What does P0894 mean?

Transmission Component Slipping
Code P0894 stands for Transmission Component Slipping. This code can mean either an internal transmission component is slipping, or the torque converter is slipping.

What can cause a P0894 code?

What are the Possible Causes of the P0894 Code?

• Low level of transmission fluid.
• Defective control solenoid.
• Failing torque converter.
• Internal transmission issues.
• Faulty input or output speed sensor.
• PCM/TCM failure.

How do I fix error code P1870?

What Repairs Will Fix P1870?

1. Change the transmission fluid//flush the transmission.
2. Install a high quality in-line transmission filter.
3. Repair worn transmission valve bores.
4. Replace TCC clutch.
5. Reprogram ECU.

What causes code P1870?

As stated earlier, DTC P1870 is produced when the PCM sees a breakaway in the slip ratio while at a cruise. If the ratio breaks away, the cause could be compromised trans components, hydraulics or electronics.

What does a TCC valve do?

The (TCC) torque converter clutch creates a one-to-one connection between the engine and the transmission that increases fuel mileage and reduces transmission fluid temperatures.

What is a transmission component?

Automatic transmissions have planetary gear sets that consist of the sun gear, planet gears, and ring gear. These gears move and interact together, which allows the car to attain a range of forward and reverse speeds. Clutch.

What does the p0894 code on the OBD-II mean?

The P0894 trouble code detects an issue with the vehicle’s automatic transmission component. The P0894 code is an OBD-II trouble code signaling a problem with the transmission component slipping.

What does the p0894 code on the PCM/TCM mean?

The PCM/TCM monitors the difference between engine speed and transmission output speed. When the converter is engaged, engine speed should closely match transmission output speed. Code P0894 indicates the PCM/TCM has detected excessive TCC slippage.

What does the p0893 code mean on a GMC Sierra?

P0893: Code P0893 indicates the PCM has detected multiple gears engaged at the same time. P0895: Code P0895 indicates the PCM has detected the transmission shift time is too short. P0896: Code P0895 indicates the PCM has detected the transmission shift time is too long.

What does the p0895 code on a GMC Acadia mean?

P0896: Code P0895 indicates the PCM has detected the transmission shift time is too long. Code P0894 is often found on General Motors vehicles ( Buick, Cadillac, GMC, Chevrolet) and may have accompanying technical service bulletins.
