This summary uses the existing diagnostic information shown in full below.
The car's computer thinks the transmission fluid, which helps the car change gears, is old and not working well anymore.
The code P0897 indicates that the vehicle's transmission control module (TCM) has detected that the transmission fluid has deteriorated beyond acceptable levels.
Transmission fluid is essential for lubricating the moving parts within the transmission, cooling, and providing hydraulic pressure. Over time, the fluid can break down due to heat and contamination, losing its effectiveness. This code is triggered when sensors detect that the fluid's properties have degraded to a point that could affect transmission performance.
• Harsh or delayed shifting
• Transmission overheating
• Poor fuel economy
• Old or contaminated transmission fluid
• High transmission temperatures
• Faulty transmission fluid temperature sensor
Transmission Fluid: A liquid used to lubricate and cool the components of a vehicle's transmission.
Transmission Control Module (TCM): An electronic device that manages the operation of a vehicle's transmission.
• Check the transmission fluid level and condition.
• Inspect for any leaks in the transmission system.
• Test the transmission fluid temperature sensor.
• Replace the transmission fluid and filter.
• Repair any leaks found in the transmission system.
• Replace the faulty transmission fluid temperature sensor if needed.
• OBD-II scanner
• Transmission fluid dipstick
• Basic hand tools

Moderate
• Chevrolet Silverado
• Ford F-150
• Toyota Camry
• Regularly check and change transmission fluid.
• Ensure proper cooling of the transmission system.
• Avoid excessive towing or heavy loads.
Transmission Performance
• Have the transmission fluid checked regularly.
• Be attentive to any unusual transmission behavior.
• Schedule regular maintenance with a trusted mechanic.
Transmission issues may be covered under the powertrain warranty. Check with the manufacturer.
This code has become more common as vehicles age and transmission fluid maintenance is often neglected.
Moderate – Addressing this issue can prevent more severe transmission damage.
Driving with deteriorated transmission fluid can lead to unsafe driving conditions and further vehicle damage.
• Vehicle at operating temperature
• Transmission fluid level checked
Transmission fluid is located in the transmission pan, typically at the bottom of the transmission.
Q: What happens if I ignore this code?
A: Ignoring this code can lead to transmission damage and costly repairs.
Q: Can I drive with this code?
A: It's not recommended to drive for long periods with this code as it can cause further damage.
