OBD-II Code
P0894
Severity
Not yet reviewed
Nobody on our side has assessed this code yet, so we are not going to guess at how serious it is.
Can you drive it
We cannot say
Treat it as unknown until a shop reads it with live data. If the check-engine light is FLASHING, stop driving as soon as it is safe to — that means an active misfire, whatever the code.

From this code's diagnostic notes. Varies by vehicle, diagnosis, parts, and local labor. This is not a repair quote.
P0894 is a transmission component slipping code, set when the TCM measures input shaft speed and output shaft speed and calculates a gear ratio that does not match the commanded gear within tolerance, indicating a clutch pack or band is slipping rather than holding.
How a shop works this
Work from evidence to part, not the other way round. A code names a circuit or a symptom; it does not name the part that failed.
Note every code that is set, not just this one.
Codes that appear together usually narrow the cause faster than any one of them read alone.
Read the freeze frame — the conditions the fault was recorded under.
Cold or warm, idle or load, road speed and engine speed. A fault that only appears cold is a different fault from one that only appears under load, even with the same code on the scanner.
Confirm the fault is current rather than history.
Clear the code and see whether it returns under those same conditions. A code that does not come back may have been logged during a repair, a flat battery, or a bad connection that has since been disturbed.
Then follow the diagnostic notes further down this page, in the order they are written.
They are written in the order a shop works this code, cheapest checks first. Where they name a component, inspect its wiring and connector before replacing it.
If the code comes back after a repair, the underlying fault is still there. That is the point to bring in a scanner with live data and freeze-frame, or a shop that has one.

Cheapest first
- check transmission fluid level and condition (warm, on level ground, engine running, in the manufacturer-specified gear); low fluid causes slip, and burned or dark fluid with a varnish smell indicates internal wear that no external fix will cure.
- Scan-tool the input and output speed sensors and verify both report plausible values during a road test; a failed input or output speed sensor will fake a slip code, and replacing the sensor for $80 is far cheaper than a transmission rebuild.
- Caveat: a true component-slipping code with verified speed sensors and clean fluid does mean internal damage, and continuing to drive a slipping transmission accelerates the damage exponentially.

- 2003to 2010 Honda Accord, Odyssey, Pilot, and Acura MDX/TL with the 5-speed automatic have a famous 3rd-clutch and torque converter failure pattern that sets P0894, often paired with a hard 2-3 shift flare; Honda extended the warranty on certain VINs.
- 2006to 2010 Chrysler 300, Dodge Charger, and Magnum with the W5A580 set P0894 from torque converter clutch shudder that progresses to actual slip.
- 2007to 2012 Nissan Altima, Maxima, Murano, and Pathfinder with the JATCO RE0F09A/B CVT trips P0894 from belt or pulley wear.
- 2004to 2008 Ford F-150 with the 5R55W/S transmission shows P0894 from band wear and TCC failure.
