JD 2155 Will not move

Hello All,
I am working on a JD 2155 that will only move when it is low reverse. The tractor has an 8 speed hi/lo trans with shuttle shift. I do not think that main clutch is out because it will work good in low (gears 1-4) reverse. but when i move the shuttle shift to forword the tractor tries to move but doesn't or it hardly moves. When i put the trans on the high side the tractor will not move in forward or reverse. First thing i checked was all the linkages in the shuttle shift and they seem to be tight and in good working condition. Second thing i checked was the fluid level in the trans and the was ok also. the hydraulics on the tractor (brakes, steering, and 3 point) seem to work very well also with no "chatter" What would i look for or do next to locate and fix my problem. Thank you very much.
 
You need to check your clutch pressures in your Hi-Lo unit.Sounds like you might have a problem in the Hi side.Also check pressures on the shuttle.Your problem lies in one of the two units.
 
Just to ensure we are on the same page. The tractor has the reverser option and has only 8 forward and four reverse speeds. No high/low shifter on the dash labeled with a rabbit/turtle giving 16 speeds.
Clutch pack apply pressure is something to check.Along with general trans pressure and even the pto pressure.
Any history on this tractor?
 
if the oil is milkey you got water in it they dont want to work the shuttle shift mine i changed the filters (yes 2 of them )and the screen in there also fresh oil and it was fine.
