I have a 2002 RX 300 with 84,000 miles. Last winter, I was involved in a front end collision, which destroyed my transmission. Lexus Dealer installed a re-built transmission. Now I am leaking oil, and they are trying to tell me it has nothing to do with the accident (because they don't want to fix it) I never had any problems with the car leaking oil in the past. Is this a known problem with the 2002's?
