Wierd grinding noise from the Banebot transmissions

[andrew_4_life]

We were extremely tight on schedule when we were building the robot and didn't get to test it till the day we shipped it. When we powered up our robot, there were loud noises comming from transmissions or wheels when we drove it. When we drove it straight forward(Note:We proped it up on boxes so there was no load on the wheels) the wheels weren't driving properly. One was starting slower than the other. I don't think that it was a calibration problem, but rather the gears in the 2 motor adapter was grinding against the cylinder part of the BB transmissions. What does everyone else think? And if it really is the gears grinding on the transmission, is it possible to just let it run and grind away the rest? (It takes a LONG time to take apart and we won't have time at the competition.)
