I am looking for help with my jcb, it seems to have lost power, not from the engine, but the transmission, it will move both forward and reverse, but seems to lack the power to move withn any speed or torque, it feels like i am in 3rd or 4th gear, i can change gears and do feel the differnce in them, just don"t have the power it used to, oil level is good. is there a filter in the transmission/powertrain that could be restricting the flow, or something else that gives these symtoms? I have not noticed any wierd noises or anything. The setup i have is a 4 speed on the floor, forward and reverse on leftside of column, and handbrake on cab floor, left side.
 
I used to have a 3C 11 with what I think had the same problem. My problem was the pump on the right side of the motor. This pump's the fluid to the automatic part of the shuttle.

You should have a pressure gauge on the lower left side of the dash, one will be the temp and other is pressure, pressure should be aprox. 150 when operating properly.

If this sounds like your problem, let me know.
