To my recollection, our 99 RX300 has always done this (OD lock out thing until the engine warms up). I assume it is normal and further assume that it was Toyota's weird way to get a cold engine's temps up quickly to normal operating temps so as to reduce cold engine emissions. Cold engines emit more pollutants all things considered. If the tranny stays in 3rd gear the engine will rev higher and heat up quicker. What do you think about that theory?

I beg to differ. Inability to upshift into third without exceeding 4000 rpm is not normal. None of the above applied in my instance. I guess we'll just have to agree to disagree.
I'm with you on the disagree with it being normal but all things considered so far it only seems to be affected by the cold driving, once it's warm it functions normally. I guess if all I have to do is simply let the car warm up and it's indestructible in the snow, ok.
May I ask what applied in your instance? I'm curious!
Please have the problem of running lean (Fix root cause of CEL) and most likely your limp mode will go away.
The lean issue is a touchy one isn't it? The common solution normally seems to 1. check the gas cap 2.replace the oxygen sensor but,,,
I've found the car to frequent the check engine light around fuel changes. Mine apparently doesn't like going low and will punish me for it. It is also more apt to go on and stay on for longer periods should I be using a cheaper grade fuel & let the level go low in the tank at the same time.
Once the light stuck so I used injector cleaner and premium and just like the manual says, 3 starts and shutdowns and it's right, it eventually goes off.
I'll wade in on this topic as my RX300 has begun to exhibit the same behaviour. It won't shift out of 2nd until the engine warms up a bit. I have to drive about a kilometre at 80 k/h and just above 3000 rpm. before it will shift down. Raising the rpm or lowering the rpm doesn't bring on the shift. This is definitely not normal. I changed the fluid and cleaned the filter this summer in anticipation of the problem. I made no difference. I have 280,000k on the car.
I've been reading a Volkswagen forum where changing a temp sensor in the tranny corrected the problem. (See the link) It seems to be a much more common problem with VW (Ya think).
