E-Series spec - it uses a transmission mounted drum, which sounds superior to a driveshaft based parking brake
Same effect. I called it "Driveshaft" because it keeps the Driveshaft from turning and not the Rear Brakes themselves. Yes, it's Transmission Mounted. If you jack one rear wheel off the ground, even with that Shaft Brake set, it can roll down off the jack because the wheel still on the ground can roll. The wheel you jacked up will turn in the opposite direction from the one rolling.
Setting that Brake is equivalent to putting it in Park. No better.
But Wait!!! (I feel like and infomercial...) There's More!!! That brake has its own little supply of ATF, and when the seal leaks, it's usually the one on the TRANSMISSION side, not the Driveshaft side. That means you don't see the leak, the Brake runs dry, and its internal bearings fail.
