RX series design change, resulting failures, and fixes (non-fixes actually).
When the ATF accumulator was dropped from the Camry transaxle design to make room for building a more robust transaxle for the soon to be released to production RX300 they obviously didn't foresee the problem associated with a need for a downshift for re-acceleration immediately following an upshift resulting from a throttle lift.
So the '99 and '01 RXes, at least the earlier '01's, had premature failures, most likely clutch failures, due to the lack of sufficient ATF pressure when the firmware commanded a downshift for re-acceleration.
My guess is that by about mid-production of the '01 model the mistake/oversight was discovered and the only quick and easy "fix" was to modify the firmware so that the "real-time" "bottom level" control of ATF line pressure was substantially increased.
While this would result in more line pressure being available for that "unexpected" downshift it would also result in substantially more heating of the ATF then had been planned. As a result almost all, if not actually all, 01-03 RX300's were shipped with the towing package which just happened to include an external ATF cooler.
But since the actual heating was restricted to a local area, the ATF pump and "real-time" pressure relief valve, the extra ATF cooling was not of great help. My '01 had ATF that was quite burned and odorous at only 40,000 miles.
When the RX330 (Camry, HL, ES300, Sienna...) rolled off the production line with DBW the transaxle failure problem was finally SOLVED.
Except the customers did not much care for sometimes having to wait 1-2 seconds after gas pedal depression for GO....
The 2010 RX350 now has new firmware to help with the reluctance to GO...

I have a hard time imagining that it's not the transmission if you're having problems with reverse. This same question has been coming up a lot lately, so check out the "search" function on this site for more details. There is lots of information. If your car is otherwise in good shape and worth fixing, you're at an advantage that you're getting some advance warning before something breaks internally or clogs and it fails on the spot.
Since you didn't notice a problem with it until you're long passed the long mfr warrantee, likely you (the owner) are responsible for the cost. But Lexus has been providing other owners with partial loyalty (goodwill) discounts on out-of-warrantee transmission work done by them for established customers or to earn your business. I don't believe they are under any obligation if you had nine years/80,000 miles of use, but I could be wrong. But I also believe if you have an established relationship with the Lexus dealer and you ask, they will try to work with you on a Lexus transmission, especially if you show you asked them to perform preventive service on the transmission which likely was in addition to the manufacturers suggestion.
You may want to share some of your experiences on this site. For instance, how the dealer tries to work with you, how brown/burned is your transmission fluid, how long ago it was last changed, etc. Good luck, and let us know the details.
#208 of 732 Another RX300 Trans bites the dust
Mar 20, 2009 (10:59 am)
I have a 2000 RX300, i am the original owner and have always had it serviced as supposed to. It has 77k miles.
As i was driving near my home my car just stopped and would not go into any gear. I just had it in a lexus dealership for a quote on the knock sensor two weeks prior.
I have mentioned several times to this dealer and a dealer in another state that the transmission seemed to slip periodically (about 6 times) over the last 2 years while going into reverse. And now i see these posts and am furious. They all acted like they had no idea why it would be doing this and did not even recommend i have the transmission looked at.
I see what seems like lots of folks getting help from Lexus and from the dealerships in offsetting the cost of the new transmission. Has anyone been refused assistance?
Does anyone know of any OTHER shops in milwaukee area that will give me a more reasonable quote should i decide not to spend time fighting with Lexus?

If it was me, I would stick with dealing with a Lexus dealer on this issue, even if you get better results by going to a different Lexus dealer. I would recommend remaining calm and polite, yet firm. I would show the Lexus rep that you've been requesting assistance with the transmission all along and that the response you recieved was to wait for it to suffer a common failure. Lexus had issued many TSB (technical service bulletins) on this issue.
"Normal" service does not include the transmission until failure, as you've undoubtedly read or found out by now.
I'm not the biggest advocate of any brand's dealer service. However, in your case I'd stick with Lexus on this issue because it's likely they will help you if they feel it's in the interest of continued customer loyalty. Also, the transmissions sourced from Lexus are more likely to have updated hardware (better than original) than one sourced from a third-party transmission shop that was rebuilt with aftermarket parts. I'm guessing you don't want to spend a few thousand dollars and risk having the same trouble again in a couple years. My new Lexus transmission is great, after having it replaced under warrantee. And the new one does not show wear in the fluid (burning color & smell) like the original did. I expect the replacement to be much more durable.
Please report back and let others know how you were treated and how it worked out. Hopefully, Lexus will agree to pick up the tab for a good percentage, bringing your cost into reason. Good luck.
#210 of 732 LEXUS TRANSMISSION DEFECT
Mar 21, 2009 (11:38 am)
Lexus RX300 4WD purchased new, dealer serviced. Right after being serviced at dealer for 80K service the transmission failed, totally. Our family has owned 100 assorted cars and trucks over the last 50 years, 5 Lexus, and never had to replace a transmission before. It is bad enough that Lexus dealer charges $400.00 for a replacement HID head light bulb, but $5,500.00 for a transmission seems crazy, and typical. My 100K Lexus extended warranty would not cover it. The Lexus RX transmission is a defective product! Study all the thousands of Toyota transmission failure reports out there, these should be replaced at no charge, or a class action lawsuit started. Another unhappy Lexus owner stuck with two 2001 RX300's doomed to sit on the side of the road and strand the owner.

"...Lexus extended warranty would not cover...."
What excuse was given for THAT...??
Mar 23, 2009 (9:28 am)
I was a bit surprised too when I read that statement. I have '02 RX300 with around 85K miles on it and in the middle of 100K extended warranty.
When I purchased the warranty, there were two kinds of warranty. One regular warranty and other full warranty, obviously expensive than the first one. I opted for the second (full). Hope the above statement refers to the regular warranty. If not, I will have to double-check with my dealer who said everything is covered (except battery, etc).
Please check once again what kind of warranty you have!!
#213 of 732 2001 LEXUS RX300 TRANSMISSION PROBLEM
Mar 25, 2009 (8:55 am)
I have owned 5 new Lexus vehicles including two 2001 RX300 models, and all were well maintained at the local Lexus dealership. However, the RX300 seems to be problem prone. This was purchased new with an extended 100,000 warranty and right after the 83,000 mile service at the Lexus dealer a serious transmission problem developed, making the vehicle unusable. While these type of problems might be expected with a KIA or Chevy, I would assume that a serious drive train problem would be extremely rare for a Toyota product that has always been professionally cared for with expensive dealer service. This is the 2nd time the transmission has been an issue. The first defect being caused by a defect in a critical motor / transmission gasket seal.
I am extremely unhappy with the fact this was not discovered during the road test, and that Lexus will not warranty or support the defective transmission product. Chronic and expensive transmission problems represent the weak link with Lexus RX vehicles. I have lost faith and piece of mind in both the product and Lexus customer support structure which offers nothing to the owner. I am now ready to join the Lexus class action lawsuit.

You mentioned that your vehicle was under extended warranty. Did the warranty cover the transmission problem you are talking about?

I had a 2000 Lexus RX300 module, recently I just got rid of it, because this was the second time that the transmission failed on me. The first time when the transmission failed, I was driving the vehicle on the highway, and I felt some thing wrong with the car, so I exited the highway, suddenly the car stopped on me when I was exiting the ramp. This would have caused a big chain accident if I was continue driving the car on the highway at that moment.
I suggest all the year 2000 Lexus RX300 owner, carefully check your transmissions with your mechanic. Do not drive on the higway unless you are sure there is no problem with your transmission.
