    Car and Driver magazine (www.caranddriver.com) tested the ES300 in August 2002. They state that the new ES300 has the five speed U150E transmission. The previous generation ES300 has the U140E four speed transmission. I am not sure what transmission is in the RX300.
         C&D states that the U150E contains revised clutching which allows for two overdrives. The problem is that it is reluctant to give them up. Toyota and Lexus used to equip their cars with a sport/economy button for the transmission, but that button and the extra lines of software code are gone.
         The Edmunds ES300 board has many entries on the subject.

    I'll pop over to the ES board and take a looksee.

    I'm interested in finding out if what I'm about to describe is "normal" or if it's due to the fact when I bought my RX300, I had them swap out the alloy/Goodyears to the chrome/Bridgestones.

    You'll need to access the Avg MPH function in Info. Set your car with cruise control and reset the Avg MPH by holding in the button.
    Compare the Avg MPH shown with the speedometer (allow for some time to pass to ensure the avg.). I'm off what looks like 1-2 mph, with the speedo showing higher than the computer. Which should I trust more to be accurate, what with the swap of tires, even though they're the same size? (The Bridgestone *looks* bigger to me.) TIA for those who care to feedback.

    I have a '99 with Michelins. Original wheels and I noticed the same thing. (At least I think it was the same bias. I posted this question here about a year ago and never got a comment. I know it was off 1-2 miles/per hour in one direction or the other.) I did the test on a long, several hundred mile, flat stretch of highway with the cruise control set at 70.

    In my post #6801, I mentioned that I do not know what transmission is used in the RX300. I did a Yahoo search on "RX300 U140E transmission," and it appears that the U140E is used in the FWD RX300, and the U140F is in the AWD. Since the previous generation ES300 used the U140E, and the 2002/2003 ES300 now use the U150E, there is a possibility that the new RX330 will also use the U150E.
  • Had the 5k service at the dealer which is 1 1/2 hours away and took 2 1/2 hrs. Since then, we use local Toyota dealer, use mobil 1 and no problem. Check engine lite and VSC lite came on! Lexus told us it was probably loose gas cap and it would reset itself in a week. After 3 weeks, took it in to Lexus who found a loose evaporation hose, blamed it on the Toyota service and told me they would charge me next time, that this is not covered under warranty. Would someone please tell me what bumper to bumper warranty entails??? Did I just go to a dealer who just wants to charge exorbitant prices because I haven't been servicing the car there?

    The RX300 needs a 5K service? Is that just an oil change or do they do other things too. I guess that makes me more glad I opted for the QX4 last year. Another thing I am wondering is why do you not like letting them do the service? I understand it is 1.5 hours away but couldn't you incorporate it into a shopping trip or something. I assume they give you a loaner. I am also assuming they are open for you to do it on Saturday. Well, I guess if I had to travel 1.5 hours every 5k miles, that would not be to swift. I use Mobil1 in my QX4 too but take it 7500 between changes.

    For those with Kazaa and broadband, do a search for a video clip entitled "2003 LA Auto Show - 2004 Lexus RX330"

    The reason toyota made a luxury division was because they knew people in the USA are into image and no one would buy a 40 thousand dollar toyota. So when it comes down to it, I think lexus has nothing to worry about because a lot people are not going to want to put money on a 40000 dollar Volkswagon, no matter how good it is. I like the Volkswagon too, but when it comes down to it, I would rather buy a lexus and have people know I'm driving an expensive vehicle then buy a Volkswagon and just have people think its a nice car. As far as the other competition goes, Volvo, despite its very loyal customers, doesn't have too many of them and I don't think many japanese car owners are going to want to switch. Once you go Lexus, you never go back! The only one car to worry about is BMW. By the way, the metallic trim is on all models not just the sport package equipped ones.

    For those of us who bother to read the RX300 owners manual 7500 miles is the suggested mileage between oil changes. Unless you're using it for Taxi service or for towing your boat.

    If you simply listen to the dealers they'll soon have you down to 1000 miles between oil changes and a complete engine overhaul every 50k.

    That would be, let's see...your 5th Lexus?

    Darn those dealers!!
  • ravlravl Posts: 129
    Thanks for the feedback, Avery. Maybe you're the one that made me think to try this? I guess the next question is which source do I believe more, the speedo or onboard computer?
  • wwestwwest Posts: 10,706
    Dealer gets 5 in April but since I don't want the nav or the sunroof I'll likely have to wait.

    Dealers: Hey, you have to buy the car somewhere, the secret is to never darken their door for anything but vehicle purchases or absolute necessities, like shop manuals.

    Bought my 01 C4 over the internet, Greenlight, have never even met, been at, the dealership. Salesman, Daniel Brunty, was a nice enough person over the phone.

    Looking ahead to the RX180/e that will be an even dozen.

    The speedo is a "real time" indication, use it for that. The OBC computes and displays an average, use IT for that.
  • avery1avery1 Posts: 372
    If I put the speedometer as accurately as possible on 70 and zero out the trip computer, go for 150 miles on flat I5 and have the trip computer read 67mph it just makes me wonder which is accurate. Obviously not critical to have the computer super accurate but it raises the question.
  • Just getting ready to post this when I saw ravl's message above. I (finally!) replaced the Integrities on my 2001 RX with Bridgestone Dueler H/Ls. Haven't taken them on the highway yet (where the Goodyears drifted all over the road), so I'll hold off on any performance comparisons. But the gas mileage (at least what's reported by the trip computer) looks to be about 2 MPG less with the Bridgestones. I hadn't considered the possibility of different tires throwing off the computer. If not that, could it be simply that the Goodyears get better gas mileage? (That might explain why Lexus kept putting sub-$50 tires on a $35K+ vehicle.)
  • wwestwwest Posts: 10,706
    Might be a simple "rounding", or even truncation, matter in the computation of average MPH. That OBC isn't a P4, possibly even an 8 bitter.

    Or the programmer might have been thinking forward to the day that a WSP (Washington State Patrol) wanted to look over your "shoulder".

    Does anybody know how to reset AvMilesGallon on display? I''s stuck on 16mpg and there is nothing in the manual about it.

    Thanks a lot, YG.

    My 00 RX manual says on page 44 that { to calculate from the beginning, push the "INFO" button for more than 1 second. }
  • I haven't checked on tire weights but I'd suspect that ANY of the common replacement tires for the Badyears would be heavier than the Zerotegritys. A greater rotational mass would require more power to accelerate (and brake, for that matter, which is why one should look at upgrading brakes when going to significantly bigger wheels and tires) and would adversely effect mileage.

    I think it's a worthwhile tradeoff, though.
