I accidentally grinded 1st gear during a 2nd gear downshift when coming to a stop. Now, I usually never downshift into 1st unless the car is basically crawling, and I'm not sure why I did it this time, but I was going less than 10mph. SRM was on too. It's a new transmission with about 7k on it and this is the first time I ever grinded a gear with it. Should I be concerned about any long term effects that this may have caused on the synchro or gear? Doesn't 1st gear have triple-coned synchros or something like that?

It's been fine ever since. No popping out of gear or grinds. I just can't get the thought out of my head that I grinded 1st by accident. Appreciate any input.
