Just recently purchased a 2000 LC with 202k miles and it needs some work done to it. Whenever I start it, the A/T temp light comes on and it's really dim. But there are no issues with it shifting or wierd smells. It doesn't seem to be any real issues. There wasn't one when I test drove it a few days ago but the alternator was just replaced two days ago and since then it comes on. I also checked the atf level and it was really high on the dipstick.
 
Does the light go off then or stay on while you're driving it? Sounds like you should drain and refill transmission, especially if you don't have any service records pertaining to it.
 
i haven't driven it around just for fear of making anything worse but it stays on as its running. I will definetly have the fluids flushed and refilled.
 
if the light comes on with a cold engine and transmission i would suspect the sender. or a short in the wire leading to it.
 
So after driving it around the block a few times, the light goes out on it's own. No bad sounds and temp gauges are all good. Could be the send unit going bad but I will keep an eye on it.

Reviving a bit of an old post here..... Did you end up replacing the sending unit and fixing your problem? Running into a similar issue myself at the moment.

I didn’t end up doing anything about it. I haven’t noticed any issues or driveability issues. Temps stayed good, stay current on oil changes and changed out the fluids. I wouldn’t really worry about it unless you just don’t like the light coming on at startup.
