Check to see if the backup alarm is working indicating you are getting power to solenoids on transmission control valve.If it tries to move, check for a snap ring broken in the modulator valve holding the valve open. If there is no movement at all and the alarm doesn't work, most likely the time delay relay (the tall relay at fuse and relay panel) has failed.If all of that checks out okay I recommend having your pressures tested and confirmed whether or not they check out with an oem specifications for your model and serial number service book. I hope you find this information helpful. Reply back with the results of these checks if any further help is needed. It is a pleasure to help anyway I can.

Is that modulator valve the forward reverse solenoid on top of the transmition? and were is that snap ring that could be broken?
Mechanic: Dan, Technician replied 1 year ago

The modulator valve is in the control valve of the transmission. You would inspect the complete valve for any damage or debris as well as any potential problems with your spools or other components such as a failed snap ring.

Hi Dan, I have a 140 WB Komatsu backhoe I would like to know the hydraulic pressures. I have been getting around 2000 PSI
Mechanic: Dan, Technician replied 1 year ago
You will need to open up a new request for your Komatsu on the website since it is unrelated to your case question.
