautious; I run K&N oil filters and synthetic oil changing at the regular intervals. In fact, I would have put in synthetic transmission fluid when I had the tranny flushed, but the dealership is not really setup to do that kind of job. I'll have it done at the next interval in an off-road specialty shop. Wasted money? Maybe, but I think of it as insurance that may prevent me from having to do a major overhaul since I plan on keeping this baby a long time and I do like to put my foot in the throttle ;)

    "the two best cars that my wife.. and for that matter that I've.. ever owned for quality build were back to back new '92 and '95 Infiniti Q45's.. she never had one single problem with either car...not a hiccup.. great cars.."

    Well, for how much a Q45 goes for and the fact that it's made by a luxury nameplate (Infiniti)--one should expect very few problems with such a vehicle. What I'm getting at with this is that you are clearly comparing apples and oranges by comparing a luxury make (Infiniti)--for which a high expectation of quality/reliability would and should be expected--with a non-luxury one (Chevy/GMC).

    but it's funny you mention that.. when we leased the Q's they were at the same price level.. as today's Suburbans are in the mid 40's range.. now they are a bit more... but so are the Suburbans.. a new LT 'burban is about at $50K MSRP loaded..

    for $45K and up right now nothing should go wrong .. in theory and a make believe world... with a Suburban-Tahoe -Denali- or the Yukon twins.. the only thing different for me is that it's hard to carry a load of fishing gear in a 'Q' compared to what you can get into a 'burban.. dollars is dollars.. space is not..

    now why couldn't Ford come out with their extended Expedition this year instead of in 2006( late 2005) giving the Excursion a stay of execution until 2005 according to Motor trend.. it sure doesn't look like Toyota or Nissan will ever come out with a Suburban beater of that size..oh well.. more in the make believe world I guess..

    CR is reporting that domestic car quality has passed the German imports, but the Japanese cars are still leading. At least that's the way I heard it on the TV tonight - no link off-hand. The upshot seemed to be that GM and Ford were doing much better with car quality in recent years.

    What is an American car?

    It's not the door hinges but the check/strap.(middle hinge?)
    GM have a TBS on it and replaced it on newer model with plastic coated straps.
    I had the same problem with my 2001 and had it done under warranty, noise is gone.

    here's that article again about this year's CR quality survey on vehicles from my post in #3489

    Although post 3504 may be what your problem is, you may consider using something other than WD40. WD40 is not the best lubricant. It has some lubricating qualities but is used more for it's solvent characteristics. Try a spray synthetic lubricant or white lithium grease with the spray tube to get it into tight locations.
  • All,

    I read other posts about WD40 not being the best lubricant so I tried some spray lithium grease like you suggested. Unfortunately with no luck.

    I do think I found the TSB for this problem:

    Component Description:
    Bulletin Number: 010864015
    Bulletin Date: OCT 2001
    Vehicle: 2000 Chevrolet Suburban
    Does anyone know how I can get the details for this repair?

    Thanks for the input,
  • tdohtdoh Posts: 298
    True, but remember though--how much did a new full-size GM SUV retail for (comparing MSRP here) back in '92 and '95? Correct me if I'm wrong, but I think probably not the same price as that for a brand-new '92 or '95 Q45, respectively...

    I think one thing we can both agree on as far as current pricing for full-size GM SUVs--for as much as they go for these days, you'd think that you would get more for your money...

    I have a 2000 Suburban with 55K miles. About 1,000 miles ago I began hearing a high pitch ringing when the engine is running. I'm sure it's the fuel pump. Sound is a little less when the tank is full, and gets louder as the tank empties. Anyone else have this problem? Should I just replace the pump and anyone know how much it would cost?
  • stakeoutstakeout Posts: 173
    'ab-so-lude-lee'.. that's what I was trying to get at... outrageous prices in today's market along with their outrageous mfgr's profits on SUV's.. should equal better quality in that high-dollar SUV.. I guess they don't think like that...

