do new and old trucks shift the same?

No two trucks shift the same. At least for me, even with identical fleet trucks, I have to get a feel for every truck I drive.
Now that said newer trucks should be smoother as there is less wear in the drivetrain.

 

Newer trucks are a dream to shift compared to old .
I don't miss trying to shift my 85 kw Coe with cable shift in sub zero temps ...needed a pry bar to shift it lol

 

Mine's REAL easy to shift. I just step on the fat pedal, twist the RH stalk forward (or reverse) slightly, and step on the skinny pedal.

 

Yes.

They all shift the same.

 

No.

Just grind it till you find it. But not in my truck, I'd hurt you.

 

No. My last company job I drove a 2017 Mack and it was "temperamental" in the shifting department.

I bought a 2012 Volvo and rides better and shifts better with almost a million miles.

No two brands shift the same and no two trucks shift the same.

 

Depends on how beat the transmission is. New/reman transmission shift pattern should be a lot tighter than a worn out transmission.

 

I have been in 6 trucks in the last 9 months now. None of them have been really in any way similar. Hell, even then 2 automatics I have been in didn't drive the same and they were both freightliners from the same year with similar mileage.
