Check the tranny fluid. if it's dark brown it and the filter should be changed. they can do this at most oil change places. but it could be as simple as some loose sensor wires. hope this helps.
don't forget to add 50% water and coolant to your resevoir tank of your coolant when it's low.

Car is idleing to high,engine coolant sensor is reading to low, also transaxle sensor temp reads to low. what is the proble?

If the car is idling high I'd start by looking for a vacuum leak. I usually start by looking at the line from the brake booster that runs to the back of your intake. I have seen the metal connection degrade and/or work itself disconnected.

If you have not replaced the coolant temp sensor on this vehicle I would do so now. There were numerous reported issues with the originals in these cars and they have been reported to cause a whole heap of what some would see as unrelated issues. They usually run about 14 bucks and are fairly easy to replace.

Engine Coolant Light blinks constantly.

you put transmission fluid in your radiator? You should have antifreeze in your radiator. You could have a bad thermostat that's causing the car to over heat. Does your temp gauge read a high temperature?

Temp Gauge Creeps Up

I would take it in and have then do a block test to be sure you don't have a head gasket issue, Does the coolant get low after a few days or so. This could be a sign.
Also sometimes its hard to get all the air out when you drain the coolant and fill up. Be sure the coolant bottle is up to the ok line..
And if everthing checks out ok then maybe your ready for a water pump. The fan blades on them tend to wear down then they dont pump water too good.
Lastley your radiator could be clogged.
Best bet is to go to a shop and pay the 50 bucks give or take and let them tell you whats wrong

Car stalls intermittantly without warning

Try pulling the engine coolant temp sensor, They often crack not sure why but the ceramic tip cracks makes the car hard to start, the car's idle may race while shifting gears, and often smokes. The sensor is on the right side of the engine when looking at it on the head. Easy to change and get too
