Your JCB will have a Borg Warner shuttle box,The fluid is checked with the engine running on low idle,with the engine stopped secure the machine and get a second person in the seat,go under the machine,get the other person to move the forward/reverse lever you will see the cable moving the F/R lever on the shuttle,check to see that the lever on the valve is moving into the dedent in both directions,ie there are three holes in the lever one to hold the lever in forward,one neutral and reverse, get the person to press the clutch pedal,you will see a plate that moves and push the forward/reverse valve in,on the end of the valve is a 1/4 bolt 7/16 head size,there should be .010" clearance between the head of the bolt and the plate that pushes it,if not loosen the locknut and set it at the .010",what that valve does is when you select forward/reverse fluid under pressure squeeses the clutch pack together causing it to drive,when the pedal is pressed it lets the fluid escape and the clutch disengages,check that the valve returns to the full out position,it is spring loaded to return but it can stick,that adjustment is the only adjustment on the shuttle,the most likely thing to be wrong if the valve adjustment is correct is that what is called the belelville spring is broken inside the forward clutch pack,the shuttle will have to be removed to replace it,the Borg Warner shuttle is very similar to the one fitted to the Case 580 machines up to 89, go to the link below you will see a parts list for the Case shuttle,item #9 is where the cable connects to the valve on the first page,item 49 on page 2 is the belelville spring it is a concave spring.hope the adjustment get you out of trouble.
