    Yes the 2007 LS460 gets 1 MPG better combined mileage than the 2006 LS430. However you give up 4 cubic feet of passenger room and 3 cubic feet of trunk with the new LS460. These figures are posted on the EPA fuel economy website.

    I do not know what GM has planned to compete in this class. I hope something. I think the 8 speed transmission was built for one ups-man-ship.

    Now they are saying "everyone" is moving beyond 6 speeds which is a lie.

    Please provide a link that stated "everyone" is moving beyond 6-speed.

    If you can't then let's just drop it before it gets too ugly.

    "Also, as torque_r mentioned, the Lexus 8-speed is lighter and more compact than its 6-speed. Which, by the way in case you couldn't put 2 and 2 together, is very beneficial in terms of reducing the overall weight. "

    I dont have a problem with the 8 speed and I can easily put two and two together. Seeing as though the LS starts at $60k the fact that it has an 8 speed means little to me. for cheaper cars the 8 speed is not a reality and it wouldnt even make sense for Lexus to try and force customers to pay for an 8 speed in cheaper cars because the benefits over a 6 speed are minimal.

    Mileage can depend on a number of factors and the LS' 8 speed is ONE factor that lead it to post better mileage than some of its competitors. I sincerely doubt that people paying $70k for a car care about 1mpg. I doubt anyone purchasing the LS is doing so solely because it has an 8 speed vs the 7 speed in the S550. As usual, the LS big price advantage is its biggest plus.

    Read the IL news brief for yourself, it clearly leaves the impression that GM is playing catch up to its peers by focusing on "outdated" 6 speeds. SPecifically it says: "While GM focuses on six-speed gearboxes for the foreseeable future, the rest of the world is moving to seven- and eight-speed units."

    What did you get from it? I think its pretty self explanatory and totally inaccurate. Accuracy doesnt count when you are cracking on GM though. Unless you are on the Edmunds payroll I dont see why you are are so adamant that they are 100% objective. There is no excuse for what they wrote and this type of attitude is just one more reason why people perceive GM (and all domestic brands) as inferior to Asian brands.

    I thought Corvettes had 6-speed transmissions for years?

    Agree.

    However, you couldn't deny that the new "world's first 8-speed" claim did give Lexus the ability to market the s**t out of it. Good publicity stunt too. I know you wouldn't fall for it but there are many others who would.

    Which sounds more impressive to you (okay, not to you, to the majority of the population):

    World's first 8-speed automatic transmission

    vs

    World's first advanced 6-speed automatic transmission

    In this business it's all about having decent products (which GM is doing right now) with good packaging (which GM sucks at it) and market the heck out of it (which GM also sucks at it except the it's ourrrrrrr country ads).
  • louisweilouiswei Member Posts: 3,715
    All right, I gotta agree with you that saying "the rest of the world is moving to seven- and eight-speed units" is totally inaccurate and it appears that they are trying to bash GM just for the sake of bashing GM.
  • gagricegagrice Member Posts: 31,450

    I put the 8 speed trans in the same category as the hybrid. Too much complexity leads to more problems in the future. I am not talking about the fat cats that lease and dump after 3 years. For those of us that buy a car for the life of it. Hopefully 15 or more years.

    I would be more apt to buy a vehicle with a tried 6 speed transmission than first one out with a 7-8 speed.
  • steverstever Guest Posts: 52,454
    If eight are good, an infinite number of tranny speeds must be heaven. But there doesn't seem to be too much excitement about CVTs.
  • lemkolemko Member Posts: 15,261
    I wonder if those 6+ speed transmissions will last as long as the "antiquated" 4-speed in my 1988 Buick Park Ave? I can imagine how fierociously expensive a failed 8-speed transmission will be in an out-of-warranty 10 year-old Lexus LS460. The tranny tech will be calling his wife, "Guess what, honey? We're sending our kids to Harvard!"
  • bumpybumpy Member Posts: 4,425
    Yet, GM gets slammed for their use of 4 speeds, which ALWAYS perform flawlessly.

    Always? Not in my experience. I consider "chunk"ing and surging to be flaws, though GM is hardly alone in foisting that upon the general public.

