A/T Temp lights ?

A/T Temp lights came on while driving. I checked the A/T fluid level, and it seems fine. What could this mean?

It means your ATF is getting too hot......

The light should go out if you continue to drive on a straight or down hill road. So the tranny fluid can cool down.

I had the same problem and I got a transmission cooler and it solved the problem. My only problem is that I could only mount the tranny cooler above the skid plate. I wish I could have put it behind the front grill or somewhere else where its less vulnarable.
 
Aftermarket tranny coolers are cheap and easy to install.

If you're going up a steep hill with the OD on, that would cause the tranny to get hot too. Try turning the OD off.
 
The tranny cooler runs about $50-$100 bucks. It depends on how big or how many fins you want. I got the smaller one that fits under the skid plate. The only problem is that if the car is not moving, no air is flowing through it. In that case, a electric fan could help move are through the cooler when the vehicle is stuck in traffic or crawling up a hill with a heavy load. The tranny coolers can be bought just about any chain auto parts store and they are usually universal to most cars that have the room.
 
"Is it a DIY kind of thing, or is it hard to do?"

It's not that hard, you just tap into the tranny hose that runs from your radaitor back to the tranny and create another loop so that the new cooler is in between the radaitor exit tranny hose and the tranny. It is a DIY.

Might as well drain your tranny fluid too as it might be toast from all the heat. Don't put the fluid back in until you install the tranny cooler. This way when you fill it back up, run it and then add more, you have compensated for the extra capacity.

Some people take out the loop into the radaitor section and just run the tranny cooler, this might be helpful if your tranny cooler section on the radaitor might be plugged or leaking.

Good luck.

That's the easiest, and frequently the best way to do it.

The tranny cooler in the radiator isn't the best, and if the vehicle is running hot it could actually transfer heat to the ATF.
