New (to me) ZR1 with Trans Problem?

[csx4350]

OK, I changed the trans fluid to the Castrol TWS and the noise is still there. It was actually over filled, when I pulled the fill plug lube came pouring out. I made a few observations on the test drive. Understand that due to too many firefights my hearing isn't great any more.

It whines in neutral, but stops when I push in the clutch.

It whines on acceleration, but gets much quieter (or possibly even stops) on deceleration.

It whines in first through third, but appears to go away (or at least gets much quieter) in fourth and above. I was working really hard trying to keep the road and exhaust noise down listening for it but couldn't hear it.

i have same pbl with mine (1990 17000 miles on it)
whines in neutral but stop when i push the clutch and in first through third
i guessed it was normal 'cause i have a black tag ZF
and i read that it was "normal"

changed trans fluid recently with amsoil and gears passed without any pbl except that noise
