✅ Revisable €249

P0717 The signal from component (sensor) Y3/8n1 is not available
P0718 Component (sensor) Y3/8n1 is defective
P0720 Output speed sensor circuit malfunction
P2200 The signal from component (sensor) Y3/8n2 is not available
P2201 Component (sensor) Y3/8n2 is defective
P2204 The signal from component (sensor) Y3/8n1 is not available
P2205 Component (sensor) Y3/8n1 is defective
P2767 The signal from component (sensor) Y3/8n2 is not available
P2768 Component (sensor) Y3/8n2 is defective

👉 Please note:These malfunctions can also be caused by deviations in the magnetic sensor rings(e.g. damage or iron filings).

🟡 Potentially revisable €299

P0721 Transmission output speed signal is implausible, compared to wheel RPM
P0722 Output speed sensor – no signal
P0723 Output speed sensor is defective
P0894 Transmission component slipping
P2206 The signal from component (sensor) Y3/8n3 is not available
P2207 The value of component Y3/8n3 is implausible
P2550 Component (sensor) Y3/8n3 is defective
P0705 Component Y3/8s1 selection range sensor is defective

➡️ These fault codes often appear as soon as the software detects deviant signals from the speed sensors.
➡️ Do these codes appear togetherwith the errors from the first table?
First have the TCU revised, clear codes and re-read.

Specific fault code

P2806 Component (sensor) Y3/8s1 is not learned

For this fault:

Diagnosis shows no shift positions
TCU must be re-learned
If the fault persists → shift position sensor defective(we replace this during revision)

🔴 Not revisable

P0606 ECU/TCU processor error
P2716 Pressure control solenoid – electrical
P2783 Clutch actuator temperature too high

➡️ At high temperature + limp home mode, this indicates wear or damage to the lock-up clutch.
➡️ Check magnets in the oil pan for iron filings.
➡️ If there are many filings, it is recommended to:

replace the entire gearbox + torque converter
flush the oil cooler (or replace if it contains a thermostat)

Solenoid-related fault codes

Possible defective solenoid valves or other transmission malfunctions:

P0748 Pressure control solenoid “A” – electrical
P0778 Pressure control solenoid “B” – electrical
P0798 Pressure control solenoid “C” – electrical
P2716 Pressure control solenoid “D” – electrical
P2725 Pressure control solenoid “E” – electrical
P2734 Pressure control solenoid “F” – electrical
P2759 Torque converter lockup clutch control solenoid
P2810 Pressure control solenoid “G” – electrical

➡️ The above fault codes may indicate defective solenoid valves, but the problem could also lie elsewhere.
