P275B Transmission Fluid Temperature Sensor D Circuit Range/Performance
The fourth transmission fluid temperature sensor reading is implausible. Wiring faults of this kind typically come from chafing, water ingress at connector seals, or pin push-back — a wiggle test on the harness while the code is active often confirms the location.
Is it safe to drive with P275B?
Usually safe to drive in the short term. Get it diagnosed when convenient, sooner if the car drives differently.
Common causes
- PossibleSensor drift after thermal aging
- PossibleSensor not seated properly in the fluid path
- Less likelySensor element aged beyond calibration window
Symptoms
- Check engine or transmission warning light on
- Harsh, delayed, or missing shifts
- Possible limp mode (locked in one gear)
- Slipping or shuddering during gear changes
