Coasting out of gear relinquishes an important portion of control. Only thing left is brakes and you may need acceleration which ain't there.

yep I have actually saved my own butt before when I was almost stopped in traffic, saw the car behind me was not going to stop in time, floored it and got onto the shoulder more than once. One time, the car behind me stopped about 6 inches before hitting the car that had been in front of me! Had I already been coasting in neutral there was no way I would have avoided that. now, I come to a stop, clutch in and in gear, until I see at least the car or two behind me stop, then I will drop it in neutral to wait for the light to change or traffic to move.

 

This is the main reason I don't coast to a stop in neutral.

 

id like to investigate the trans shaft splines.

 

99% chance it is synchros. If it were the clutch dragging, binding ,etc it would be happening in all gears.

It is kind of odd that it is 5/6 because typically the lower gear synchros get more of the beating.

 

When my clutch was dragging, crappy ebay clutch from po starting to drop a spring, it was way worse in some gears than others. To the point it could have veen written off as normal operation in other gears.

 

I do this at very low speeds, about 50 feet from the stop sign, and the shifter smoothly glides into neutral…no popping.
