Transmission Error Codes
General error code format:
* P (Powertrain) — Indicates a powertrain error
*X — Indicates a specific control module (eg ECM, TCM)
*Y — Indicates a specific type of error
* Z — Indicates a specific error code
Examples:
* P0700 — General transmission error
* P0715 — Input shaft speed sensor — malfunction
* P0740 — Hydraulic circuit — electrical fault
Common error codes and their descriptions:
* P0700 — General Transmission Error: Indicates a general malfunction in the transmission system.
* P0715 — Input Shaft Speed Sensor — Malfunction: The input shaft speed sensor is faulty or not calibrated.
* P0720 — Output Shaft Speed Sensor Malfunction: The output shaft speed sensor is faulty or not calibrated.
* P0730 — Incorrect Gear Ratio: The gear ratio does not match the programmed values.
* P0740 — Hydraulic circuit — electrical fault: There is an electrical fault in the transmission hydraulic circuit.
* P0750 — Shift Solenoid A — Electrical Fault: Shift Solenoid A has an electrical fault.
* P0760 — Shift Solenoid B — Electrical Fault: Shift Solenoid B has an electrical fault.
* P0770 — Shift Solenoid C — Electrical Fault: Shift Solenoid C has an electrical fault.
* P0780 — Shift Solenoid Malfunction: There is a malfunction in one or more shift solenoids.
* P0790 — Transmission Pressure — Malfunction: Transmission pressure is too high or too low.
Note: Error codes may vary depending on the make and model of your vehicle. Please refer to your specific vehicle’s repair manual for exact information.
