2 Questions- Cold Start Up Idle And No Overdrive

[94 es300]

I have a 94 es300 55,000 miles on it. No codes are coming up Cars runs great I have 2 questions.

1. Last night the Temp. here got down to 45 Deg. when I started the car I assumed it would idle high for a period of time then reduce to normal. What should the cold start up idle be? It didn't idle any higher than it normally does.

2. The car would not shift into overdrive on the way to work. It is a 15 mile drive on the interstate at 70 miles per hour. On the way home no issue. I would certainly think some where along the way to work it would have warmed up enough to shirt to overdrive. This is the second time this has happened in the last week.

- What is "cold start sensor?" I haven't heard people in this forum talked about it.

- I have the same problem and I can't fix it. Someone here said it is normal. Pay $100 for Lexus dealer - They said the same thing. I hope it help.
