I'm not an expert on the Aisin Auto box in the 4runners, but I do have quite a bit of experience with similar slush boxen.
If you're having a problem with the tranny overheating, don't bother replacing the stock one, just replace it with a larger, more robust one. These universal tranny coolers are cheap and easy to maintain. This could be a sign that you've got some potential problems, but that's just something to keep in mind.
An example of an aftermarket cooler that'll most likely run circles around the factory one is:
~$50 after parts for:

(if you're a do it yourselfer)
or for $70 or so, you can get a kit from Draw-Tite at:

That's the idea, basically. Keep an eye out for other problems though. Check to make sure that your lines are in good shape, and that there are no kinks.
Let me know if you have more questions, I'm sure others will have great advice too.

If they just rebuilt the tranny and the AT light is on, The transmission is slipping. It might not be slipping enough for you to notice, but when it starts to slip the fluid gets really hot.
As for the tranny cooler, you shouldn't need one. I'm running my tranny with only the radiator trans cooler and it doesn't over heat. I'm also running 14psi on my motor and pulling a full sized car trailer with cars on them. I usually tow until my tank is empty and within the 4 or so hours of driving on the interstate my tranny still isn't overheating.
You would need to bring it back to them and tell them to fix the problem and not just install a bigger cooler! Now the bigger cooler might fix the light problem but will not fix the transmission. In the long run the tranny will go out again. You want them to fix the problem and not work around the problem.
