P0897
Transmission Fluid Deteriorated
Transmission / fluid condition
Generic OBD-II
Low
What it means
P0897 means the system has determined the transmission fluid has aged or degraded beyond acceptable limits, usually from mileage, heat, or a low level. The engine and transmission still work, but worn fluid shifts less smoothly and protects internal parts less well, so the main fix is a proper fluid service before it leads to bigger wear.
Low
Can I keep driving? Driveable, but the fluid is worn out — service it soon to avoid harsh shifting and long-term transmission wear.

How to diagnose & fix
Work through it in order
- Check fluid level, colour, and smell; dark or burnt fluid confirms deterioration.
- Service the transmission fluid (and filter) with the correct specification fluid.
- Reset the fluid-life counter if the vehicle uses one.
- Inspect for causes of overheating (cooler/flow) if fluid degraded early. Clear and re-test.
FAQ
Quick answers
Is it safe to drive with P0897?+
Yes, short-term — but worn fluid loses its ability to protect the transmission. Service it promptly to avoid shifting problems and wear.
Can I just clear P0897?+
Clearing without changing the fluid just resets the light; on many vehicles it returns until the fluid is serviced and the counter reset.
