Sure. Pick THOSE directions. Stay calm. You need to shift way slower than you think you have to. He can only tell you things from the passenger seat. You have to get the feel of them. You know how to drive. So don't forget how just because you get the privilege of doing more of the work involved. Driving a truck is a solitary occupation. You have to do it. That means that you have to master yourself while you master the truck. Your audience can encourage you, it can chastise you, it can give you advice (Good, bad and ugly), but only you can do it. And, in case you have any doubts, you CAN do it. And also: He knows what he has and is willing to give it a go. You are in a #### good position: Make it happen.
Guessing 6spd straight truck? Easy peasy. When i first drove in 2004 thats what i had. Just got to listen to the engine see where the tachometer tops out for each gear without going to high.
Dude, you won't like my answer, it is really the best one. Stop worrying about stupid crap, just do it.
My go to advice is this.... Your in a truck. People expect you to be slow and in the way. Dont disappoint them.
No offense to those on here trying to help you, but you're not going to learn this online. You've advised the o/o (your employer) of your situation. My advice is get off this site for a day or two, let him train you, then come back in a couple days and let us all know how easy it ended up being after all.
My dad taught me how to drive a semi. When I was learning shifting and I'd get all bent out of shape and mad at myself he told me "you can't be mad for expecting to know how to do something you've never done before." Which is true. Everybody starts somewhere. You'll grind gears, you'll be in wrong gears, you'll lug the engine or you'll be rappin it out. Big s&$@. You'll get it. You got good advice on here and the willingness to learn I don't see the problem. And you were upfront with your employer. It'd be a lot worse if you said "hell yes I could drive a toaster if it had wheels." Then couldn't get it out of the parking lot. Slow and steady wins the race for sure. You'll be alright.
