I’m driving a 2018 cascadia right now and it’s a thing of beauty. Such an easy truck to learn on and lots of nice features that make it a babe to drive. XD

You need to release an updated version of this for the new cascadia

My company has disabled manual mode for some insane reason. I’ve been driving a D12 for 5 years that had manual mode and I loved it on mountains. For steep downgrades I would typically put it in 9th or 10th gear in manual mode and use the engine brakes and it would pretty much maintain the desired speed without using the service brake. In this video it talked about controlling descent speed by engaging engine brake and then setting cruise control to desired speed but I seem to remember the cruise control not working with the engine brake on. I’ll probably have to quit this job over this.

Awesome video! It's the only one that helped me find exactly what I was searching for. However, I find that the (P) in the Volvo's is much more efficient and affective, especially when empty.

I drive a 2015 Crashcadia with a 505 hp 1750 ft-lb engine. My problem with Eco mode is that when I bought the truck with 473, 000 miles on it the engine oil pressure when coasting was lower than any of the seven DD15 equipt trucks I had driven before. After getting the oil pump O-rings replaced in February the oil pressure is reading pretty much what I got at 320, 000 miles in the last truck I drove as a company driver. If I could change anything about the truck from a standpoint of drivetrain I'd like an override button for the coast mode in Eco mode.

One of the best auto shift Transmissions I've used so far

[el-hplj]

its not horrible if its paired with a powerful motor. eco mode shifts way to low rpm to keep heavy loads moving. got to switch to manual in a hilly road situation or this trans will keep shifting up and down for no reason

[chrishubbs]

My work has blocked out performance mode. It won’t go into that mode at all. Any way to bypass so I can get it other than using a computer? I find accelerating into the freeways very slow. Sometimes I’m trying to merge into traffic that’s doing 60-70 mph and I can only get to 30-40 mph. I find it dangerous. A few more mph would be great.

Very interesting great engineering and great presentation

I don't know if it is the way Schneider programed the transmission, but if I turn on the engine brake with the cruise control on the transmission downshifts to 10th tach goes to 23 to 2400, my tractor is equipped with a tag axel so the drives start to chatter skid, this is a violent reaction to the engine brake being turned on. The drive tires only lasted 68680 miles. This tractor is a nightmare to bob tail on wet roads. I have been driving trucks since 1975, first automated transmission, gotta say it is a steep learning curve, but I still would rather have a clutch.

[marquisio]

What form of engine brake is used?? ..constant throttle valve or exhasut brake?

[Danarchist]

I think its pretty good but is there a way to change the default mode to Perform? It switches back to eco at the most inopportune times.

[thomaskirkpatrick]

This video is all well and good, but it seems that every company truck I've driven has the manual and performance mode, locked out. This pretty much assures over revving the engine going down a decent hill.

[banurigopalreddy]

creep mode is like crawler gear system from Volvo Trucks

[jpugh]

Locked in ecomode tbese are trash absolutely dangerous with bad road conditions as you cant hold gear its always hunting for 12th or trying to go to coast gear, this trans never seems to do what you want it to trying to use engine brake down hills and it keeps kicking to coast i told the company these arnt safe but theyre to concerned about fuel milage

[frankmlchaelglasscock]

Any good truck driver should do that with a manual

[Unknown_Ooh]

Here at Detroit we believe in not fixing anything and would rather you buy an entire new transmission

[olivergunn]

UK truck driver here, funny seeing the exact same gear selector as on mercedes trucks, although they are shit trucks, Volvo and Scania are much better

Presentation is better then the actual experience of driving one, typical bullshit hype to sell this piece of garbage

[antor.j.medrano]

As always piece of shit, drove one it sucks. manuals better!
