Vibration @ 4000rpm

[BYRDPE]

Hello folks,
Every since I did my AOD to T-5 swap I have been having vibration at around 4000rpm.
I only does it when in gear.It's not really vibrating through the shifter but it's like you can feel it throughout the whole car.
Any ideas??
Thanks for the replies.

tires might need to be balanced if the whole car is vibrateing.

he said it only does it when its in gear...hmm

vibrations are almost always caused by the driveshaft. Did you use that aod driveshaft with that stupid balancer on it???

Try unbolting the driveshaft and rotating it over a notch and see if that changes the nature of your vibration. I'll put my money on the driveshaft.