    I'm not sure what you mean by saying GM sucks at "packaging". If you are talking about wrapping your product in attractive sheetmetal than I would say GM is doing pretty well there lately. I think GM design is way ahead of Ford, Chrysler, Hyundai, Nissan and Honda. If you are talking about packaging in terms of options, I think GM does OK there as well. Toyota and Honda are the ones who tell you the best way to have your own car equipped. GM usually lets you get a vehicle any way you want it.

    Cerberus will have something Daimler didn't have – the implicit threat of holding back funding and putting Chrysler into bankruptcy if the UAW doesn't cough up. In the weird world of the UAW, having a profitable parent is a business liability that the deal overcomes.

    Private equity's arrival in the mainstream auto industry has been heralded with much gnashing of teeth about short-termism. Ironically, a source of disappointment to many in the peanut gallery may be that the gains from even modest health-care discipline and productivity concessions are so potentially large that Cerberus won't push for a more thorough shake-up of Chrysler – say, walking away from the UAW and hiring replacement workers as Caterpillar did in its seismic showdown with the union

    But it's too bad Cerberus won't be the revolutionary force in the auto industry that many are hoping for. A Chrysler truly freed from the UAW would let us finally see how a homegrown automaker could do in global competition while still providing good jobs at $47 an hour (just not gilded sinecures at $95 an hour).

    what GM trannies are you talking about? The press and car enthusiasts generally acknowlegde ALL of GM's 4 speeds are pretty much flawless is shift quality. Its not even something that is debated these days. You cant be taken seriously if you are suggesting that GM trannies arent as smooth shifting as their counterparts in import cars.
  • bumpybumpy Member Posts: 4,425
    Lessee... '98 S-10, '98 Deville, the Citation (though that one was a 3-pot), etc... All of them lurched when put into gear, and all of them made a disagreeable whoosh-chunk noise when changing gears. Ford and Dodge aren't any better. My dad's Avalon whoosh-chunks slightly when changing gears, and his E320 didn't whoosh at all. My sister's '92 Corolla didn't whoosh, her '99 Cavalier whooshed a bit, and the TL didn't whoosh.

    The press and enthusiasts are full of cheese.

    ï put the 8 speed trans in the same category as the hybrid. Too much complexity leads to more problems in the future

    That depends on what type of problems you are talking. Transmissions are designed to last the entire life of a vehicle. Of course, we know many of those transmissions fail to do so.
    A multi-speed transmission, say 7- or 8-speed, is less likely to break than 3- or 4-speed, however. Why? Because the spacing between gears is so low that when a gear shifts, the power doesn't "jump" from a gear to another. Power transfer is smoother and more relaxed. Sure, there would be some hesitation problem, due to less-than-optimal programming. But generally they should be reliable and last long.
  • gagricegagrice Member Posts: 31,450
    With all the problems that Toyota is having with their Camry 6 speed I would want to wait a while and let the bugs get worked out of the 8 speed from Lexus.

    I really liked the 5 speed tiptronic in both my Passat TDI and Sprinter RV. Those were very smooth in manual or auto mode.

    The 6 speed in the Escalade I drove was seamless. Just like silk, sooooo smooooth.
  • 62vetteefp62vetteefp Member Posts: 6,043
    Just to educate myself here is what I found at Toyota for autos

    LS 8 speed $61K base price
    IS/ES/GS/SC 6 speeds
    SUV's 5 speeds
    Toyota cars 4 or 5 speed
    Trucks 4 or 5 speeds
    Scion all 4 speeds
    Hybrids CVT's

    No, GM is not behind the world leader except for one vehicle and is even or ahead in most others.

    So today GM seems to be very competitive in tranny speeds. 3 years from now? All depends on what everyone does. i surely do not know the answer to that. GM was behind in trans but jumped ahead to 6 speeds when Toyota stayed at 5. Perhaps GM is now working on 8 speeds for it's bread and butter vehicles?

    Pretty sure the "bugs" are already out of the Toyota Camry 6-speed.

