P0218 on Chrysler
Transmission Over Temperature Condition
P0218 on Chrysler vehicles indicates transmission over temperature condition. Au7o has documented this code across 1 Chrysler model — most commonly on Prowler. 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 Chrysler range from $200 to $3,000, 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
P0218 on Chrysler by Model
Chrysler Prowler(1 issue)
- 42LE Automatic Transmission Overheating (Rear-Mounted)1999-2002
The Prowler uses a unique rear-mounted Chrysler 42LE 4-speed automatic transaxle with the differential integrated into the unit. The transmission is mounted at the rear axle (like a Corvette) for weight distribution, but the rear mounting location receives less cooling airflow than a front-mounted transmission. Combined with the 3.5L V6's torque, the 42LE overheats during spirited driving, causing shift quality degradation and premature clutch wear. There is no factory auxiliary cooler.

What does P0218 mean on Chrysler?▼
P0218 stands for "Transmission Over Temperature Condition." This code means the transmission fluid has gotten too hot and exceeded a safe temperature limit.
