I just did the same job on my 2.5L I4 w/AX-5 tranny. The I6 may be a little different.
The driver's side motor mount was torn clean in half, I didn't notice, since the weight of the motor kept it together, till lifting it out and top part of the rubber section of the mount fell out of the mount altogether.
Straight forward on side motor mounts. For the Passenger Side mount I had to pull the alternator off its mounts (but not the wiring) to move it aside enough to pound out the thru bolt on that mount. Make sure to unbolt the mount from the frame first, then jack the motor up enough that it actually lifts the mount from the frame a bit, that way your sure there is no weight on the mount and the thru bolt will come out with just a little tapping.
I had a little more trouble with the trans mount, I have 2WD BTW. It probably would have been easier to support the trans and drop the crossmember. I tried jacking the trans up, it will only go about an 1.5" before it hits the trans tunnel, if you jack to much you could damage the shifter on top of the trans. I ended up removing the plate under the trans that connects to the mount, and pulling it out with the mount and swapping mounts on the plate and putting the plate back in. Only 3 bolts for the plate and it does take a little bit of tilting and rocking to work it in and out between the trans and crossmember, but it can be done fairly easy.
Might be just easier to support the trans with the jack and drop the crossmember for a few minutes to swap mount, provided the crossmember unbolts without too much trouble.
