Bashing my new 3rd generation genny this morning and suddenly when pressing the trigger engine reves, pinion and spur gear rotate, but truck is not moving.
Spur and pinion gears are fine.
When truck is on the ground and putting a finger tip on the spur gear, I feel no restistance when moving truck forward and only little resistance when moving truck backwards.
Anyone experienced this before and what could be the reason ?
Could the transmission be broken ?

Any input appreciated, thanks in advance
