In writing, I don't know of any - Maybe Mark will step up here and let you know - he was on Ford's Tranny Team.
But unless people have trashed the 5R110 with a tuner that can not be programmed - like the Bully Dog, they are pretty much bulletproof up to 500HP+. Verified by the many, many users here in FTE.
I have never seen a comparison done by an independent company or a "torture test" for durability.
I have seen many people run their engines up to 450 hp and not have issues (and I watch a dozen forums and have done so over the course of years). I think that is about the limit though. Most folks at 500 hp + also had their transmissions beefed up. That being said, I have seen torqshifts fail due to tunes (as Bud said) and stock ones fail due to poor maintenance, wrong fluid, etc. Additionally, you add horsepower, you will add wear-and-tear ... nothing is free! BTW - I don't have any supporting data for what just said - just my opinion from watching and discussing over this (and other) forum.
Even though Mark didn't bite, what you asked certainly is a question that the smart buyer would be trying to answer since the Allison has benefitted from a TON of hype (deserved or not)!
The best answer (IMO) is to talk to dealership techs that you trust (I know of 3-4 here that would qualify as expert witnesses!).
I know that Mark is a pretty smart guy. Perhaps he should come to my dealership to help me figure out the cause of a no-crank no-start issue on a 2011 F-450 with low mileage that appears to have been through several hands before getting towed to me. I have had this truck in one of my bays completely gutted for about three weeks now with what appears to be a network short/shutdown that not even our field service rep or higher up can figure out. I would love to see/hear Mark's input on this particular concern. Sorry for the highjack.
But yeah, I pretty much get the impression that Mark is the kind of guy that perceives "mine is bigger/better than yours" type threads are childish, and rightfully so.

I have very little experience with this type of problem. The one time I can remember working on one was a GM product*. I was able to find the problem by disconnecting each module one at a time until the network came back up. The module had an internal problem that was shutting down the network.
*After leaving Ford in 2007 I worked for a supplier on a GM program. Specifically the 2012 Corvette ZR1.

Been there, done that already. The curveball on this particular truck in question is that I have already gotten as far as determining that there is a HS CAN- short in multiple areas, areas in which harnesses that COULD BE the source of the problem have already been replaced, only to be no further ahead. They (meaning the higher ups) have instructed me to replace the PCM, which I didn't think was going to resolve a thing, and sure enough when it arrived on Friday, it didn't. So as it stands, I am becoming more interested in what the outcome of this vehicle is going to be.
Well i have no interest in a conversation of whos is better. That little part of my post "i have heard that there better than allisions" wasnt even the important part. All i was asking was for supporting info to learn more about these transmissions. So for you who thought that was what i was trying to do, it is not. Thanks.

Bismic, thank you for your insight. I appericate it.
