3 years later update: Guys, it's either not leaking or not leaking enough to drip on the driveway
This rear main seal installation method is not the proper way to install the seal. Factory service manual for 3.5l Pathfinder states the lower oil pan has to be unbolted in addition to the transmission. The intent of the video is to help those who have either assumed its not difficult to install without dropping the pan, or those of us who did not read all instructions from factory service manual before removing old seal. Hopefully this can save your bacon if dropping the pan is not an option for you.
Basically, sand down less than 1mm of rubber material from the under side of the gasket. sand down enough to eliminate the radiused edge of the molded rubber on the underside until you now have a defined corner. on the back side of the gasket, sand in a chamfer or taper for the corner bits. When installing, use a metal punch (ideally with dulled edges in order to not cut rubber) to assist with pushing and squeezing in the new gasket. If gasket does not fit after multiple attempts, consider removing a tiny bit more material from gasket. Use extra rtv around corners.
Main project was to replace a bad transmission while using PTO at work. Before installing the new transmission I thought I'd go ahead and replace the slightly leaky rear main seal since the Haynes manual never mentioned dropping the upper oil pan. After breaking the first replacement seal with brute force, I came up with this hack job to get another replacement installed. The outcome was that I was able to reinstall my transmission and drive my rig back to work on my next scheduled day. There is a slight oil leak like before, however it's very slight.
