Hi my name is***** will be glad to try to help Do you just have forward speeds and no reverse or is there a problem in forward speeds as well? Check the oil and filter condition for metal/debris indicating an internal mechanical problem. If okay then test power in and out of the shift controller in each gear position and to the solenoids for a possible failed controller. If there is power there and no movement check the resistance of the solenoids to verify they are all in line with resistance values. If so the next step is to have the pressures tested and look further into an internal problem. Let me know

I have switched wires it will go into reverse it seems there is no power to the reverse side?
Mechanic: Dan, Technician replied 1 year ago

Thanks for the info... So if it will engage reverse powering the solenoid separately test the outputs of the shifter in each speed. If no power out in reverse you likely have a bad shifter.... Contacts are known to wear out.

No there is no power out of the shifter? What about for forward?

Customer reply replied 1 year ago
forward I have power and if I switch wires I have power for reverse
Mechanic: Dan, Technician replied 1 year ago

If you are testing right out of the shifter it means the shifter has failed
