  1. hey cihtech i have a 94 Case IH 5220 trans light comes on while using loader and steering. Checked pressures for steering circuit and remote circuit. Adjusted pressures so there was a 300 psi difference. Problem still exist. Ohmed out pressure switches on side of trans with tractor off. All checked the same. When light is flashing tractor still drives and loader functions work but your stuck in the powershift gear you were in when the light came on. Any ideas??? From what ive read you seem to be the master at these transmissions

      What is your email address? I have a bulletin that will help you pin down whats going on. 

      Just forward of any one of the 4 pressure switches is a test port for that gear, get a gauge in there and see what kind of regulated pressure you have in shift manifold.

      The pressure switches open on rising pressure, while ohming them out tells us they are closed. I like to test them one at a time to make sure they open. Starting with tractor in said gear and meter in switch start engine switch should open, repeat with the following switches. Order of switches from top to bottom is 3-1-2-4, just make sure you have it in the gear select you want to test when you start engine. Alternately you can remove them and test them using an air pressure regulator. 

      Good luck.......
