If you are using the CATIA Kinematics to simulate, check the Gear joint to make sure it's between the correct parts.

I think I understand now - you want to simulate "shifting gears" to a different speed ratio - correct?

CATIA doesn't do that. CATIA only simulates single 1 DOF mechanisms.

You have to make 2 mechanisms. A mechanism with the gears for the first speed, and another mechanism for the second speed. And then simulate them one-at-a-time.
