You will have to pull the transmission and flywheel the rear main seal is on the back of the engine, and it will be a 1 piece seal that goes over the crank shaft and drives into a houseing that holds the seal in place. need to lube crank with grease or oil before installing seal. You will need a seal driver. You can not get to it by removeing the oil pan. You can pull the engine out and leave the transmission in and get to it that way. IT IS EASER TO REMOVE THE TRANS.
