Low houred 931B Cat working fine one day,next day won't move.No fwd. or reverse,doesn't sound like it's trying.Loader hyd. still work fine.Any ideas?Thanks.
 
if its a power shift may be clogged transmission screen or filter---if not check pressures at transmission test ports
 
(quoted from post at 11:53:36 12/16/15) Changed filter.Didn't check screen.Where are the test ports?
Maybe dirt in check valves on transmission or torque converter , I had a D7E several years ago and it was a small piece of dirt maybe from the Oil I put in transmission . This check valve was on the transmission and difficult to reach .

I have had that happen to my 931, but not from one day to the next however. The trans fluid became a little too low due to a slow leak around the driveshaft seal. If you pull the trans dipstick before starting the level is supposed to be far above the mark and after starting the level goes way down. Once I brought the oil level to full while running everything worked fine. I had previously dismissed the possibility of it being low on oil because I checked it before starting. Most of the time these transmissions are quite bullet proof.
