yet another trans question+ rookie error

First the rookie error - when I changed the oil at the onset of winter, the old filter gasket stuck on the engine, I didn't notice and spun the new one on. What I learned is that gasket on gasket does not a seal make and pumped a gallon of fresh oil all over the place. Luckily I noticed very quickly.

So I have run the engine with the new damper plate (and another new gallon of lube oil). It all works. The chatter I used to get at low idle in neutral has vanished. The shaft turns both directions and makes lovely thrust.

When I engage fwd drive there is now a rather boisterous noise from the velvet drive ( fresh trans fluid) until engine speed reaches 13-1400. The noise is present in reverse also, but less so and goes away at lower rpm.

A trusted source blames the engine for delivering a not nice harmonic, hence the noise.

Thoughts?

Could it also be from improper alignment which I have not done yet? Or from a crap shaft zinc on the outside?

Thanks in advance

Abnormal noise is generally bad. Diagnosing a noise without a description or hearing it is impossible. For instance a deep thumping knocking sound can be a cutlass bearing. Rattling is generally something that has come loose and only makes noise at a certain vibration. Whatever it is you need to track it down.

I hear this at home too. Usually we are in bed and just before my wife drifts off to sleep she says "Oh, by the way honey, the car is making a funny noise."

Try a wood dowel of an approate length and hold in in your fist just below the the first finger and put the other end on different parts of the engine, trans assembly and listen for the noise.
