Drive line problem
 

I have a 2003 mini cooper S. I have replaced the rear main seal, timing belt, water pump, changed oil in super charger, replaced all hoses and put in new CV axles. Upon completion I drove it out of shop and proceeded about 100 feet and lost propulsion. Engine runs good, clutch works fine, transmission shifts ok, wheels do not turn. On jack stands the the wheels turn the CV shafts into the differencial. Has anyone experienced any thing similar to this or does anyone have any idea as to what problem is?
