Yes, you can swap them with the tranny in the vehicle. You just simply use a big prybar, and on the pass side push in the servo cover and there is an internal ring that you can use a flat blade screwdriver or a pick to remove. Once the ring is removed, remove the servo and change it out. You might have to cut the o-ring to get the assy. out, but the kit comes with a new one. Just reinstall and use the prybar to push it in far enough to get the clip back in its groove. Takes 20-30min first time around.
