Was cutting hay today and my trans light started flashing and none of my power shift gears will shift. You can kill the tractor and move it to whatever gear 1-4 on the power shift lever start it up and it will be in that gear but if you try and switch gears while tractor is running nothing. The trans light is flashing constantly. Any help appreciated.

Sounds like a possible bad control module, check by using the following method....if wiring harness, switches and solenoids check out I would be going after the control module in side console. 

NOTE; TO TEST POWER SHIFT HARNESS PRESSURE SWITCHES, SOLENOIDS TEMPERATURE SENDER AND GROUNDS DISCONNECT CONNECTOR “J” WHICH IS LOCATED IN BOTTOM FRONT OF SIDE CONSOLE.

OHM BETWEEN THE FOLLOWING PINS TO TEST PRESSURE SWITCHES AND SWITCH CIRCUITS.

#1 V-F, #2 X-W, #3 J-H, #4 L-K THESE SHOULD ALL READ "CLOSED"

OHM BETWEEN GROUND / CHASSIS AND THE FOLLOWING PINS TO TEST SOLENOIDS*

#1 N TO GRD, #2 P TO GRD, #3 S TO GRD, #4 T TO GRD

*SOLENOID SHOULD MEASURE 7-8 OHM BY ITSELF SO WITH SOLENOID IN CIRCUIT IT WILL BE A BIT LOWER 6.5 TO 7.5 TYPICAL GOOD READING.

TEMPERATURE SENDER TO GROUND AT 70-80- DEGREES SHOULD BE 550-470 OHM”S

PIN M TO GRD GROUND TO CONTROL MODULE

PIN G TO GRD
