Humming/ vibrating noise starting at 20mph-60mph. Stops when I lift my foot from gas pedals.
Gets very loud occasionally. Someone said torque converter, then someone said it wasn’t. Any ideas please!

Vibrations during acceleration are mostly caused by an issue with the drivetrain and the first thing you should suspect is unbalanced driveshafts, CV joints, or prop shaft depending on vehicle type. Could also be unbalanced tires showing more when acceleration, but driveshafts are far more common.
Unfortunately, it can be quite tricky to test them and the best way is to have a car lift and try to see where the noise is coming from.
