2009 Nissan Armada ENGINE AND ENGINE COOLING,POWER TRAIN

MY DAD AND I GOT INTO THE TRUCK AND HE ALMOST SLIPPED AND FELL ON SOME TYPE OF LIQUID. WE PULLED OFF AND REALIZED SOMETHING WAS WRONG WITH THE CAR IT WAS GOING VERY SLOW AND THE ENGINE SOUNDED AS THOUGH THE ENGINE WAS RACING EVEN THOUGH WE WERE GOING LESS THAN 10 MILES. WE PULLED OVER AND CONTACTED AAA WHO TOWED THE TRUCK AND THE TOW GUY SAID THE ANTIFREEZE/COOLANT HAD LEAKED OUT WHEN THE TRANSMISSION HOSE BUSTED AND LEAKED OUT ALL FLUID. I'M TRYING TO FIGURE OUT WHY MY 2009 NISSAN ARMADA SE TRANSMISSION IS ACTING UP. *TR
