There are two types of shuttle,in the mid eighties JCB changed from using Borg Warner shuttle box to ZF,badged JCB,the BW shuttle had a cable operated forward/reverse lever and the ZF was electric F/R,a short lever stork on the left of steering column,if you got the ZF there is one spin on filter on the left side of the box and one suction strainer under a plate near the filter,if you got the BW shuttle there is no external filter but there is a pickup strainer in the little sump pan on the bottom,the pan has to be removed to service it,there is an o"ring on the pipe of the strainer if its gone hard it could draw air,the most common cause of the fluid coming from the filler of the BW shuttle is an inline check valve on the box,there is a pipe that goes from A to B on the box,in the middle there is a piece of hexagon bar about 3/4 inches,inside that bar is a ball and spring,the ball can jam or the spring break and that can causes the fluid to come out the filler,it is best to take off the whole pipe than try to take the valve part from it to inspect it,the valve comes apart,I have never known the ZF to throw the oil out so i can"t make any suggestions about that except to clean the strainer and change the filter,in both cases have a look at the lines that goes and comes from the cooler,see that they did not get a knock and are kinked and blocking the fluid flow,as was said in the other post the fluid level is checked with the engine on low idle. Good luck AJ
