Found Hydraulic leak...How difficult to fix?
 

It is leaking from the seal around the input shaft right after the fiber driveshaft joint.

How difficult is it to replace this seal? Any "How To" videos or other info around?

There is some good info on this link

Pull the Drive Shaft and Coupler to expose the Input Shaft. You can try & pull the Seal or you can remove the Charge Pump to get at the seal better. You will need IH-394847-R91------>921-3032 Seal. Once the new seal is installed, reverse your steps.

NOTE: IF.........you pull the Charge Pump, pay attention to the "flat spot" on the side of the charge pump housing, and the orientation (RH or LH side). Install the same way it came off.
