Tranny
whenever i warm up the car, and drive for the first 5-10 mins i don't go into fourth gear. BTW i have a 2k2 auto. is it because the tranny fluid still needs to do some warming?? cuz i keep staying on third gear. i don't think there is any way to resolve this. but how about improvements?? hmm... like mobil or redling ATF? and plus since i live in IL, its gettin reallie cold over here. and its taking a longer time to get my fourth gear!!!

When the ATF is thick and cold, the torque converter won't lock up. Synthetic ATF (Amsoil, Redline or Mobil 1) can help alleviate this some because it will flow better at cold temperatures. I wouldn't expect it to go away totally though.

Nissans have been doing this since the 1980's.
The ECU/TCU work together to control the transmission. If the engine water temp is not high enough, it will NOT shift into overdrive or TC lockup. Can't remember which one.
It has nothing to do with ATF viscosity or temp. Its all about emissions and quick warm up.
Best thing to do is start your car a few minutes before you leave for...... This way the engine has time to warm up. Also, avoid the highway until it is warm. The cold windchill will slow down the engine warmup which will exaggerate this issue.

I've noticed the tranny won't lock up until well after (sometimes 5 minutes after) the water temp. has reached normal when it is really cold out. This leads me to believe that water temp is not a factor. I didn't know there was a sensor in the tranny, but it doesn't surprise me.

On my dads Camry the tranny will not go into 4th gear after I start driving when the car has been standing still. I read somewhere that a car does this becasue the tranny oil is not up to running temperature and it will only shift when it warms up.

I don't think that it makes it rise faster in temperature but It should lubricate the tranny internals allowing them to handle extreme temp. better, less wear and tear and a little more power to the wheels. Like 1hp or 2hp.