    As matter of fact, the 6 speeds on the Lexus IS, ES and GS are all pretty much trouble free so far.
  • louisweilouiswei Member Posts: 3,715
    Uh... I think 62vette needs to educate himself more...

    Camry V6: 6 speed
    Tundra 5.7L V8: 6 speed
  • 62vetteefp62vetteefp Member Posts: 6,043
    I should have said that I did not look at each model and might have missed one or two. Thanks for pointing out that the newest models do have 6 speeds. Do we think the new Corrolla will be a 6 speed?

    Even so it looks like GM is even/ahead in most segments. New GM Trucks have 6 speeds as do new midsize products.
  • torque_rtorque_r Member Posts: 500
    Will the 2008 Suburban/Tahoe/Silvarado have the 6-speed? it is understandable to have it exclusive to Cadillac the first year.
  • louisweilouiswei Member Posts: 3,715
    New GM Trucks have 6 speeds as do new midsize products.

    Uh, wrong again...

    Both the 2007 Chevy Silverado and GMC Sierra only come with 4-speed.

    The 4.0L V6 and 4.7L V8 Tundra come with 5-speed while the 5.7L V8 version comes with 6-speed.

    Saturn Aura XE & Greenline: 4-speed
    Saturn Aura XR: 6-speed
    Pontiac base & GT: 4-speed
    Pontiac GTP: 6-speed

    Toyota Camry I4: 5-speed
    Toyota Camry V6: 6-speed
    Toyota Camry Hybrid: CVT

    Do we think the new Corrolla will be a 6 speed?

    Don't think the new Corolla will come with a 6-speed since it'll come with 4-cylinder only. Expect a 5-speed auto as standard.

    >Transmissions are designed to last the entire life of a vehicle

    Certainly doesn't apply to Hondas a few years ago. They extended the warranty because of failures. Camry, Avalon, ES model have had transmission problems.

    The Japanese version gets a CVT as the only automatic. The domestics had better bust a hump on their CVT programs, or they'll get left behind again.

    Edit: the Auris (Euro Corolla) also gets some sort of SMG box. No slushboxes anywhere, though.

    Actually the GM trucks do have 6 speeds just like the Toyotas. They are only on certain models at both companies. GM will have 6 speeds on all models once they rampup the plant capacity.

    The new Corolla automatic will be a 5-speed. Will the next Cobalt have a 5-speed?

    I despise automatics so I don't much care either way, but representing that the industry makes 6-speeds the norm and is already shifting to more gear ratios was wrong of that article writer.

    GM made a good decision in going straight from 4 speeds to 6 in their automatics, because they were notably behind the norm with such widespread use of a 4-speed. More gear ratios will allow them to reduce the size of their engines somewhat while improving fuel efficiency and maintaining the performance standard GM buyers are accustomed to.

    Now if only they could eradicate the last of the 4-speed autos in the large cars! And certainly, the number of gear ratios is price-sensitive, so cars in the Aveo's class (for instance) can be expected to use only four for some time to come I think. Nissan's CVT and Honda's 5-speed provide the exceptions to this rule.

    The compact standard seems to be changing to 5-speed autos for new models, let's hope they are working on a better automatic for the next Cobalt.

    The Consumer Misreports June issue has a comparison of large sedans. The Lucerne is blamed for a large turning radius. Is it larger than the DTS's turn radius? I didn't look up any revew of DTS to see if CR commented there. Why does Lucerne have a larger radius? CR acts as if that makes the car very hard to handle.

    They also are a little more toward middle-of-the-road in their choice of words about the GM product. They are just not negative in shortcomings of some of the other cars in the group, i.e., the ES 350 whic was much slower than the Lucerne in the accident avoidance. If it were to have been the other way around, I'm sure it would have been mentioned negatively in the Lucerne review. Old dogs don't change their spots.

    The Lucerne is rated for the CXL and CX as having shortcomings in their suspensions compared to the CSX which CR had reported upon. They also say only the CXS has the stabilitrack available. Is that right?

