Need help about my 2004 LS 430
Got my used 04 LS 430 last month, with 78000 miles ODO
but since last week, I found that once when I was driving on Freeway, I step on gas, but rpm going to red line without speed up......
then this week I found that sometimes transy can't shift into 4th or higher gear......
and when I put shift in S mode, only shows 5 in the screen......

Yes, there was an issue with the 2004 transmission of not engaging into "Park" correctly for some flash or something, not what was described with the "shifting" but bring it to dealer none-the-less to see if it was covered for the other problem anyway. Although one might not have to do with the other, if your VIN is covered and the vehicle was not recalled for the fix, then get it done.
As for the "5" when you shift to "S" that is the first gear it displays when you first shift over. Shift up to go to 6 and down for 4 and then on... So, if you're on the highway and you hit to "S" it's the first downshift so it starts at 5.

...do you think it may be in the wrong gear when this driver who started the post is driving? If not it sounds like a definite transmission issue. Maybe the t.s.b if never taking care of turns into the issues this drivers having.Whts your take AlexusAnja, you have a better ability to relate and give advice car wise because you also own same year. Did sound like he still doesnt know how to use his car in terms of gear selection and may have not been told how to operate this car!!!! Really hope the best for this memebr and hope its covered under warranty!!!!L.G.N.M

It doesn't sound right no matter what... but you're in "full automatic" mode right, just "D" and go and this is happening with the no shifting beyond 4th gear?
As for what the "S" mode displays, I don't think it displays anything beyond what you're currently on, say "5" I've started from a stop in "S" mode with display of "5" and it surely doesn't feel like it's launching from "5" Honestly, I don't know if the "S" modes just retards the shifting to the highest that it's displayed (ie only to 3rd gear if "3" is displayed) but like all shiftable automatics, it will shift up once it's running on a high rpm too long.

When the ES350 was having it's transmission-death issues, this is exactly what you'd see. Misbehaving trans followed by all the warning lights.
In general, trans problems in the LS430 are ridiculously rare events. The only known problems were the very small first batch of 6 speed 2004 models which transmissions were all replaced. That's it.
