Stalling a truck

Are you having a problem stalling out your truck?

 

Putting it in too high of a gear when taking off. Not downshifting quick enough going up a hill. Basically too high of a gear for where you are at.

Running out of diesel or def will also stall one out.

 

The PNDB on a Freightliner going bad or losing connection will shut it down quick too.

 

Dumping the left hoof at a high rate of speed.

 

Taking off in too high gear, trying to take off with park brakes applied, trying to take off with frozen brakes, steep hill/muddy conditions (see "too high gear" mentioned previously), lugging engine down too low, sick engine, running out of fuel/fuel restriction, restricted air intake, aftertreatment system plugged up, engine protection shutdown, loss of power or ground to ECM, broken ignition switch wiring.......


Etc etc

 

and if it's an old truck with Jakes that don't auto shut off at slow speeds, that'll do it too.

 

Driver error... if you driven stick in a car it’s very similar. When I first started driving truck my main reason for stalling was when I came to a stop without downshifting all the way and leaving the range selector up when taking off. It’ll likely be a situation that you’ll be in until you pick up downshifting in the lower gears.

 

Forgetting to flip the range selector down when a light goes red seems to be the most common I see.

Especially if you are in the habit of staring out in 3rd. Still driver error if you kill the engine before notice and deal with it.

 

Not quite a stall... One time I had the old Cat 3406B spinning backwards because I left the jakes on too long.

Couldn’t drive the truck at all. No steering, no oil pressure and can’t find gears.

Wasn’t til I shut the truck off and restarted then everything worked normally.