    The GMC Acadia is a 6 speed and gets pretty decent mileage. I don't think Toy/Lex has a competitor in that segment. I would like to try one out. I kind of like the looks.
  • m1miatam1miata Member Posts: 4,551
    Well my '87 Olds. transmission last 62K miles. I suppose the new 6 speed should be able to top that. :P

    I would think a 6 sp. or a 5 sp. is plenty to give one a pretty good tall gear or two, while giving a nice spread in-between. As far as durable or smooth, when compared to the old 4 sp. once the bugs were squished, and it was perfected, perhaps nothing better in that respect. The old Cadillac Seville had a very smooth 4 speed. But, there is nothing wrong with a very smooth six, as if memory serves me right, will not cost more than a 5 sp. to build, and may enhance performance and gas mileage a bit.

    My car has a 5 speed, with a selection on the shifter for 1st, 2nd, and a 3rd which works out well for those country curvy roads where you drive under 45 MPH, or if going downhill is steep and you car to keep speed down. The drive selection takes care of 4th and 5th tall gears, and gas mileage is not bad. The new 6 sp. of GM gives even more spread, with around the same gas mileage, and with the paddle shifter you can hold the gears below say 4th or 3rd for those country road corners. Both work fine. Both seem to be better than having only 4 sp. Can I live with less? Well sure, cars had 3 sp. or even 2sp. but things change, and sometimes for the better.

    One hopes, and prays, that the new cars will not become too expensive to ever repair, and thus disposable. The seven, or eight speeds seem like overkill. Like someone else pointed out, why not go CVT at a certain point.

    The GMC Acadia/Saturn Outlook is NOT a truck, it is a station wagon/minivan with higher ground clearance.
  • nippononlynippononly Member Posts: 12,555
    Well, the Toy/Lex competitor for the Acadia is the Sienna XLE. Fuel economy and performance are a bit better in the Toyota, seats-folded cargo capacity is WAY better, and the real-world price is about $2K lower. But you do have to deal with the "minivan stigma", whatever that is! ;-)

    I dont know about the '98 S-10, but most GM 4 speeds are very smooth. GM shift quality is second to none, at least on their 4 speeds. I have ridden in several 90s era imports and rarely was the shifting as smooth as it was in a GM product.
  • 14871487 Member Posts: 2,407
    CVTs are a waste of time and for your information GM and FOrd had CVTs on the market several years ago. The Ion and Vue had CVTs about 4 years back but GM dropped them. Ford currently offers a CVT in the escape hybrid, 500 and Freestyle but the latter two will soon get 6 speeds. Check your facts. Nissasns CVT models hold little if any mileage advantage over comparable 5 and 6 speed trannies. The Altima V6 gets 22/28 with a CVT while the camry gets 22/31 with a 6 speed auto.
  • 14871487 Member Posts: 2,407
    The lambdas are a unique chassis that were purpose built, they are not station wagons. Most Japanese minivans are build on expanded car platforms, the GM SUVs are on a crossover specific platform that is unibody. Its not shared with any cars. While they lack the interior room of a minivan, they have more room than any comparably priced crossovers from HOnda or Toyota. I am willing to sacrifice 30 cu ft of cargo space for the styling of the Acadia.
  • 14871487 Member Posts: 2,407
    everyone knows that minivans offer the most efficient use of space so I dont see why you are singling out the GM crossovers. If the Sienna makes them look like bad deals, what would you say about the Highlander, Pilot, CX-9, etc.? Like it or not people do care about style when it comes to family haulers. If all they wanted was space, no one would buy crossovers or traditional SUVs.
  • nippononlynippononly Member Posts: 12,555
    1487, you are as so often occurs, jumping into a dialog without reading what it was actually about. Please don't be so defensive! I was not singling out anyone, I agree that all crossovers really are is minivans disguised to avoid the "minivan stigma" (with a consequent loss of interior space), and the new GM Lambdas are very competitive in the world of large crossovers.

    I was merely responding to the notion that Toy/Lex does not offer a competitor to the Lambdas, by saying that it does, it is just still styled to look like what it is, a minivan (the Sienna XLE in this specific case).

    I read that crap a few weeks ago. The Lucerne performed nearly as well as the Maxima and Es350 but its test score was MUCH lower than those cars. There is no explanation for CR's subjective test scores and it urks me to no end. How can two cars with similar performance and ratings end up with wildly different scores?

