What is the seal between the transmission and driveshaft?

What is a Slip Yoke Seal? The slip yoke is the part of your driveshaft that connects the driveshaft to the output shaft on your transfer case or transmission. The slip yoke seal is the seal that allows that yoke to move in and out while still keeping the transmission or transfer case fluid sealed inside.
