Hi my name is***** will be glad to try to help. What is your machine serial number?

Expert:  Dan replied 1 year ago.

First check the oil level and condition for burnt smell, discoloration and the filter internally for fine metal/debris and suction screen for the same that would indicate an internal failure. If okay, test for power in and out of the shift controller in all gear positions and then to the shift solenoids going to the transmission. If there is power in but not out to the solenoids it means a faulty shift controller which is a common wear item when the contacts inside fail over time. If that is okay but you have metal/ debris in the filter and oil as well as suction screen it indicates an internal mechanical failure. If aluminum it is a converter failure if friction material it will indicate failed clutch packs. If steel material it can mean a failed transmission charge pump. A pressure test with test gauges to test the pressures at the valve body will be necessary to confirm if you have low pressure in all speeds indicating a faulty charge pump. Let me know