    Stability is available on the CXL with V8. CR apparently doesnt get that the CXS has a sportier suspension than the base model lucerne. I dont think the CX or CXL are dangerous by any means, they just have softer suspensions. I doubt its any softer than the ES350's.
  • 14871487 Member Posts: 2,407
    I'm not being defensive, just realistic. YOu and I both know that people looking at SUVs generally dont want minivans and thus the REAL competition for the lambdas would have to be the much smaller Pilot and Highlander. The vehicles are priced similarly and have SUV styling and are direct competitors. If space was the only concern, everyone would be buying minivans as opposed to Tahoes, Pilots, Muranos, Suburbans, etc. Space is obviosuly not the top concern for most people looking for a 7 or 8 seater because the minivan segment is not growing while crossovers are exploding.
  • bumpybumpy Member Posts: 4,425
    Ford killed the CVT option with the Taurus/X refresh. I don't know of anyone touting CVTs as mileage champions; their primary benefits are simplicity, lower production cost, and far more flexible "gearing" arrangements.
  • fezofezo Member Posts: 10,386
    You'll pardon my saying this but, man, has an awful lot of space been used on that one little comment about the transmissions. I'm not calling any body's posts irrelevant or anything like that - just saying we look to be getting stuck on it.

    I really think that like the 8 speed Lexus, etc. the GM announcement is a little bit of PR to say they are on top of it. Nothing wrong with that.

    if no benefits to mileage than who cares? I have read nothing suggest that CVTS are cheaper. NIssan is pushing them bigtime, but everyone else seems only mildly interested. They actually sound annoying to me, I dont want my engine at 5000rpm all day long.

    > has an awful lot of space been used on that one little comment about the transmissions.

    I understand your comment. But I believe the continual drumbeat of "GM shoulda this; GM shoulda that; I knew they shoulda done this 10 years ago; I knew they should not have done that 10 years ago; why did they do it?" always goes on. I find for the motors I've had the transmissions do just fine. I find that the Edmunds Inside line has the expected dig at serviceable transmissions just because someone has gone to 10 speeds, then that's the only thing anyone else should be developing.

    I agree with the comment if it doesn't appreciably affect gas mileage, who cares. Six speeds will most likely cover the motors with less of a flat torque curve.

    I see the same thing going on in another discussion. Anything the company did, plans to do has to be right at the competition that's envisioned in the poster's head. Then when the product is aimed at that exact competitor, the drumbeat will be "It's not good enough. The competitions has a satswatch and this new product doesn't."

    End of rant and it's not at the poster Fezo. It's at the whole concept of Edmund's themes and CD's themes from their testers experts who think the only cars people want to buy are 150 mph, 0-60 in 3 second hot rods.

    Couldn't agree more, time to move on!

    BTW, the auto tranny failed on my '90 Sable at 93K miles (I lost 4th gear).

    No other tranny failures in any other cars I owned except the clutch on my '75 lemon Rabbit at only 13K miles. I wouldn't count the clutch at 220K miles on my old Volvo 240! Clutches have to wear out eventually, like brakes and tires.

    But the '77 Impala I bought used at over 100K miles had the transmission rebuilt by the former owner in the 60K range.
  • imidazol97imidazol97 Member Posts: 27,690
    >220K miles on my old Volvo 240!

    Aren't those supposed to be 500K mile cars!!! :blush:;) Just kidding...

    Back in '77 (before my time) weren't auto transmissions a high failure item? Noone drained transmission fluid regularly. It was supposed to be lifetime and lifetime was usually befoe you hit 100K miles.

  • 210delray210delray Member Posts: 4,721
    I did replace the clutch and had the car for a few more years and a total of about 245K miles. And that mileage was spread out over 23 years (21 years in my hands). ;) It was still running when I sold it. But they don't build Volvos like that anymore.

    I can remember problematic automatic trannies. My uncle's '62 Pontiac Catalina (bought used) always seemed to be in the shop with tranny woes. In the same vein, I remember the TV repairman at our house for multiple attempts to fix the old black-and-white.
