02 ES300 trans hesitation report

njbok · 2007-04-26T03:00:17+00:00

Some time ago I mentioned that, after complaining to a Lexus service advisorabout my ongoing trans hesitation (well it really became a transjerking-while-finding-a-gear problem after last software upgrade) that hementioned that Lexus had issued a TSB that stated the need for premium fuelafter the upgrade. I doubted it and he couldn't find the TSB. I later foundit online however, and he was right - it did state that. I still had mydoubts about fuel being involved.Some here said that it was possible for the octane level to affect the transperformance. I finally gave in, and have been using premium fuel for thepast few thousand miles, and I have to say there is a big improvement.Yesterday I felt the jerkiness again though - but it was a minor episodecompared to previous ones, and it was the first and only time since Istarted using premium.Now, it's kind of academic though, because I've been looking into getting an'04 LS430. In doing my research on that vehicle, however, I learn that theyhad a recall on those 430s made in '03 whereby the trans is replaced ! Ithought the worst thing on those cars was the air suspension. Now I have toworry about the trans on the LS430 I might buy !Does anyone have any info on the 04 LS430 (6-speed) trans problem ?(I suppose I should have started a new topic for this LS question.)
