What do you mean by going out? Blown completely? It's generally pretty hard to completely toast a tranny while its in limp mode, but I'm sure its doable if you try hard enough.
Each time you limp it you wear it a little more. Eventually you wont be able to accelerate 0-60 in less than 15 seconds without limping it. I might take off all the chips except for one, and run it on a lower power setting until you get some tranny work done.
