I had the same concerns when I purchased my 2002 LS 430. I spoke to other owners at the dealership. All said the same thing, "don"t worry about it".
 
I live in Cleveland where it is snow on top of ice on top of chuck holes.
I run the tires it came with, summer tires, push the "snow" button on occasion, and drive off. The LS handles better than my wife's Honda CR-V, but not as good as my 2003 ES 300. In any event, don't worry about it.

#12 of 16 Transmission Flush??? by ls96

I have a 96 LS400, 154,400. 2nd owner, purchased at 98,000 miles. Have not had to do any major maintenance only oil changes. Was recommended last oil change that I needed a transmission flush due to dark fluid. I have been getting mixed opinions..most friends say don't???? Any opinions/recommendations. I'm confused? thanks.

Hmm...second owner...
 
Abusive first owner, used as a taxi, or for towing..??
 
If the ATF actually is dark it might also smell burned in which case a flush would be appropriate.
 
Check it yourself, it should be pink and transparent.

#15 of 16 Drive train question. by wwest

Nov 17, 2009 (5:26 pm)

'92 LS400 with 155,000 miles. Runs perfect, just passed WA state emissions test with flying colors. driving along at ~40MPH there is a rare "tug" feeling, and sound, as if the brake were applied just for an instant. Cannot readily duplicate. Sometimes "tug....tug...tug" and it seems anything I do, change, (a little less throttle or a little more, etc, etc) and it goes away
 
Car pulls STRONG, transmission seems to be fine, shifting okay, etc. ATF okay.
 
Suspecious of trac system triggering briefly and haven't had a chance yet to run with it turned off. Will also try running with OD off.
 
There is only one U-joint in the drive/line, shaft, anyone had one fail in this manner..?

Problem turned out to electrical. The ignition timing sensor wiring from the driver's side engine bank was just barely "touching" the accessory drive belt. Shield braid was worn through as was one of the two sensor wires. Don't now understand why the engine ran at all. Especially don't understand why, as much as I drove the car in the TDCL check mode, no sensor error was recorded.
 
Looks as if the mechanic who replaced the timing belt missed putting the sensor cable back into the restraining clip.
 
Lesson....
 
If it ain't broke don't FIX it....
 
The nice aspect of all this is I inadvertently discovered a way to "fix" the traction control system. The major complaint I have had in the past is how long it takes to "unwind" the dethrottling aspects of the TC system and regain control of the engine RPM.
 
There are two screws that hold the (separate) TC throttle plate in place and I simply backed them out and removed the TC throttle plate. Now when/if teh TC activates the engine will no longer get dethrottled at all.
