#409 of 732 RX 300 Transmission Problems
Mar 20, 2010 (7:15 am)
I had a 2000 RX 300 and my wife had a 2001 RX 300, both AWD. One transmission went out at 85,000 the
other at 101,000. These cars never towed anything, never had a teenage driver and were never driven off road.
Shame, shame, shame on Lexus for such a piece of junk.
These transmissions at $5,000 plus each are a rip off.
I hope some lawyer does a class action lawsuit.

Were I in your shoes I would only consider a 2002 RX300 if it were ONLY FWD and already had the extra ATF cooling radiator. My 2001 F/awd has the extra cooling yet at only 40,000 miles the ATF smelled and looked quite burned. Did two sequential drain and refills and now at ~80,000 miles and watching/checking ATF condition often.
Overstressing of the transaxle was resolved in the RX330 series by dropping the viscous clutch for F/awd models and adopting DBW to prevent the engine form producing torque before the gears were fully and firmly engaged.
But that "fix" came with its own set of problems.

I have read many times NOT to flush the transmission but to just do a drain and fill. Flushing seems to have caused more issues than they have helped.

Thank you very much for all of the information posted to my question. At this point I'm not sure what to do but I appreciate everyone's postings.

I don't know if there was a connection or not but I had my transmission flushed for the first time a month or so before it went out. I have a '99 AWD
#414 of 732 Now on third transmission
Mar 21, 2010 (9:39 am)
2000 RX300 AWD, now on the third transmission. After the latest transmission was installed in August 2009, we took a sample of ATF via the dip stick tube, using a large syringe and 3 ft section of silicon tubing. Sent the sample to AOA in AZ for spectroscopic analysis. Now at 7 months, wife suspects the third tranny is eating itself alive, as in the first to occasions. Sent another ATF sample to AOA 3/20 and will report back to the forum. Lexus paid for all of the expenses on #2, since failure was reported and documented by dealer prior to the one year warranty expiring.

You could probably extend the life of your next RX300 transaxle by providing a little DC, Direct Current, bias to the ATF line pressure control solenoid. That would raise the average pressure of the line pressure but you would need to be sure and add an external ATF cooling radiator and drain and refill the ATF on a regular basis, say every 30,000 miles.
#417 of 732 LEXUS RX 300 Transmission Failure
Mar 22, 2010 (9:46 am)
Lexus to save cost, made many of the transmission parts out of aluminum instead of steel. You don't have to be a rocket scientist to figure out that it took Lexus three
years of problems to change back to steel gears etc starting in 2003 model RX.

Save costs or weight to improve FE...??
With FE improvement the EPA & CARB get involved in the switch back to steel.
