I suspect the short term effect isn't catastrophic, as under-geared robots get pushed backwards quite often. But, I suspect that having this happen continuously, as might happen in a mismatched motor system, might cause something to overheat and fail.
Anyone know?

We did have some issues running a CIM FP Andymark Shifter (any series) over a repeated use of time. The FP finally gave out after 4 tournaments though.
