Do you mean into the engine? If so it depends on how little; a quart is too much for a small engine. There wouldn't be any immediate damage but change the oil before running the car again.
internal transmission parts may stick depending on how much oil it was
Don't drive it, but have it towed to a reputable garage that can flush the transmission. Driving it with the oil may cause serious damage to the transmission.
In a small amount (a few ounces), probably not. A larger amount may effect water pump seals.
Yes, you could severely damage a transmission by shifting into reverse while moving forward. But the odds of the transmission actually going into reverse are not good because there are safety mechanisms in place to prevent it from happening.
Yes , it does.
Yes, it can.
It is possible that no damage will occur by accidentally filing a petrol motorcycle with diesel. The motorcycle make emit a lot of smoke as a result of doing this.
Accidently ? - If not very much, it'll probably just burn off without doing any damage. - But be careful in future, cars are not tolerant of most 'accidents'.
Possible transmission damage due to the overheating.Possible transmission damage due to the overheating.
If the engine will run you could drive it, but I would advise against it. The diesel may damage the O2 sensors and catalytic converter. Drain the tank and then fill it up with fresh gasoline. No real damage will be done with the small amount of diesel left.
Do not drive the car. Have it taken to a transmission specialist who will drain, flush, and replace the fluid. Most motor oil is too thick, and not compatible with the operation of the transmission. It could cause severe damage within a very short time.
No a bad convrter can not damage your transmission however it will make your vehicale run rough
