. Ticket the Truck.!! :eek:)

This is something we'll have to come to grips with sooner or later as self-drivers keep getting more autonomous but that's a discussion for a different vehicle entirely :Big Laugh:

I had similar issues with my 2014 Express with 5.7 Hemi 6-speed until I change the Tow/Haul so it defaults to Tow/Haul mode (think Sport mode). The shift points are so much better. Drives like a "normal" truck now. Don't notice any difference in fuel economy.

The overdrive on my 2017 Tradesman is slow to change gears. When going up a hill, it doesn't start to gear down until going about 5 mph under the set speed. Then when it does gear down, it is going so slows that the RPMs jump to 4500 and it roars into action and by the time you reach the top of the hill, you are at least 5 mph over the set speed ...
I would not expect to see much difference between your 2014 and 2017. Both should jump over 4,000 when downshifting for a hill. Both should go a few under before the downshift, and end up a few over during the climb.

While a bit of throttle before the hill or as it slows and using tow haul are common work arounds, my question would be what did your last truck do?

Everything on my tradesman is slow to react. Stop at a stop sign and when you get ready to go, you press down on the accelerator and nothing happens, so you press a little more the RPM goes way up and you roar away down the road.

Turn on the fan on the heater or AC and nothing happens until a long delay
What engine and gears does it have? What is it's history?

If there were an issue with the thermostat I could see the truck taking longer to heat up, and that could impact drivability and performance.

Lots of posts on slow throttle, most being answered with get a tune or aftermarket device. Need to compare to similar make/model option as first step.

I've seen a few posts on slow throttles with the diesel and doing a throttle calibration (Turn your key to the run position, wait for all the lights and chimes to go off. Slowly depress the gas pedal all the way to the floor, and then slowly release it all the way up. Repeat two more times. Turn the key back off. Then start the truck.).

These trucks are programmed to chug and lug, and drone at the lowest RPM possible. While that may yield an additional.0001 MPG, it’s a miserable driving experience. While most people are staring at their phones while behind the wheel, there are still a few true Drivers left.

I do my own shifting; that’s why I’m such a fan of the Slap Stick. Paddles would serve the same purpose.

Your truck can't see the terrain ahead
It is sort of like you being blind folded & not knowing what is ahead

When the Cruise Control is On, our Rams when driving on a gradual up hill grade seem to down shift at the correct shift point & it is hardly noticeable

Unfortunately, if the uphill grade is 5 or 6 %, whatever the sensor is that determines speed, is off & does not downshift until the speed is 6 or 7 MPH below the set speed & when it down shifts, you realize how much power you have under the hood when it downshifts

I have ridden in a Ford pickup on that same road as above & noticed that its speed sensor catches the point it should down shift at 2 or 3 MPH below the set Cruise Control speed

Not for cruise it won't, and it won't fix a shifting issues. I really get tired of all the Pedal Commander bullhockey. Yes, it makes the pedal more touchy, but doesn't fix anything else.
You're right,nothing helps a Ram downshift easier and quicker.It's a dodge...lol.But mine aint doing what the op truck is doing now.
