P0218

Transmission Over Temperature Condition

DTC P0218, sometimes indicated as P021800 is an OBD diagnostic trouble code indicating a generic fault with the vehicle powertrain (i.e. engine and gearbox). This code identifies an error with the air/fuel mixture causing transmission over temperature condition.

The most common cause of this code is a transmission fluid leak. Other causes can include a defective transmission cooler, a defective thermostat, or a defective fan clutch.
If a transmission fluid leak is the cause, it must be repaired before the code can be cleared. If a defective transmission cooler, thermostat, or fan clutch is the cause, those parts should be replaced as necessary.

2015 CHRYSLER 200 with 39400.0 miles

I was driving home from work when the check engine light, engine temperature warning light, and electronic throttle control light came on. In reviewing the potential issues, a number of people have had the same issue, potentially due to a faulty thermostat. When i had the vehicle scanned at autozone, it provided codes P0218 twice and P2181 once.

2009 JEEP PATRIOT 4X4 with 122300. miles

During highway driving at a sustained speed of high rpms, the transmission temperature warning light comes on. If speed is not reduced to allow the transmission to cool, the car goes into a safety mode and slows automatically. A repair shop pulled the codes and found code P0218, high temp operation activated. This problem occurs multiple times on almost every long highway trip when trying to maintain speed going up hills. The increased acceleration keeps the engine operating at high rpms above 3000 for a sustained period of time.

2009 DODGE CALIBER with 52000.0 miles

Tl* the contact owns a 2009 Dodge Caliber. While driving approximately 50 mph, the transmission warning light illuminated on the instrument panel and the vehicle became hesitant to acceleration attempts. The vehicle was taken to the dealer for diagnostics where the technician replaced the transmission fluid and filter. The failure continued after the repair. The contact added transmission fluid to the vehicle but the failure persisted. The vehicle was taken back to the dealer where the technician advised that the transmission would have to be replaced because the incorrect transmission fluid was used by the contact. The contact stated there was no warning label on the vehicle stating which type or brand of transmission fluid had to be used in the vehicle, nor was there a dip stick to check the fluid. The vehicle was not repaired. The approximate failure mileage was 52,000. Updated 08/14/12*lj the consumer stated a code for the transmission, which read P0218 meant the transmission overheated. Updated 08/16/15

2006 DODGE DAKOTA with 72570.0 miles

5/06/09, i went to a Dodge dealership because "check engine" light kept coming on & off. This was an ongoing incident that took place on other occasions throughout my ownership of vehicle, but whenever taken to original dealership, the light was no longer on, & the dealership would state they could not find anything & suggested i bring the vehicle back whenever it came back on. On this latest incident, light remained on & dealership stated that they would "need to remove transmission and break down to find internal failure or replace transmission." the codes that showed up were "P1775, solenoid switch valve latched in ttc position" and "P0218, trans-high temp activated." they were siding on replacing transmission stating that i had 72,570 miles on vehicle. I inquired if under warranty, & they stated that i had exceeded the mileage & my vehicle had just passed the 3 year mark the day prior. I then filed a claim w/Dodge headquarters on 5/7/2009 to inquire about any recalls or assistance w/a new transmission. I had inquired about recalls because i have always kept up w/my routine maintenance, the vehicle was bought new & had just made 3 years & the miles were mostly highway miles. After several followup calls on 5/8/2009, 5/14/2009 & 5/19/2009, Dodge corporate office informed me that they spoke to the dealership, & though rebuilding or replacing the transmission was ideal, they would not assist me w/doing such because my warranty had expired. Additionally, original dealership i had purchased my vehicle from had went out of business, & Dodge customer service stated they could not find any record of me bringing vehicle in for same problem. The only thing they offered was reimbursing the $213.98 i paid to have the truck diagnosed, but after submitting my receipt to them. Dealership could not reverse the transaction to reimburse. Since then, i've had other places look at vehicle who tell me they've seen similar problems w/other Dodge trans of that year. Trans now slipping.
