drive noise in my new t-5?

[90dpscoupe]

As i said in previous post, my 1st t-5 was whining like crazy, until it finally broke a cluster shaft, now i have a totally rebuit t-5 (not the same core) is working great, but on deceleration i hear a slight noise , nothing like my old t-5, but is this normal? i have the stock shifter in, about to install a ripper.
