I traded a 2004 ES330 for an 05 LS430 because of the jerky transmission shifting. The LS isn't much better, at a slow roll, shifting is very erratic. Again, the mechanics say it's "normal". For $60K the transmission (or computer that controls it) shouldn't be "confused". Sadly, my $15K Dodge pick-up shifts much better (seamless) for a fourth of the cost. Big disappointment.
Navigation system and Mark Levinson stereo are awesome.
Fix the transmission shifting, or get rid of the computer controlled shifting and go back to the 90s, when the cars were smooth!
