6220 STOP Low transmission pressure

[khufstedler]

Hey, When I unplug the pressure sensor just above the filter on the rear of the transmission the light goes out, and I can view which gear I am in and other info & messages. When I plug it back in the STOP light keeps flashing and I can only read the fixed message about changing filters, and checking fluid level because the transmission pressure is low. Everything seems to be working fine.....1500 hours, new filters, new oil, and new lines from the big filter by the rear tire. What else could be wrong?

Sounds like the filter restriction sensor is bad. Actually sensor on filter on front of transmission is on same circuit, so it could be either one. If unhooking rear one makes warning go away, I would replace that one first. What kind of oil are you using in trans? I had to change oil in one tractor to get this message from coming back. It drove me crazy.
