Shifting a new trans

So the first manual I drove on a regular basis was a 18 speed hauling gravel trains with almost 1 mill on the trans. I just started with a new company hauling baffle-less tanker in a 13 with about half a mill on the trans. Both these trucks had their learning curves but I feel I picked em up pretty quick and I became really comfortable with the trans in both and could shift quickly and not grind gears. Today my truck broke down and they put me in a few veteran guys trucks with less than 200k on the trans and jeez what a world of difference. I mean i've heard of 'tight' transmissions but I hold the shifter at the face of the gear but instead of a gradual slowing click till the gear falls in you kind feel it slow down then it zips right past the hole, but if I hold it any harder im just grinding it. Im still really green but the tolerance on a newer trans is otherworldly, I can get the job done but I honestly like driving a truck thats worn in rather than these newer ones. Couldnt imagine a brand new one. Im posting a link just to kinda show where im at. This was me in the train at around 2 months, I dont have anymore recent videos. https://youtube.com/shorts/Ov9n4lNApPg?si=uY2OoKWUiaL4kJfZ

 

Id be interested in driving a brand new trans to see if maybe its just the way these other guys broke theirs in. I try to have a pretty light hand and not just slam it in while a few other guys dont care much. One of the guys I work with said if you have the overhead re-tuned every 100k or so it helps tremendously and if done right it will almost suck you into gear. I know that that hasnt been done on any of our trucks.

 

Could be. Im pretty green so I couldnt say. Just something one of the senior guys brought up.
