ok whenever i start my car and its cold out im fine until i get to where overdrive should kick in. but once there my car will not shift up. after a while of my car running at over 4000rpm and the temp skyroketing it will finally shift up. my dealer says its normal that all toyatas do it, until normal operating temps are met. but it sounds horrible and kills my gas mileage. is this true. thanks.

I've seen some post about that this winter season and it's ok. I actually warm up my tc for at least 2 minutes befor i drive

Mine will want to run about 2K or so until it heats up... But, since I'm a 5-speed, the engine will pretty much do what it's told.

As far as I know, it's normal.

yeah, depends how cold it is. I just wait until the revs stabilize around ~1.2K and I'm off.

my wife's 93 camery does it. your fine.

thats how most auto transmission works. This is for emissions reasons. Logic says less revs when not at normal operating temps..... but I guess world emissions is more important than engines.
The only advice I have: drive slower.

Yup, it's best to warm it up a bit if you need that power. By warming up, I mean driving at city speeds (that's the quickest way to warm up... in my experience, letting your car idle is a painfully slow way to warm up.
