I've been looking at used Dodge cummins and find a good amount
of units available. It's seems that many are being traded at the
100-150K mark. Some a bit less miles.
They look to be nice units,and being told that the power train is
good for much more than 100k is there any real concerns on units
of this vintage? Any known gremlins in these? Thinking auto
I need a heavy duty, reliable
towing truck and have settled on the Dodge
cummins, just not which one.
Avoid the automatics. The engine torque in combination with high load toasts
the clutches. Even the standard clutch with the manual gear can be suspect
under severe load. A dual disk clutch would resolve the problem, but they
are grabby and harder to drive. The problem is exagerated with increased
power with either the power chips or later model engines. However, they are
still the best there is at the moment.
A good, but expensive, solution to this would be to replace the
transmission with an Allison, like a lot of medium duty trucks use.
That would put an end to most of your transmission worries, but it would
knock your wallet for a loop.
If you do find an Allison transmission in a Dodge Ram then it's been put
there by a custom truck shop. The only light duty trucks I'm aware of
that have them out of the factory are GM. Where you find them in other
manufacturers' products is in medium duty trucks.
I work the ramp for Southwest Airlines, and a lot of our provisioning
trucks are Ford F-650 truck bodies with Cummins engines and Allison
If you want to install an Allison transmission in your Ram, I'm sure a
good truck shop could do it for you, but expect to pay a fat stack of
cash. The other side of that equasion is that with a Cummins engine and
an Allison transmission you'd have the heart of a medium duty truck in
your Ram pickup.
Sounds good to me! but yeah, talk about costly. Why doesnt Ford or Dodge use
the Alison from the factory? I believe GM own's Alison, (or part of them)
so that might be why they dont do it. but still a sale is a sale, I wouldnt
think Alison would care who they sell them to.
You hit the nail on the head. GM owns Allison. GM wants to keep
factory installed Allison transmissions available only on GM
manufactured light trucks so they can use them as a selling point. But
they'll happily sell them for aftermarket customizers to use, and even
provide adapter kits for mounting on other manufacturers' engines,
Cummins in particular.
Or ... he could just go ahead and factor in the cost of a new tranny up
front. All auto transmissions, (Ford, Dodge, Chevy) at some point are
going to start having problems if they are used long term under stress
... even if they are well maintained.
For me, with Dallas traffic getting worse by the day, the auto tranny
is worth the potential of future $$$ in repairs down the road.
I say that now ... I'll report back when I drop my first 3-5k on a new
