Does this sound like a transmission issue?

Maintenance/Repairs

Hello, I’ve got 1999 Kia Sephia with ~130,000. Rebuilt the transmission at ~100,000.

Recently when I would shift it into drive, I would hear a loud noise steady noise, sort of like a muffled Harley running at a red light, the vehicle also vibrates a little. When I accelerate it gets a bit louder. This noise was never usual.

The second I put the car in neutral I can tell the transmission disengages and the sound is no longer made. It never happens in Neutral or Reverse. Is louder during acceleration but when I stop accelerating after 25 mph the car sounds like it normally did.

Also I revved the engine at neutral and it sound just fine.

What do you guys think?
