Hello,
The codes:
P0730: Problem in Shift Control System
P0780: Mechanical Problem in Hydraulic Control System of Shift Solenoid Valve A and A/T Clutch Pressure Control Solenoid Valves A and B. Or Problem in Hydraulic Control System
These could get triggered due to faulty shift solenoids or pressure control solenoids inside the transmission.
So, it could require the replacement of those components.
I have attached the basic diagnostics steps below for P0730 and P0780. Follow these steps and that can help you determine the issue.
Let me know of any questions.
Thank you.
