[turbodaniel]

HELP! I just took possession of my 4500 it has a 6.4 engine 108 wheelbase with a custom body weighing approx 4000lbs
This truck is a absolute pig, absolutely no acceleration the tranny seems to not downshift when decelerating and in not the right gear when accelerating I have appt. at dealer next week , thought I would post hear for possible insight Thank you

 

[KKBB]

Just curious why you purchased it if it has no power and doesn't do what you want it to do as far as shifting goes?!?!

 

[Travelin Ram]

Is it new / are you the first owner?

Post a 0-60 video showing the tach and speedo.

that large of vehicles, weighs at least 7800 pounds U.S.
without anyone in it, nothing in it but a tankful of fuel.
Then you add the weight whatever type of bed you picked to sit on it.

I'm curious as to why you would buy a 4500 series with the 6.4? That's a beast of a truck that truly needs the Cummins engine.

I have not driven a truck with the 6.4 and Aisin AS66, but based on my experience with the AS69, I can see where it would feel lazy with a gasser. The ZF 8 speed works great with the 6.4, but I don't think it's even available in the 4500/5500??

DITTO x 100. RAM 4500 absolute monster work truck, Cummins, not a 6.4 gasser, IMHO...

Where are all the people that always say that gas is better than diesel? Seems like this guy isn’t happy with his hd gas truck

It's all about duty cycle, and expectations. Many utility companies, etc. that run bucket trucks or other heavy service bodies have gone to gassers to avoid DPF clogging and having to do manual regens, and all that good stuff. It's a tool to them and they don't expect "spritely" performance.

I have pulled a toy hauler with a 2015 pickup with 6.4 and 66RFE that went across the scales at 23,160 combined. Was it a barn burner? Nope, but it got the job done.

The Aisin is the potential wildcard, but I don't know if it could be substantially worse than the 66RFE. I have driven, not towed, my friend's '19 with the ZF and it was noticibly better than the RFE.

My '05 was a Cummins, my '19 was a Cummins, and my '24 will be another Cummins, so I have made my choice.

 

[Travelin Ram]

Yeah, back when I was buying fleet vehicles gas MDT were popular. Exactly the tool where GVWR was important and GCVWR was not.

Business buyers spec based on the calculator and don’t need or want a fast truck. Cost of operation was the first priority.

 

[NCRaineman]

Expecting a 4 ton work truck to be fast is your problem.

Man, I hope to actually hear the outcome of the OP's appointment with service, but I wonder if that is going to happen...
