No, No, No!! I'm taking about leaving the transmission in the tunnel, and reinstalling the engine w/ the trans in the tunnel. NOT attached to the engine like pictured above.
Doh! Well, I've never put the engine back in the car with the trans still in the tunnel. Doesn't seem like the easiest undertaking. Like SSeater said, it probably isn't fun to do, but can be done with great care and finesse!
