I upgraded after orientation a couple of days ago and the tractor I was assigned has a push button autoshift trans. Today I had to back 4 times, this truck will not creep, when I let my foot off the brake it doesn't move and when I hit the accelerator it lurches big time. There doesn't seem to be any in between with this truck.

Is this normal or do I just not have the right touch with it yet?

You have to learn how to work the gas pedal instead of the clutch. I do not have creep mode either. Slowly press the gas pedal until it starts moving. The weight of the load and angle of the ground will make a difference. It just takes practice. Sometimes it will still jump, quick breaks. Once moving the less stopping the better. It just takes practice. Good luck.

My trainer had a 2017 Pete automatic and that baby lurched when backing. My 2019 Kenworth not a problem at all backing. Really is just as smooth as a manual.

Hobo, it's an issue with some of those trucks. I'm guessing you're in an International. They had that problem, but so did some of the others. I'm guessing it depends on the brand of transmission in the truck.

You can manage it, but it takes a really light touch on the accelerator. It gets worse the sharper your angle is at your pivot point. Sometimes locking in your extra drive axle helps a little. The 2019 models seemed to have overcome the issue. Hang in there and eventually you'll get a newer truck that doesn't have that problem. In the meantime you can learn to deal with it by practicing a feather light touch on the pedal.

Yep, it's a 2017 International. Today I've been able to control it in a straight line but it still jerks like crazy when I'm bent. I guess it just takes practice, which I'm getting plenty of doing shuttle runs.

My 2019 cascadia.. oh boy. It either wont move at all, or takes off like a slingshot when backing. If on any kind of slant or grade it's even worse . Bucks. Jumps, etc. Irritating.

Yesterday I was going to my shipper , and they were doing construction work so I was the first in line. When it was our turn to go my Cascadia wouldn't move. I actually had to shut the truck off, and then restart it for the trans to shift. The construction workers all came over to see what the problem was. I didn't know, but it did move after restart. It happened bef

Before about a week ago at an intersection. But no one was behind me. She still has crazy backing speeds, sometimes she goes slowly and other times not at all unless I use the accelerator. But it's all good.

These transmissions require adequate air-pressure to function properly.

I am also familiar with the feature you mentioned...

If it happens again, put the switch in neutral for a second. Move it to Drive or Reverse. Should work. If not? Have the shop take a look.

Backing?

My experience is to get the truck moving first by finessing the throttle (pedal) then allow it to creep. For docks with a slight descending incline, once the crest is reached, I’ll place the trans in neutral allowing gravity to ease the trailer back to the dock.

It’s a learned skill and although it’s “wonky” at times, over time you’ll forget about the nuances of auto-shift.

That is interesting Susan, my 2019 does nothing of the sort. Maybe you need a software update of some sort. My 2015 FL had a tendency to do that, so when I got the new one, I figured they had sorted it out.

Wow.......I sure used the word sort enough times!!!
