A fault code doesn’t yet mean the unit or sensor itself is faulty: often it’s the plug and connector leading to it.
Possible causes
- Long driving in traffic, towing or uphill
- Low or old transmission fluid
- Transmission cooler clogged on the outside
- Transmission fluid temperature sensor
What you can do yourself
- Stop and let the transmission cool for 10–15 minutes.
- Check the gearbox fluid level and condition.
