#485 of 1381 Drive train by jragosta1 Jun 22, 2004 (7:56 am)
You can't read too much into the fact that the specs on the Toyota and Lexus engines are the same. For example, Lexus uses a drive by wire system that is at least part of the problem. Also, the transmission programming is apparently different. As evidence, consider the fact that it's been reported that Canadian 330s don't have the problem - because they're not certified as ULEV vehicles and have different transmission programming. I read that one person had demonstrated that they could fix the problem on a US 330 by installing the Canadian transmission logic - but this voids your warranty.   There's more to the drive train than just the specs.

I also noticed quite a bit of duplication in entries (same tracking numbers). I went through all 107 entries and only came up with 20 that were definitely related to the shifting/trans problem. And perhaps another 15 that could be related (cruise control, etc)... which adds up to perhaps about 35 entries (not counting the duplicates). Also, Lexus sold about 20,000 ES300 or more in 2002.

I believe you support your argument very well. Your posts are clear and back your assertions. I agree with what you have summarized. Lexus is not owning up to the problem. I have seen complaints from other web sites also.( I do not remember which ones they are on off the top of my head, but I will post them as I remember). I believe some Lexus owners are in denial. They do not want to admit they have made a bad purchase. Buyers remorse has turned into "Buyers Denial". I am not referring to anyone one specifically, just in general.

There are many categories that can be linked to the problem. For example, 'Power Train', 'Automatic transmission', 'Vehicle speed control', and so on.   I don't remember the exact number, but I came up with over 100 for 2002, 2003, and 2004.

Replying to: georgeb7 (Jun 22, 2004 10:37 am) I've tagged in over 10K miles on my 03 ES and have not experienced any hesitation or surging. I don't drive aggressively but did have to floor the throttle a few times and it sped up just fine. I did sense some minor shuddering occasionally though when I gently press the gas pedal after coasting the car bit, kind of like it's driving over a mild uneven road. It does not happen a lot, and when it happens it does not bother me at all, as it's very gentle. Overall I am very pleased with ES smooth quiet ride. Not a sporty one for spirited driving for sure, but a very comfortable car. Just an ideal luxurious family sedan to me. That said, if I ever sense some jerking behavior I'll not be blind/quiet to it.
#491 of 1381 Flush the tranny or not?(94 ES300 110K miles) by questioner Jun 22, 2004 (3:21 pm)
I was planning to flush the tranny on my 94 ES300 recently. But the service consultant at local Lexus dealer suggests me to do a tranny service (drop oil pan and change filter) instead of a tranny flush because he thinks my ES300 is too old with 110K miles to have a tranny flush. While my tranny flush still looks pink and doesn't smell burnt(I bought it used in 2002 so I don't know whether the previous owner had flush the tranny before or not).What's your guys opinion on this? Should I go with a flush or just a service?
#492 of 1381 Transmission by jragosta1 Jun 22, 2004 (4:34 pm)
I would go ahead and have a complete tranny service done. 110 K is a lot when you don't know what the service history is.
#493 of 1381 Flush the tranny or not?(94 ES300 110K miles) by questioner Jun 22, 2004 (7:29 pm)
jragosta1,   Yes, 110K is a lot. That's exactly the reason why the service consultant suggested me not to flush but to do a tranny service. He said it's company policy not to flush tranny on cars with more than 100K miles because it may cause tranny problems since the new fluid may not protect the seal as well as the old fluid does.

Replying to: questioner (Jun 22, 2004 7:29 pm) That's something new to me not to flush tranny fluid just do a tranny service for car over 100k miles. Typical if you do a tranny service you got about only 1/3 of the fluid out the other 2/3 stays. New tranny fluid should be better than the old one, doesn't make sense that new fluid won't be good for old seal. Anyway, if the fluid color looked and smelled good maybe you don't have to flush it. My 97 Avalon has 122K miles on it. I never flushed it only changed fluid very 30k, doesn't have engine oil gelling problem. Car still runs as the same as it was new.
