Had a B&M shift kit installed (street strip) and was hoping that would give a shift on command option. (No more about JMod, didn't know when it was done). Anyway if I shift from 1 to 2 manually it stills winds out then shift somewhere about 4k. I was told to down shift from drive to second. This does shift on command with a healthy chirp of the tires. My question is whether doing this occasionally is OK for trans? Thanks . Yes I did search before posting this question..
