I have always ran suncoast trans in my dodges however when I crapped the trans in my 08 and went looking for a tans, there was a local guy with an ats 68re, who did have some trouble, he had 1 of the first and kept breaking it as his horsepower increased. however once the ats unit got to its race configuration he hasn't had any trouble. I opted for the full built ats , so far it is holding well. not a ton of miles as the truck is only driven every once in a while. when it is driven it is beat on and has been holding for a year.
