It's not your engine or transmission, but you have the ride height set too low. The plank under the car is scraping over the circuit, and when the plank wear reaches 1mm you get a drag penalty (red). So, choose a higher ride height, or stiffen up your springs. Arnold

It sounds like your car is bottoming out, you'll probably need to adjust the ride-height of the car, ie raise it...

This is happening because the plank (a 10mm wooden board stuck to the bottom of your chassis) is rubbing the ground due to the extensive downforce created by your high speeds. Once you have rubbed more than 1mm off of it, there will be a substantial reduction in power, creating loss of speeds. Depending on how severely you are rubbing it (like, is it solid yellow, or just flickering), this 1mm reduction could happen fairly quickly. There are several ways to adjust this; the most obvious is to raise both your front and rear "ride heights" (remebering to keep your rear heigher than your front) until the plank no longer rubs down too much. However, raising your ride heights also reduces the amount of downforce traction you will have, so there are things called "packers", which can offset the amount of ride height vs. bottoming out. I can't remember which works most effectively, but there are a couple of setup guides out there that explain it pretty well, and even though the manual looks like it doesn't do a very good job at first, really read it thoroughly, and it might shed some light.
