No, I think you were right about the TSB, because I was reading transmission threads and someone had some kind of "low speed shift issue" TSB done that fixed some of his problems. Just want to make sure I am not missing something I need to have done to the car, but all the official records I'm finding have no mention of anything else. Guess I'll check with the dealer one day when I have some time.

The 04 has the same color scheme as mine. Be sure any 04 TSBs have been done -specificially the trans and fuel fill tube. If the fuel fill TSB hasn't been done, ask to put gas in the car on the test drive. If the gas pump keeps clicking off when on full flow and you can't get it to work well after moving the nozzle around, it needs the TSB. Not all cars have the problem.

NOTE: • If Calibration ID matches "Previous Calibration ID" as shown in "Calibration Identification Chart" above, proceed with flash reprogramming.
• If Calibration ID matches "New Calibration ID" as shown in "Calibration Identification Chart", this vehicle has already been reprogrammed.
3. If ECU calibration ID is not the same as the "New Calibration ID" listed previously, proceed to Flash Reprogram ECM (PCM).
FLASH REPROGRAM ECM
CAUTION: When reprogramming the LS 430, 12.01a production version or later MUST be used. Using any previous versions of software for reprogramming may result in IRREPARABLE DAMAGE to the ECU!
NOTE: • If the "Check Engine" light is ON when ignition is turned back on to begin the reprogramming process, a scan tool cable problem exists. Refer to TSIB No. SS003-01 , "ECU Flash Reprogramming Error Message ."
• When reprogramming the LS 430 for this issue, calibration files for 2004 and 2005 model year cannot exist on the same Diagnostic Tester Program Card.
If necessary, delete previous calibrations from the Diagnostic Tester Program Card before downloading the new calibration file.
• With this calibration update, 2004 model year vehicles are updated to 2005 model year logic. When diagnosing powertrain-related M.I.L. "ON" or performance issues, refer to the 2005 LS 430 Repair Manual for both 2004 and 2005 model year vehicles.
• 2004 model year vehicles require VIN registration following reprogramming to prevent M.I.L. "ON" (P0630).
1. Disconnect the radiator fan connectors, and connect a battery charger to the vehicle's battery. This will avoid voltage variations that can permanently damage the ECM (PCM) during the reprogramming process.
2. Follow the procedures outlined in TSIB No. SS001-01 , "ECU Flash Reprogramming Process ," and flash the ECM (PCM) with new calibration file update.
3. Reconnect the radiator fan connectors, and disconnect the battery charger.
4. Enter the required information on the Authorized Modifications label and affix it to the vehicle at the location shown in Fig. 2 . The Authorized Modifications label is available through the MDC, P/N 00451-00001-LBL.
5. Enter VIN of vehicle in ECM memory. Refer to procedures outlined in TSIB No. EG012-04 , "Entering VIN During ECM (PCM) Replacement and/or DTC P0630 ."
6. Start the engine and warm it up to normal operating temperatures before test-driving.
7. Perform a thorough test drive with several accelerations from a stop with "light throttle" application until proper transmission shifting is verified.

So the car would only have the problem if the trans is shifting rough? Both cars are CPO (yes the 04 with 25k is CPO for $26k ![Big Grin](https://www.clublexus.com/forums/images/smilies/biggrin.gif)
). At this point both cars are within $500 of each other, so it's not really a cost factor. I really am leaning towards the 04 because this is just like getting a brand new car. The paint just looks so deep and rich in the photos
. Idk, I will drive them both and make an evaluation then. I will set aside year and miles and just focus on how each feels to drive. I will pick the one that feels the best to drive (no squeaks or rattles, quiet, no vibrations at speed, etc).
Similar cars can feel very different. For example, we were actually testing out a 3 series for my mom. The first one we drove had a ridiculously heavy steering, way heavier than the one in my 3 (I swear it's the closest I ever got to a Countach/Diablo steering feel lol, genuinely heavy). This one also had squeaks and rattles. We then tested another identical car, but the steering felt much better and the car was free of squeaks and rattles. All these cars are built within very specific margins, but margins nonetheless. Some better built than others. I really hope the choice will be obvious lol.

Oh yes just a quick potential question:
If I do end up picking up the low mile 04, would anyone be willing to swap their 18in 5 spokes (preferably non-chrome) in good condition for my 17s? You will get a softer ride with 17s. Willing to pay cash on top of the trade. Pm me if you're interested...

I think the car might have the problem if you experience any erratic shifting at low speeds. The good thing is it does not sound as if this is an inherent mechanical problem in the trans, just a programming issue. So even if you do find something strange, you can ask the dealer to have the TSB done first (make sure you print out the above and take it with you). I certainly wouldn't discount the car over it unless the dealer doesn't do what you want.

I paid $29k for my UL '04 CPO with 16k miles and a rare color combo late last year. I would totally jump on the '04 for $26k if it's really CPO and everything is right and as you like.

the '04 LS430 only had two recalls, the transmission and fuel pump. Everything else were TSBs. I had the transmission shifting TSB done and it worked wonders. It was free because it fell under some Federal Emissions rules that is covering a vehicle for 8 or 10 years.

Hey guys, sry to revive my old thread, but I figure this is better than starting a new one since this is semi-related. I have had my 430 for over a week now and put roughly 850 miles on it already (b/t coming from dealer, going to school and back 2 times, and just fun pointless driving). I am absolutely loving the car, it's really a dream to drive.
Now, my parents loved the car so much they are looking to get one. I found one on autotrader. It's an 04, silver on ecru (yeah it's got custom lux), and cpo with 40k miles. They're asking roughly 28k, which I feel is a bit high. Both the car fax and autocheck show the car has never had an accident before. The service records look decent, the owner was definitely pretty picky so that's a good sign. Still need the 40k miles service though, which is something I will try to get the dealer to do. Could you please tell me what you guys think? You have all been so helpful on my car. I know generally what to look for, but I would like some skilled second opinions as well. Thanks again guys!
