Will a Ford Contour or other transmission fit a 2002 Jaguar X Type 3.0?

While there is an external similarity, the ultimate answer is no. Jaguar used a 5-speed automatic made specifically for their car, while the Contour trans is a 4-speed. Since the transmissions are computer controlled, the computer in the Jag wouldn't know how to deal with the Contour, or any other, transmission. Your best bet is to try to find a good Jag trans in a wrecking yard.
