• The fault code P0218 indicates that there is an issue with the transmission temperature exceeding normal range.

Possible Symptoms:

  • Illuminated check engine light

  • Harsh shifting between gears

  • Vehicle may go into "limp mode"

  • Reduced performance and acceleration

  • Transmission may overheat and cause damage if not addressed promptly.

Possible Causes:

  • Low transmission fluid levels

  • Faulty thermostat

  • Malfunctioning temperature sensor

  • Clogged or damaged transmission cooler lines or cooler

  • Overworking the transmission, such as towing a heavy load for an extended period or aggressive driving

Related Parts:

  • Transmission Fluid Temperature Sensor: Gear fluid line delivers gear fluid/oil between the various gear parts that need lubrication. The Gear fluid temperature sensor monitors the fluid temperature in the line. Problems lead to difficulty in shifting gears

Possible Solutions:

  • Check and refill the transmission fluid level

  • Replace the thermostat if necessary

  • Repair or replace the temperature sensor

  • Clean or replace the transmission cooler lines or cooler if clogged or damaged

  • Avoid overworking the transmission by reducing the load on the vehicle or driving less aggressively
