Did freightliner intentionally set out to make a crappy automatic transmission?

So, this is actually a setting. In the newer (really new like late 2017 model years) it's a toggle switch, lower right down by the cup holders, you can set it to 3, 5, or 7 over before the jake kicks on. It's called cruise override. CC OVRD i think it says on the switch)

If you don't have the switch, it's a parameter that can be changed on the computer.

 

Once you understand how it works you don't need a special switch or to change the computer settings.
If I am starting to go downhill I bump the cruise speed down 3-4 mph to hold me at the speed I want to be at. Simple.

 

Suffice to say this is not as simple as a 2 speed Power glide in a 1963 Chevy. Different parameters and operational uses according to the application. Time would be well spent not only studying the operators manual, but also more detailed instructions probably available online.
To answer the OP. It isn't Freightliners fault the owner of the vehicle (Prime) decided to opt for parameters matching the entry level skills of the drivers they hire, serious degrading the potential of the unit.

 

I’m sitting here waiting to get a door to load, trying to enjoy the A/C and my truck keeps revving up on its own. It idles around 600 but will rev and maintain 1150-1200 rpm.

It’s a 2018 Cascadia, no idea what’s going on. I tried restarting, switching through the gears (D,N,R) and nothing seems to help.

Any ideas?

 

It’s trying to do a parked regen. You need to let it do this or you’re going to have problems later. This happens if you idle a lot or run around light a lot (rarely work the engine hard for very long) but mostly excessive idle is the cause for requiring parked regens

 

If it's auto it made for steering wheel holding with two hands, or a person with a handicap of some sort.
If your not either of those you don't need to like it. Find a job with a manual truck.

 

These sorts of comments are getting old and tired. But carry on if this somehow helps you get through your day. SMH

 

Ok, this thing doesn’t have an APU so it does idle a lot.

 

Idling and new DPF system trucks do not go well together. The maintenance and fuel and hassles costs over 4 years will exceed the cost of a new APU
