I just replaced the transmission mounts on my 200q20v a few nights ago.
It's a pain, but clearly possible. Do the drivers side first. There's
plenty of access to get an end wrench on the tops of the bolts (17 mm
for the center one, 13 mm for the outer ones).

The heat shield on the passenger side has three screws (8 mm heads) 
holding it on. Two are easy to get at...one is hard. Also, getting a 
wrench on the tops of the bolts is more difficult. If you reach through 
a hole in the the inner fender, you can get the 17 mm bolt fine, and one 
of the 13 mm bolts too. The last one is a lot more difficult.

Alternatively, you could pull the catalytic converters off (good time to
check them for blockage I suppose) and the tranny mount job would be a
piece of cake.
