An interference motor is when the pistons can hit the valves. Either from a broken timing belt/chain or if the motor is spun too fast and the valve springs cannot pull the valves back fast enough.
Some motors have either reliefs cut into the pistons or the combustion chamber is large enough to allow for clearance. It has nothing to do with tranny or options, but rather engine design.
If we have an interference motor and you spun it too fast, you can get minor valve/piston damage. But it sounds like you are going to be fine.
