Having issues going into 3rd and 5th gear on my Hydro B16 tranny. Grinds pretty hard going into third at anything above 3k, does the same above 4k in 5th gear. Already running GM Synchromesh, just changed it about 200 miles ago and didn't seem like it really did anything. My question is, is there anything else I can do to help this thing get into gear a little better? Just for the next month or so. I'll be pulling the tranny at the end of summer and freshening it up. Any suggestions, lets hear em. Thanks.
