Transmission Component Slipping
The P0894 code means the vehicle's onboard diagnostic system has detected: Transmission Component Slipping. This is a critical severity code.
- Keep driving?
- No — stop driving
- DIY difficulty
- hard
- Estimated cost
- $100 - $1,500 (parts and labor)
Read and clear transmission codes. Many trans codes are caused by low or burnt fluid -- check level and color before assuming the worst.
Basic scanners only read engine codes. This reads transmission, ABS, and airbag too.

2003-2016 Nissan Altima/Rogue CVT Easy (fluid), Advanced (CVT replacement) DIY
Transmission component slipping on Nissan CVTs is a critical code indicating steel belt or pulley wear. If the CVT is juddering or shaking during acceleration, the belt is slipping on the pulleys. Check CVT fluid condition -- metallic particles or a burnt smell confirms internal damage. Nissan extended the CVT warranty on many models to 10 years/120K miles under warranty extension A CVT replacement is typically required. Your dealer can confirm whether an open service bulletin or warranty extension applies to your VIN.
Labor: 30-45 min (fluid), 8-12 hours (CVT replacement)2007-2018 GM Cruze/Malibu 6T70/6T75 Moderate (cooler), Advanced (rebuild) DIY
Component slipping on the GM transaxle is usually caused by a worn 3-5-reverse clutch or 4-5-6 clutch pack. This code often appears after extended driving with low or contaminated fluid. Check fluid level and condition first. If fluid is burnt, the transmission needs a rebuild. GM issued a service bulletin covering updated clutch materials for 2013-2016 models. An auxiliary cooler helps prevent future overheating. Your dealer can confirm whether an open service bulletin or warranty extension applies to your VIN. Confirm the exact part for your year and engine with a retailer's fitment lookup or your VIN before ordering - these applications split by engine and build date.
Labor: 1 hour (cooler), 10-12 hours (rebuild)2005-2017 Ford F-150/Explorer 6R80 Easy (fluid), Advanced (rebuild) DIY
Transmission slipping on the 6R80 can be caused by worn clutch packs, a failing torque converter, or low line pressure. Use Ford IDS to read clutch slip counts and adaptive pressures. If adaptive values are at maximum, the clutches are worn beyond compensation. A torque converter shudder can also trigger this code -- a fluid change with Motorcraft Mercon LV and converter drain sometimes resolves converter-related slipping.
Labor: 30 min (fluid), 10-12 hours (rebuild)2001-2014 Honda Accord/Odyssey Automatic Advanced DIY
Slipping on Honda automatics is the final stage of clutch pack failure. Honda transmissions from this era are known for premature failure, especially the Odyssey and V6 Accord. If slipping is confirmed, a rebuilt or remanufactured transmission is the most reliable fix. Honda OEM remanufactured transmissions come with a 3-year warranty and are often more reliable than aftermarket rebuilds.
Labor: 6-8 hours (transmission replacement)Frequently Asked Questions
What does P0894 indicate?
P0894 indicates a problem with the transmission component slipping. This is a critical issue that can prevent the transmission from operating correctly.
Can a weak battery cause this code?
Yes. TCM modules are sensitive to voltage supply quality. A weak battery, poor connections, or charging system issues can cause various TCM power-related codes. Always test the battery and charging system first.
Do I need a TCM replacement?
Not necessarily. Most TCM codes are caused by external issues like power supply problems, relay failures, or wiring faults. A TCM replacement is typically only needed when all external causes have been ruled out.
