I have a problem going into fifth gear. If I go in at 80km or less no grind, If I go in at 80km or higher grinds all the time. I tried using Gm syncromesh with fm and no help at all. After using this fluid sometimes its hard to get into first. Whats going on.

Also just for my info all B series trasmissions will work with all B series motors right/wrong( I am pretty sure they do) and are all clutches and flywhells interchangeable.
