Camaro SS '10 standard transmission bug

[FLK]

Anyone else noticed that the top speed is set too high on standard transmission? I've modified the one I have below but it's still set at around 280 mph on a new car. I've changed the units to km thinking it was not changing from kmh values but then it goes up to 530 kmh.

Its not a bug, its called "overdrive" what you see is the theorical top speed the car could achieved.
Here you can see that the ratio are correct: http://en.wikipedia.org/wiki/Tremec_TR-6060_transmission

Didn't know that, just it looked a bit odd to me being set that high but thanks for explaining.
