Explain this old school wisdom I get told by some oldtimers.

Old school ??? Old Timers ? Theres a flip side to that coin. Young Wipper snappers, Green Horns. Wet behind the ears. Still learning, i like that.

 

Yes keep listening to lies at the coffee counter at the truck stops When I started I had several guys tell me they put it in Georgia overdrive (knocking it out of gear)going down mountains .So like a D.A. I did it going down Saluda mountain on I 26 at NC and SC line around 3am one night I only had 20,000lbs on and didn’t think it was ever going to slow down held on for dear life praying the wheels didn’t come off that 1987 KW.That’s when I stopped believing lying as@ truck drivers

 

Well, I did both, a tug test upon the initial hook, and a short roll pulling the Johnny bar, to make sure it's hooked and to see what kind of brakes I had, if any. A walk around after hooking up should see a "high hook".

 

I still use "19th" gear

 

I want to know what the OP means by old timer and old truck.

 

Almost every automated manual is capable of it AND gets it back in gear. Lol and here I thought all that was illegal.

 

Technically they disengage the clutch and don’t kick into neutral.

 

Omg, that's awesome, the best way to use it in a manual is to just push the clutch pedal in...sure it'll ruin the clutch forks, but at least you won't have to fuss with the stick gliding around in neutral position tryna to get it back into gear.
