P0218 on Dodge
Transmission Over Temperature Condition
P0218 on Dodge vehicles indicates transmission over temperature condition. Au7o has documented this code across 1 Dodge model — most commonly on Grand Caravan. This code means the transmission fluid has gotten too hot and exceeded a safe temperature limit. The transmission's temperature sensor reported an overheat condition to the computer, which can be caused by an actual overheating situation or by a faulty sensor reporting a false reading. Excessive heat is one of the most damaging things for an automatic transmission, breaking down the fluid and accelerating wear, so this code should be addressed promptly. The vehicle may enter a reduced-power or limp mode to protect the transmission. Typical repair costs on Dodge range from $150 to $400, depending on the specific model and root cause.
Common Causes of P0218
- •Low or old/degraded transmission fluid
- •Faulty transmission fluid temperature sensor
- •Clogged or restricted transmission cooler or lines
- •Heavy load/towing or stop-and-go driving overheating the fluid
- •Slipping clutches generating excess heat
- •Faulty cooling fan or radiator (shared cooling) issues
- •Internal transmission wear or restriction

- Transmission Cooler Line Leak at Radiator Connection2008-2020
The transmission cooler lines that connect to the integral transmission cooler in the radiator develop leaks at the quick-connect fittings and at the rubber-to-metal transition points. The factory quick-connect fittings become brittle and crack, and the rubber hose sections deteriorate from heat exposure. Slow ATF loss goes unnoticed until the transmission begins slipping or overheating. This is a leading cause of 62TE transmission failures in the Grand Caravan.