    If you find out the specifics on the TSB, let us know.
  • Stever@EdmundsStever@Edmunds YooperlandPosts: 38,981
    Thanks for the refresher link, Stakeout. I guess I didn't follow your first one :-)

    The Japanese automakers best be looking over their shoulders.

    So are you just choosing to ignore the fact that all reports on reliability show that todays Suburban IS far more reliable than it was 10 years ago.
    That is the jist of the CR article, American quality has improved significantly.
    As far as tranny reliabilty goes, you state, "if a mfgr says a truck can tow a certain poundage.. then it should.. that doesn't mean it can tow it and then break down.."
    There are a couple of simple facts you are ignoring, first the tranny failures aren't occuring the first time you tow, they occur after tens of thousands miles.
    Second, as another poster pointed out, the maintenance schedule are guidelines, and they provide projections based on normal use. If you are under heavy use ie. towing you should follow a heavy use maintenance schedule and use some common sense (like checking the tranny fluid periodically for color, odor, etc. If the fluid shows signs of breakdown change it.)

    Another thing everyone wants to forget, and I pointed out in a previous post, all automakers have models that have auto trannys with early reported failures.
    I gave the example of the Honda Odyssey as one that is fairly well known, I am fairly confident in saying that the majority of Odyssey owners don't use their vans as tow vehicles.
    Ask Ford Explorer owners how they feel about their auto tranny. etc. etc.
    You don't have to tow to heat up a vehicle. If you live in the south (Ie Houston in the summer) and you get stuck in stop and go traffic your engine and tranny are going to be running very warm, do this a lot and you are going to see tranny probs.

    I am getting rough idle and/or engine quit when I turn the wheels sharply to either side. Dealer says something about computer update and cost $200. Whats going on. 2001YXL, 60,000 miles
  • All,

    I joined to get the detailed info on the "Door squeak" TSB. I forked out my $25 and went searching for the the specific data I needed.

    Well guess what I found - I found out that the TSB listed by Edmunds isn't accurate. It isn't a TSB for my C1500 LT Sub but rather for the C2500, the Avalanche and others. This ticks me off because to get another report, I have to spend another $15 for an additional vehicle.

    After this episode, I called my local chevy dealer to find out that if I take it to them, it will cost about $200 per door for them to fix it :-(

    Maybe the $15 doesn't sound so bad now.

    The NHTSA is another option - sometimes they have the full TSBs:

    been messing around with cars since a teenager... over 40 years.. know how to check for tranny fluid levels, etc.. smell 'em.. color etc.. always up to date on maintenance.. used to do my own until I got older and smarter.. those DIY days are over..

    as far as what I stated.. I don't tow.. nada.. as in zippo.. so there's no excessive load on the tranny.. we 'baby' our vehicles.. the trannies still stink in my opinion.. and they have a tow package as do most other trucks including Tahoes and Suburbans that do tow..w/ tranny cooler etc..

    so why should they have so many problems even if towing.. you sound like the Chevy/GM service managers.. " do you tow??".. is usually the first question.. why is that... I don't have a sports car .. it's a truck supposedly made for towing.. some up to 8K #'s.. or better.. if you're not supposed to tow with it and the trannies can't handle it, let the consumer know before he shells out $40K for it so he can go to the 'other guy' and buy a real truck

    and you're still missing the point..they shouldn't 'stink' on a $40K+ truck..especially with today's so called 'better-made' vehicles.. no excuse for it..none whatsoever.. they should purrrrrrrrr...

    I can tell you I know people who have had Chevy/GMC tranny troubles as far back as the old larger sized 2 dr Blazers in the early 80's.. same stuff is still going on with the 1/2 tons..

    my question to Chevy/GMC is .. why won't they put the HD type tranny in all their Suburban trucks 1500 and 2500 series not only the 2500... I guess that's in keeping with the same reason they won't put 'LT' tires on the 1500 series and use 'P' ( passenger car) tires instead.. they don't belong on a truck.. so it's a 3/4 ton or you're out of luck ... oh well
