I only have one Transformer, the Optimus Prime truck but the motor and mount seem to be the same as all the ZipZaps SE's that I have and you should be able to swap the motor on your Bumblebee.

I would try a motor swap on my Optimus Prime just to make sure but it is highly modified and the motor is buried deep inside and it would be a major effort to get to it.

The only problem I can foresee is the Bumblebee has a square base motor (I think) and the motors in the booster kits have round bases so you might have to fool with it some to get it positioned right and/or use the motor clip that comes in the kit. I think the clip on the Bumblebee has a long grounding tail that the clip in the kit may not have. I've done a lot of similar motor swaps on ZipZaps SE's so it should work. My only caution is to be gentle. These things are not "Built Ford Tough".
