Screech when driving

Toyota Tacoma 2004  120000 miles
I own a Tacoma TRD 2004 manual 4x4 and the problem is the following: when driving over 30 mph, an annoying screech appears and increases with time. It only disappears when gearing and pressing the accelerator. When driving in third gear, I noticed that, if I speed the car up, the screech goes off, but the speedometer suddenly drops and the vehicle loses speed. Can someone help me or explain to me which the problem might be? Thank you.

Do you hear the screeching noise when you start the truck too?
