We have had the exact same issue with a 1999 RX300 that we bought used. To save yourself a whole lot of anguish, before you have ANY repairs done, have the check engine light coded to see if your knock sensors are bad. Our Lexus would not shift into overdrive, the engine light would stay on, and would take off sluggishly, had poor gas mileage, etc. The Lexus dealer diagnosed the code was a bad knock sensor, one of the service advisors said this would cause the transmission problems,another service advisor (same dealer) said it would not, so we took it to Aamco. The price for aa new trans was considerably less at Aamco, $3000. vs.$6000 Lexus. Aamco put in new trans and the next day the light came back on. The transmission would still not go into overdrive. It was exactly the same as before we replaced the trans!!!! We replaced the knock sensors and it did fix the shifting problem, bad news is, a few weeks later, light is on again, and codes bad knock sensor, bank 2. We did research online and found out there was a redesign on the wiring harness for the knock sensor and we had to tear the intake off AGAIN!! Do not buy a trans,before checking this out. I wish we had known all of this before. Knock sensors are $500/parts,$400 labor. Good Luck!
#34 of 732 THANKS FOR FEEDBACK
Jun 02, 2007 (4:19 am)
I originally posted this thread and now that i have seen the feedback from others, i think i will be buying a new non lexus suv instead of holding onto the one i have. It now has 88k miles on it, still running like a top,but the repairs described by others are shocking my system. I have had 4 other Lexus autos in the past and they all ran like new right up until I sold them,but I'm not taking a chance with this one, especially with my wife driving it on local 2 lane rural roads in the middle of nowhere, AAA notwithstanding.
THANKS FOR ALL THE FEEDBACK!!!!

Were I you I would buy my wife a good cell phone, presuming it to be viable on those rural roads, and keep the RX300 until it breaks, if it ever actually does.
~$4,000 for a rebuilt transaxle is lot cheaper than a new Acura RDX or BMW X3.
I fully intent to keep my 2001 AWD RX300, now at 65,000 miles, until it breaks, even until 200,000 miles. At that point it will get a DIY rebuild and a PTO modification to covert it to "solid" RWD and with (only) VC coupling to the front.
Not altogether sure I'll wait much longer before doing the PTO modification, maybe before the next snow flies.

The code was something to do with cellonoid (Spell??) PC165??. AAMCO opened up the transmission and they said it was shot. Apparently something had clogged up and the transmission fluid was not being circulated (did not go back and forth from the external cooler?) and got burnt up. AAMCO quoted me the same as Toyota Dealer ($4550) to rebuild the transmission since they said a lot of parts have to be replaced along with the external cooler which it self is nearly $400. I have no choice now because if I pull out the car from AAMCO I have to pay $785 for the labor so far. And then I have to take it to the dealer and get it fixed. I went ahead and asked AAMCO to fix it. They matched the dealer warranty (1 year, unlimited miles). I asked for 3 year, 50,000 miles but they would not agree for that. So, so far in three months since I bought my 2000 RX300 I have (would have spent) $5,227 and I had paid $12,000 for the car. So, brand new cost, $17,227 for a used 2000 RX300 with 85,000 miles and I am not sure what is next? The 90,000 miles service will come up (if this car runs until then!).
I will check in the knock sensor code and see if it also was listed. Thanks for your advice.
Sorry to say this, but nothing but bad luck so far. Hope you guys understand my frustration!!!
#40 of 732 Yet another RX300 tranny problem
Jun 11, 2007 (10:44 am)

#41 of 732 Cheaper here in Brooklyn NY
Jun 18, 2007 (1:58 pm)
I got my RX300 1999 with 103,000 of mileage. I didn`t really pay much attention to some delay when on reverse after having warmed up and some delay when shifting from 2 to 3. Now it doesn`t shift to 3 at all, so I have to drive at DR2 fixed. But the reverse hardly moves the car now and the engine revves up. So in the transmission shop here in Brooklyn NY, they said it would cost me 2500 plus tax, wich comes to 2700 fixed to a new condition. Which is a good deal after I read all of these posts. I was advised not to buy one used on-line myself, since there is no guarantee it has a mileage they say it has, and that it`s in a perfect working order. So I have to shell out and have it fixed in a russian transmission shop. Oh, also, the engine light came on and after having been coded it said-the solenoid B malfunction, so the mechanic said it might solve the problem. I got it replaced for 470$$, but nothing has changed. Not it adds up to another 2700$. I checked on-line searching for a used tranny and was shocked-how much cheaper other trannyes were compared to Lexus RX300. Even Acura MDX`s cost 1500$$ straight up compared to 2500 of Lexus. And for that price there is no guarantee it`s gonna work as new. They say they provide a carfax report, but I think that`s a big deception, a trick to get me pay. How can it be only 30k of mileage? What, it`s been sitting on a shelf waiting for me in the recycling shop all these years??? I strongly doubt it.
