My Dino shifts “pretty good” cold or hot but I drive and shift it with great respect and try make deliberate shifts with full clutch action. I can see that second gear, shifting up or down needs to be done with care and skill and not too fast. I never try to rush it. I always make sure when taking off in first gear, that the shifter if fully down in its gate. I have no idea what gear oil is in my sump. I’d love to know what you’re using in your Dinos with the pros and cons of what you’ve experimented with and your experiences.
