In total there are four mounts.
Front transmission mount - looking down from the front of the car is located on the front of the tran, slightly left of the airbox location.
Rear transmission mount - this one is located on the rear of the trans, in the same relative location as the front mount, only on the back instead of the front. This mount is wedged between the power steering rack and the subframe. Overall the toughest to swap due to it'* sandwiching.
Torque axis mount - This mount is located on the end of the motor at the passenger side.
Dog bone mount - This mount is located on the back side of the transmission tail shaft on the passenger side of the car and is the easiest mount to swap because it does not carry any of the motor/trans weight.
