Transmission needs to warm up?????

[bojim]

I'm a first time newbie and glad to be a Toyota owner again. I really like my new 07 silver sadan. I have a question that I have not seen it covered yet, except for one time and it was kind of vague. I'm in south Al and it does get below freezing from time to time (believe it or not) ha ha. This is the first car I have ever owned that during cold weather you have to let it warm up before the transmission will shift properly. In my case 40 or 50 degrees F or below. Is it just me because I think this is abnormal? I read in the manual you have to let it warm up but I figured it would have to be freezing outside to affect the transmission. I also asked the service tech. at the Toy. dealership and he said its normal for Toyotas to do this. I'm sorry but I'm very suspiscious. Can ya'll help me please?
