This summary uses the existing diagnostic information shown in full below.
This code means there's a problem with the car's computer that controls a special pump that helps move the transmission fluid. It's like a helper pump that isn't working right.
The P27E6 code indicates that the voltage in the circuit controlling the electric or auxiliary transmission fluid pump is higher than expected.
The P27E6 code is triggered when the powertrain control module (PCM) detects a high voltage condition in the circuit of the electric or auxiliary transmission fluid pump control valve. This could be due to a short circuit, a faulty control valve, or a malfunctioning PCM.
• Check engine light is on
• Transmission may not shift properly
• Unusual noises from the transmission
• Faulty transmission fluid pump control valve
• Short circuit in the wiring
• Malfunctioning powertrain control module (PCM)
PCM: Powertrain Control Module
OBD-II: On-Board Diagnostics II
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for damage or corrosion.
• Test the transmission fluid pump control valve for proper operation.
• Repair or replace damaged wiring or connectors.
• Replace the faulty transmission fluid pump control valve.
• Reprogram or replace the PCM if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Ford F-150
• Chevrolet Silverado
• Toyota Camry
• Regular maintenance of the transmission system
• Inspect wiring and connectors periodically
• Use the correct transmission fluid
Sensor Issue
• Avoid driving the vehicle until repaired to prevent further damage.
• Consult a professional mechanic for diagnosis and repair.
Check with your vehicle manufacturer or dealership for warranty coverage related to the transmission system.
This code has been reported more frequently in vehicles with high mileage or those that have not been regularly maintained.
Moderate – It should be addressed soon to avoid potential transmission damage.
Driving with a malfunctioning transmission system can be dangerous and may lead to further damage.
• Engine running
• Transmission in operation
The electric/auxiliary transmission fluid pump is typically located near the transmission assembly.
Q: Can I drive with a P27E6 code?
A: It's not recommended as it may lead to further transmission damage.
Q: How can I prevent this code from occurring?
A: Regular maintenance and inspections of the transmission system can help prevent this issue.
