#703 of 1407 Lexus TSB Issued April, 2005
May 05, 2005 (2:46 pm)
I spoke to a service advisor at a California Lexus dealership yesterday who informed that there was a new TSB for the ES 330 line, model years 2002-2005.
The TSB number I was given was: TC 004-03 for "ECM Calibration". I understand that it was issued for April, 2005.
I believe that the transmission in the RX330s are similar or the same as that of the ES330; whether the TSB may apply to you depends on when your car was manufactured.
I hope that this is helpful to those of you who are experiencing hesitation problems with these cars.
#704 of 1407 lexus transmission update

I had the update done on my 2003 es300, on thursday. I can definitely feel the improvement. The car shifts at higher rpm's and also doesn't search for gears at lower speeds.

Please update us after 500 miles. It will be interesting to find out if it has reverted back to it's old ways. WE HOPE NOT!
#706 of 1407 Will This update fix the Avalon '05 too??
May 09, 2005 (12:26 pm)
I have been having the shifting problems detailed in this discussion thread with my 2005 Avalon limited the past month. I bought on 4/5/2005. I have contacted the dealership who says they have no knowledge of the problem. I had diagnostics run on my car and the service department says there is no problem. However, I am still experiencing the same rough shifting, uncertain starts and hang time revving in the lower gears. There has also been dead time after I press the accelerator and when the car moves. The problem is none of it happens on a set schedule. I am wondering if the computer upgrade provided by LEXUS will also be applied to the new 2005 Avalons?? Anyone know??

You may want to check the Engine Hesitation Forum for more discussion on this topic.
There was an article around April 12 in the Pittsburgh Post Gazette that stated that the software fix was for all 2002 - 2005 Toyota and Lexus models with the 5-speed auto transmission. However, as far as I know, the only TSB issued so far is for the ES300/330. Someone (was it you bkinblk?) spoke to their dealership and was told that the software upgrade was intially being tested on the ES300/330 and would slowly be released over the summer, I think, for the other models. Also, bkinblk who posted above was told of a solenoid upgrade/repair for the hesitation problem.
Sounds like Toyota is doing something. If and when it will be applied to the '05 Avalon, I don't know. You could try calling the Toyota corporate customer service number. I answered someone's question in the 2005 Avalon discussion forum in regards to hesitation and the other posters there are pretty sensitive about discussion of a potential problem in the Avalon, LOL, and adamantly insist that the problem does not exist in the '05 Avalon. Could you describe your symptoms in more detail?

USA TODAY had mentiond the hesitation problem when it reviewed the new Avalon. I posted a link in the Avalon forum but everyone dismissed it because they said the Avalon was perfect.
#710 of 1407 ES330 trans. problems
May 12, 2005 (10:15 am)
Does anybody know if Lexus is going to fix transmission problems on the ES300/330? This problem is really annoying to drivers and can be potentially dangerous in heavy traffic. Who would spend 35k-39k for a car like this?
Please advise. Thanks

My opinion is that they will not fix the problem before 2007, Here is why:
1) Toyota does not admit there is a problem.
2) If there is a problem, it does not have an inexpensive solution. Lexus has tried using firmware to fix it, and it does not work, implying a system hardware/firmware redesign, which would be prohibitivly expensive for Lexus/Toyota. The fact that many drivers do not admit a problem does not help here.
3) Lexus owners have been complaining about the problem for three years and no response from Lexus regarding a real fix.
5) At this point, with fewer than two model years to go, I can't see a complete redesign of the drive train system, with Toyota replacing the system in all existing vehicles. I just don't see it, particularly since it has not been verified that it is a safety issue.
As a potential owner who cared significantly about the problem, I would wait until 2007 to see if the problem resolves itself. Even then, if I were a betting person, I'd guess the problem would be there in the 2007 vehicle, for another five years as well.

I agree with atoews on all points.
It may be premature to assume that the recently released updated TSB: TC004-03 firmware upgrade won't be effective. Only time will tell. Based on the prior TSB update released in late '03 which didn't work, I assume that we will see a repeat and it won't cure the problem.
The real problem, imo, is atoew's point #1 "Toyota/Lexus does not admit there is a problem. Owner's have complained for three years and still nothing is done to "solve" the problem." Just band-aid firmware upgrades that attempt to appease the unhappy owners.
I have to agree with atoews that there must be a serious system hardware problem that would be costly to fix and Toyota/Lexus is unwilling to do so in the absence of proven safety problems. Notice that all of the new models (GS, Avalon, etc) are avoiding the same drive train.
The ES continues to slide in rankings against the Acura TL, BMW 3 series, and Infiniti; I believe because of the drive train issues with the ES.
I am scheduled to have the TSB update done during my next service visit. I will share my thoughts then. I will admit that I am biased and not expecting to see much improvement.
At this point, I wouldn't even consider the ES as an option if I was looking to purchase an entry level Luxury sedan. ( I have been a loyal Lexus / Toyota customer and have owned 2 prior Lexus and 2 prior Toyota vehicles ). This experience has been unacceptable for me to be a return customer again.
