A hydrostatic transmission (HST) exists any time a hydraulic pump is connected to and dedied to one or more hydraulic motors.

In this type of transmission, the rotational motion of the engine operates a hydrostatic pump on the driving side. The pump converts rotational motion into fluid flow. Then, with a hydrostatic motor loed on the driven side, the fluid flow is converted back into rotational motion.

And the transmission seal kit prevents fluid from slipping past the input shaft.

The transmission seal that is most commonly replaced to prevent leakage is the tail shaft seal. This seals the driveshaft where it attaches to the output shaft of the transmission. It is attached at this point with the use of splines. As the vehicle moves, the driveshaft moves in and out as bumps are encountered.
