These transmissions use a sliding keyway to engage the gears that looks like this.
The shifter is on the end with the thing that looks like a pulley and it just pushes the keys into the gear you want.
This is why mower trans cant shift on the go, the keyways can easily engage 2 gears at the same time.
If you want to turn this into a gokart trans you would have to take every other gear out and grind the teeth off so the keys can pass through without catching 2 gears at the same time.
