If it's like the Vette transaxle...they suck. They make any drivetrain excessively long, and lose much of the weight over the wheels benefit from actually doing a mid/transaxle install in the first place.

And apparently it takes a good few quid to make the Vette transaxle take power reliably. Not sure which aspect of it is weak though as they look pretty big but you always see the Vette guys complaining saying they are weak.
