P270DTransmission Friction Element D Temperature Too High
- Generic OBD-II code · Powertrain
- Can trigger limp mode
- How the car detects it
- P270D is stored when the thermal state of shift element D rises above the controller's limit. The heat comes from friction during slip, so anything that lengthens slip on D counts: a sluggish apply, leaking seals in its hydraulic circuit, or hard use with a heavy load. Cooling also matters, because the fluid carries the heat away; a blocked cooler, a low level or oil that has lost its properties make the code more likely. Publicly, no manufacturer documents P270D or its thresholds, and the letter must be matched to a clutch with the specific gearbox data. CARB treats transmission controls as monitored powertrain components. For the driver the code mostly means a protective torque or gear limit; it does not by itself prove mechanical damage, but it should be investigated if it returns.
- What you may notice
- Limited torque or gear range for protection
- Transmission temperature warning
- Flare or slip on shifts involving element D
- Likely causes
- LikelyLeaking seals in the apply circuit of element D lengthening slip
- PossibleBlocked or undersized fluid cooler, especially when towing
- PossibleOld or wrong fluid with reduced friction and cooling properties
- RareWorn plates of element D
