What happens if you over rev first gear?
Over-revving can cause damage to your valve train by causing a valve to stay open for too long. This leads to valve float. Valve float occurs when a valve is stuck in between open and closed.
Why is my transmission revving?
This condition can also be caused by low transmission fluid, contamination due to lack of maintenance or water intrusion, or internal wear and tear on the transmission parts inside the transmission. A high revving engine is a typical sign that you have worn clutches or other parts inside the transmission going bad.
Why does my transmission rev up before shifting?
Shuddering
A shuddering transmission usually stems from issues with lack of holding by the clutches or bands due to wear or pressure issues. This could be caused by many things including dirty or low fluid, improper signals from the computer, an ill running engine, worn or damaged clutches, valve body issues and more.

Do high revs damage engines?
When you rev your engine, you place additional and unnecessary stress on your car and its engine.

What happens if you upshift too soon?
If you shift too early, you run the risk of lugging your engine, asking it to move your car forward at an unnaturally low RPM. For more details, and a side-by-side comparison of the fuel efficiency achieved in 2nd, 3rd, 4th and 5th gears at identical speeds on the same stretch of road, watch Fenske’s video below.
