Some gear boxes have electronics to prevent engagement if it is over-revved. Some don't.
The automatic EK4 is an example of an earlier generation car that had such a 'failsafe' mechanism heh heh.... The TCM prevents the gears from downshifting in the event that the engine loads (RPM) will exceed the parameters deemed safe as programmed from factory, even if the gearstick has been shifted as such. Tried and tested many many times along the NS highway and on track; at high engine and car speeds when you think you can downshift to get abit more grunt and you shift the gearstick accordingly from D4 down to D3, the gear does not change until your RPMs have dropped to a range where when the gear DOES change it will rev up to a point that is WITHIN the rev-limit of the car.

Fantastic! You'd need to be a complete dumbo to be able to thrash the gearbox that way! (which admittedly I became one eventually muahahaha....)
