I agree. Nothing is perfect out there.
We have a 2001 3500 Dodge 5.9CTD/48RE and with only 78k miles on it, its on the 3rd transmission. One warranty and one on our dime. Its cursed.
Rebuilt a many GM 4L60E transmissions also. I don't see any reason to use them in a 1/2 Ton truck that is going to be towing. The large gear splits and weak internals are its problem.
But at least for GM a transmission swap to a better unit is easy. The 4L80E fits in the same space as the 4L60E and is a whole different animal and tuning for it is even easier.
