You said your T-5 is not mounted to the chassis?
Do you mean you do not have a transmission cross member? If not, you should put on in with the rubber isolators. You might consider moving the rear pads on your bellhousing back or eliminating them and use a trans mount. This may be be the problem. Pinion angle too. The rear pinion should be parallel to the trans pinion yoke. The rear pinion should be approx.5-7 degrees (facing down)as the rear end will torque up during accerleration thus being faily level when driving.
