Bad Lexus RX300 transmission.

- Northridge, CA, USA

Bought the car used at 145,000 mi. Noticed the car was not shifting into overdrive at about 160,000 mis. Took car the Toyota dealer for repair. After $200 of diagnostics and 3 days they determined the transmission was bad. The car will sometimes go into overdrive and sometime it will not causing the engine to rev to 4000 to 5000 RPM at highway speeds. This is unacceptable performance. I have read how transmission problems on these cars can cause unsafe driving conditions and now I don't know whether I can trust the safety of drivers and passengers in this car on the highway.

The transmission on my 2000 Lexus RX300 went out around 135,000 miles; the transmission was rebuilt in April 2006 and recently went out again around February of 2008. I was recently informed that I needed to replace this transmission again. This is a real sad situation that a luxury car does not last longer than 10 years. I writing because I need some help and or direction in getting this problem solved. I cannot continue to replace a transmission every year. Thanks in advance.

Has to pay the dealer $4,000 to repair. Some owners of the same model vehicle has experienced the same problem.

Transmission on 2000 Lexus RX300 is ruined at 110,000 miles and needs replacement, according to the Lexus dealer. The owner's manual said no transmission fluid changes are necessary, yet with the failure the dealer wrote on the receipt that the transmission fluid had not been changed in a timely manner. Clearly they are at fault.

There is a forum on edmunds.com with postings of a lot of people who are having transmission problems with their Lexus RX300's. I asked for help back in September/October of 2007 and have since had my problem fixed for N/C by Lexus. Apparently others are not as lucky.

2000 rx 300 failing transmission. Started having trouble shifting in low gears when cold, now shifts inconsistently and sputters while idling. Mechanic says we need a new transmission, but I'm afraid fixing the transmission is just treating the symptoms of a design flaw.

2000 Lexus RX300 with AWD transmission had very hard shifts, and wouldn't even shift into reverse. Took it to aamco and they opened it up and told me I need complete planetary set gears, and charged me $1300 to put it back together. Still problem continued, took it to world wide transmission and they rebuilt for $3,400. Now it shifts better, but often with a kick on the downshifts between 2nd to 1st.
