I was driving back with r mode and accidentally switched to D. What's going to happen Thanks?

Answer 1

Assuming that you were driving a car with an automatic transmission and that you accidentally switched from R (reverse) to D (drive) while the car was moving forward, it is likely that nothing significant will happen.

The car may briefly slow down as the transmission shifts gears, but this should not cause any damage to the transmission or the engine. Modern automatic transmissions are designed to handle quick and smooth transitions between gears, and switching from reverse to drive while the car is moving is generally not a cause for concern.

However, it is always a good idea to be careful when operating a vehicle and to pay attention to the gear selector to avoid accidentally shifting into the wrong gear. If you notice any unusual noises or behavior from the car after switching gears, you should have it checked by a qualified mechanic to ensure that everything is functioning properly.

Answer 2

the automatic transmission will shift through all of the forwarding based on speed.
