Synchrotech-Torco MTF showed up and I filled the transmission with it. Shifting still feels crunchy, but not in a bad way anymore. Third gear needs to be coaxed when shifting at speed, but I think that’s not really a bad thing.
Just to make sure that I have it listed here, my break in procedure for the transmission was:
100 miles with 10w-30
500 miles with Honda MTF
and now Torco MTF
