Worn out gears in a transmission will cause the transmission to slip out of gear. The gear may be war only on one side, causing the transmission to work properly. At times.
if it smokes when you first start it, or sometimes if it has a tic tic in the top end intill it warms up
mine was acting up too. took me forever to find it. it was the range sensor.

it really could be a number of things, but more than likely its either the idle air control valve that is sticking, or your transmission fluid is dirty. When your transmission fluid is dirty or has particles in it, the car will idle rough and seem to want to turn off, once it warms up and the gunk glogging the transmission filter is stirred up, the car will seem to run fine. If you let the car cool and that gunk re-settles, it will do it again.
Because you don't have enough the transmission fluid in the system.
yes
Try to replace the oil filter if the transmission is not engaging when it's cold.
It is because of how fast the car idles. When you start the car it is idling high and when the engine warms up it slows the idle to about 650 RPMs and the torque converter in your transmission is slipping and not moving you forward at that low an RPM. what causes the torque converter to slip? CAn it be a sensor problem?
Your floats might be stuck.
Check the transmission fluid level (no you cant check it like oil level you need to have it on and in gear (make sure the wheels are blocked and the emergency break is on)). You may want to also check to see if the rubber transmission mount is sagging.
I would check the transmission fluid level.
be careful while radiator cap is off!! remove radiator cap, start engine, watch for flow of water as the engine warms. temp gauge is a goog indicator.
