A built Chrysler vs. the Allison.
The Allison is only as weak as the clutches that are in it. The convertors are a bit soft, but much much better than a 47r. I wish I would've taken a picture of them side by side. The smallest shaft in the 1000 series is bigger than the biggest shaft in the 47r I replaced.
Another point, the allison has 5 speeds, 6 if you work some valve body magic.
You shouldn't have to worry about the shafts, sprags, sun shells and other hard parts in a transmission. You won't have to worry about any hard parts in the allison.
Plus, it's a very smart transmission. The grade braking software is unparalleled. Not to mention it's great potential for those wanting to add PTO accessories or integrate it into a work/commercial type vehicle.
I believe it's a great alternative to a built chrysler transmission, which IMO won't last half as long as a built Allison.
Thanks,
