This makes sense, but for Toyota, meeting federal regulations is of prime concern. Transmission longevity is secondary. Needless to say, the fast idle when the engine is cold is not good for the tranny, period. Apparently, the transmissions can take it, at least for a while, but in theory, it's still not good.
Our Camry revs at about 2000 RPM as well and then slowly drops. Even my Hyundai Excel did that.
Yes, this is fine for cold start up. But I'd like to see the idle come down from 2,000 to say 1,200 in about 45 seconds maximum as opposed to nearly two full minutes. I am not comfortable shifting into drive unless the revs are at about 1,300 or less. Any higher than 1,300 or so and the shock on the drivetrain is quite noticeable when you shift to drive, the car lurches forward, wants to speed away, etc. Not good.
The only thing I don't like is how the car wants to race for the first few minutes when driving. When going around town for example, I have to drive down a small hill. However, the car wants to reach 30 when the proper speed limit is 15.
Right, just that much more wear and tear and strain on everything. If the car is racing ahead faster than you want and you need to apply the brakes to slow it down, this is not a good thing. Think about it.
One system that would be good.... start cold engine, engine revs to say 1,800 rpm, within 45 seconds it drops to 1,200 or less. OR, if you shift to drive, the computer senses you shifting and immediately drops the idle down at that moment so shock to the drivetrain is less. An `89 Honda Accord I used to have did this... was excellent.... when cold, the fast idle would drop instantly if you moved the shifter out of park... very smart idea. This way the revs would be lower before you'd hit any gear.. and then once driving, the car would not be trying to speed along faster than you wanted. Too bad Toyota does not do this now. Oh well. I guess they need to do whatever possible to get these cars to pass the super strict federal regulations. It's getting like 1975 all over again.... manufacturers having to do ridiculous things to get the cars to pass. Fortunately though, things are way better now than they were in 1975, so can't complain!
Thanks for your input!
