No tubing wrenches needed. 1/2 - 5/8 open end. If it was like mine you will have tee's off the pump on the pump side of the tee there is a jam nut loosen the nut first then the tee will remove easily, you will need to reuse the tee so be careful not to damage the o ring.
One other thing you might need to be prepared for is adding a ground wire. On my factory install it grounded from the battery to the pump body, which was metal and made a good ground, not the case for the ground lug on the new pump so a drill and a little wiring may be needed.
All in all simple job once the tranny fluid is all cleaned up.
