The video was shot under the assumption that not everyone is as knowledgeable about their transmission. Sure most transmissions will shift automatically but constant improper use can damage your engine. Every transmission has limits and shifting too late, too often, can and will most likely damage your engine.

Its a valid concern. His engine is operating abnormally. I'd be very concerned if I were him.

The video strictly covers cars with automatic transmissions not manuals.

And what's wrong with that? Should you not upshift and damage your engine?

Not all cars are the same. The vast majority of engines have more power at the higher RPMs. Why your car loses power at higher RPMs is very strange. You should probably take it to a shop and have a mechanic take a look. You probably broke it or are going something wrong.

The video explains how to shift at higher RPMs for added performance compared to not shifting to at redline. Comparing the two options the former will shift with 30% more HP/torque compared to the latter.

This is should help!
