There's no doubt that the 4.7L's torque curve is narrow and "peaky". Maybe
the 45RFE, which was designed in coordination with this engine, is a better
choice?? I have alays been a manual transmissiuon kinda guy, so that's why I
have what I do. I mean, if I wa satisfied with an automatic, I would have a
Dakota R/T, but I just couldn't give up my standard shift intuition. I have
the 3.92track-lok rear as well, and it goes down the road very nicely. From
the little that I have "gotten on" this truck, I can clearly tell that they
are not that fast. Just not enough power to really do anything with. Now,
for what I use it for, it does just fine, but for somebody looking for a
real performance-oriented vehicle, I'd tell them to look elsewhere. I keep
seeing people post about breaking the tires loose on dry pavement, and I
can't see that appening wiht my truck, no matter how hard I push it. I mean
I can catch rubber on the 1-2, 2-3, 3-4, and I guess if you really tried,
the 4-5 shift. but as far as just punching it and the tires start spinning,
I don't feel like the truck's got that in it. Maybe if I was to side-step
the clutch at about 400 in second, it would go nuts, but I'm not going to do
that! Sorry for the ramble, I don't know where I was going with that.

I enjoy shifting, so I got the 5-speed manual on my '00 and have not
regretted it for a minute.
Ron's right about the auto having it's own computer. There is actually
twice as much code for the tranny as there is for the entire engine. My
brother is an engineer at chrysler and he said this in a recent mail
(AN=Dakota DN=Durango WJ=Grand Cherokee):
"545RFE is our new rear-wheel drive auto trans, I'm responsible for the
logic. It launched in the 99 WJ, and is now on the AN and DN, and the
RAM(DR) next year. It's matched up to the new generation engines 4.7, 3.7,
5.7. It's a great enhancement for these engines cause of the "peaky and
narrow" torque curves really benefit from the low end torque multiplication
of the torque converter."
I happen to enjoy the torque multiplication of 3rd gear and a 3.92 LSD!
