Just look on the TDR you will not find dead CP3's, if you do it would be from someone that is not running stock power.
GM did not dump them for Denso for no reason!!!
Another biggie I do hear some having high temps with their Allison's. I can tell you pulling 14% grades locked in 2nd for miles at temps in the 90's my trans has never been over the upper 170's. Pulling any grade in temps well over 100 the same can be said. My engine temps are kept well below 215 as the fan comes on and within a minute they are down. RAM has amazing cooling systems, I tow 33-35K with all temps in check in all conditions.
