I am not too impressed with the late mopar trannies.
The trans in my srt300 croaked at 17k miles.
And I didnt even drive it hard. In fact I rarely drive it at all.
I have a 46re now in my legendary POS Dakota and I am doign the transgo tfod3 kit which makes the trans fully manual for my pleasure.
My biggest beef with any of these late model trannies is that the electronics suck. The governor control circuit in my dakota has been a problem since day 1. No more.
If I ever go to a different trans I'll just pull out my low rear gears and put in a 727 from cope. At least then I know I will never have a problem. Cope trannies are awesome, and I'll get a lot more power to the wheels without that overdrive housing.
