should FP gearboxes work in both forward and reverse?

Good morning Chief Delphi,

Last night we had mounted a 2012 KOP Fisher Price gearbox and motor on the side of our elevator. We wanted to use it to power down the bridge lowering rail. It went down just fine. However it stutters, for lack of a better term, coming back up. The motor appears to run for a second, stop, run, stop, etc. But only in reverse.

I wasn't sure if the gearboxes were meant to only go one way, or if we're having some other problem. The gearbox seems to me that it would spin fine in both directions, especially because of it's real-life application. Though, I guess it's possible 'power wheels' only go forward? Been years since I rode one.

I'm starting to think it's a programming issue, but I wanted to double check in this forum that there is no mechanical reason for our FP motor/gearbox to work fine in one direction and stutter along in the other.
