The Jaguar dealer replaced the transmission and related parts in the car as it was un-drivable. After re-assembly, the car would make clunking sounds when turning tight turns and over bumps and dips. This became more noticeable over time, until the dealer wanted to replaced most of the suspension. It turns out that the transmission sub-frame is bolted through the floor pan to spot-welded nuts. The technician broke these nuts loose during re-installing the frame member (perhaps by over-torquing). The drivetrain would then shift during the tight turns and over bumps making a loud clunking in the unibody.
