My wife drove our 01 RX300 untill it stalled due to engine overheating (blew a hose, now fixed) Since overheating, I have a check engine lite for both knock sensors out of range and the car wont shift into fourth (overdrive). The check engine lite was easy, both sensors were heat damaged. But the trans is giving me fits. I have switched cars with her for a few days (lucky women gets my 470. lol) to monitor the exact situ. It just stays in third as if THAT were top gear. Occasionally, like maybe three or four times out of the last fifteen outings, it shifted normally untill it warmed up, as if the colder thicker fluid fixed the problem. Got me pretty excited untill it fully warmed up then stopped at third gear again. Today, it was perfect for first thirty minutes, thirty miles of traffic untill I stopped for coffee. As soon as I restarted it, it was a three speed again. Any ideas?? Thanx guys

Im a new owner, and unlike my usual m o, I decided to read BEFORE attempting to put a starter in my 98 470, especially as I couldn't even FIND the darn thing. So I searched in this forum, "where is starter" and the third or fourth find was a person who had the same question, did the job, and did a 13 step write up. He said it took him 6.5 hours, but knowing what he now knew, he could do it in 3. Well, using air tools and more important- write up in hand, I did the jod in less than 2 hours. Including reading, putting away tools, and a test drive to QT for a XXX Vitamin Water as a reward, I'm done and tools are away IN 3 HOURS FLAT. This forum, and the owner who took the time to do the write up- ABSOLUTLY ROCK :D
