To diagnose such a thing overthe internet is a bit silly. Look to see if the car can't be moved to D and pushed out and then loaded onto a flatbed, or pull the driveshaft and get it towed to a place that can look at it. The 4 speed box is known for being very though.
The SLS is a fluid filled system with various hoses, pumps and seals. Standing for long periods not only does the fluid degrade but it could possibly be a hydroscopic fluid aswell and that means water in the system and that is full on failure.
