I would recommend replacing them with a pair of Vex VersaPlanetaries, and using the JVN Mechanical Design Calculator to figure out a ratio that will allow your robot to climb well. I bet you can climb nearly 4 times as fast as this setup is geared for without much of a problem depending on the diameter of your winch and weight of your robot.
This is why we post stuff like this, so it isn't bad news, on the contrary bad news would be having our gearboxes blow up in our first match of our first competition.

We thought we had done the math on these motors and gearboxes, but have yet to test them.

Thank you all for the input. I'll have the team do some research and once we decide on something we'll post an update.
