I don't know what you are fishing for here but to my knowledge edge tuners have not fried a tranny yet.
Some possible causes to tranny failure.
1. Internal mechanical failure. A. Valve body.
B. Clutch packs.
C. Pumps.
2. Oversized tires without regearing.
You start to ask a lot out of your drive line with the extra added mass of wheels/tires and starting and stopping. Even with regearing it still adds demand to the drive line.
3. Used vehicle=Not knowing if the tranny has been overused and abused.
Just a general observation, however there seem to be some of these trucks(04-06) that seem to be having failures at low mileages. I have been seeing more 06's than other years and 3/4's of all of them have never had a programmer.
So I don't know what more to tell you other than its probably not the programmer.
