2020 Peterbilt 389 Heavy Haul, Day cab, Extended cab.

[@waltlovegren5937]

Why 3:90 ratio in my opinion they should be at least 4:11 ratio for heavy hauling

[@larrylovegren3254]

now I know where you hide

[@chrisdidomizio4958]

When you order a truck with a Cummins, you can get an RPM graph from them where it shows the powerband. 3.90 is at the bottom, 4.11 is optimal and 4.30’s is at the top end. @65 MPH 3.90 is 1524RPM 4.11 is 1599RPM 4.30 is 1676RPM Peak torque is at 1700RPM for a 565/2050 X15.

very nice truck. i'd love to run something strong like this to run my 4 axle conestoga hauling 75k lbs of coils. vs my 400 hp 12.7 freightliner that is struggling with it

[@EricBretl]

what is the GW and axile spacing

[@fireguy0020]

why do we not see the autoshift transmissions in the heavy haul trucks? love your videos

[@bryan70546]

the autos cant handle the torque output I belive

[@waltlovegren5937]

Because they would suck ass in a heavy haul application.

[@stephenroberts4895]

Manual transmissions are considerably cheaper (up front) than automated and Allison's. It's not that they can't handle the job, it's just because so many operators look at what they can save up front without looking at long term savings/potential benefits.

I want be truck driver please help me how starting?

[@sohailbundah7227]

What is the def tank ?

[@mikewhipkey6863]

Sohail Bundah it stands for "Diesel exhaust fluid" after the 2007 model year all diesels sold in the USA are required to have a "Diesel particulate filter" to filter pollutants from the exhaust and store them until it reaches a certain amount then it uses the DEF to burn up the stuff it captured... That's a quick and unprofessional statement... The "DEF" is basically an Assinine attempt by the Government to reduce "pollution" but in reality it just makes things more difficult for people that make a living in trucking... pretty much like what the Government does to everything it touches..
