How to diagnose and fix P0218: most-reported vehicles
Ranked by owner reports. Each card gives the symptoms, how to confirm the cause, the fix, parts and sources for that vehicle.
Nissan NV · 2012–2021
The Nissan NV 1500/2500/3500 V6 models and 2012-2016 V8 models use a 5-speed automatic transmission (RE5R05A), and 2017-2021 V8 models use a 7-speed automatic; these can overheat under heavy load conditions — particularly when the van is loaded to its GVWR in hot weather. The factory transmission cooler is marginally sized for commercial use. Overheating degrades the ATF, causing the torque converter clutch to shudder and the shift quality to deteriorate. The NV 3500 passenger van with full seating capacity is especially prone.
Common Symptoms
- Transmission overheating warning when fully loaded
- Harsh or delayed shifting after extended highway driving
- Torque converter shudder at 40-50 mph
- Transmission fluid dark or burnt smell
- Reduced tow rating performance
How to Fix
Install an auxiliary transmission cooler with a thermostat — this is the most important modification for any NV used commercially. Change ATF every 30,000 miles with Nissan Matic S fluid. If shudder is already present, a fluid flush with new ATF can resolve early-stage torque converter clutch issues. A transmission temperature gauge helps monitor temperatures during heavy loads.

Verify VIN, transmission code, quantity and temperature-based level procedure.

A qualified installer must confirm space, capacity, adapters, hose pressure/temperature rating, series routing and any separate thermostat before purchase.

Owner tips & cautions
- TipChange ATF every 30,000 miles with Nissan Matic S — the factory "lifetime fill" recommendation is for passenger car duty, not commercial van use
- WarningAn auxiliary transmission cooler should be considered mandatory equipment for any NV used for delivery, passenger transport, or towing

Chrysler Prowler · 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. This happens even though the car has a factory transmission oil cooler (Mopar 4786466AC on the 2002 Prowler).
Common Symptoms
- Transmission slipping during spirited driving
- Harsh or delayed shifts after extended driving
- Burning ATF smell from rear of vehicle
- Transmission fluid dark or burnt on dipstick
- Limp mode after aggressive driving (shift to 2nd only)
How to Fix
Install an auxiliary transmission cooler with a thermostat to maintain optimal temperature. Route the cooler lines to the front of the vehicle where airflow is available. Change the ATF+4 fluid every 20,000 miles — the rear-mounted transmission runs significantly hotter than a front-mounted unit. A temperature gauge adapter in the cooler line helps monitor transmission temperature. Avoid stop-and-go driving on hot days.

Nissan Rogue · 2014–2020
Separate from the well-known JATCO belt/pulley judder, many 2014-2020 Rogues suffer CVT failure driven specifically by inadequate fluid cooling. The factory cooling circuit struggles in heat, towing, or hilly/stop-and-go use; CVT fluid overheats, the TCM commands a protective 'limp' mode (power cut to protect the unit), and sustained heat permanently degrades the belt and pulleys. Cooler-line leaks and contaminated (brown) fluid accelerate the cycle. Nissan addressed related overheating on earlier Rogue/Rogue Select with a TSB calling for an auxiliary trans-cooler kit, underscoring the thermal-management root cause.
Common Symptoms
- Transmission overheating warning
- Sudden loss of power / limp mode
- Shuddering on acceleration
- Whining noise from transmission
- Brown or burnt-smelling CVT fluid
How to Fix
Verify the failure mode with a CVT fluid temperature scan and inspect cooler lines for leaks/restriction and fluid for overheating (dark/burnt) signs. Remedy is restoring cooling capacity: replace a clogged factory cooler, repair leaking lines, install an auxiliary/aftermarket CVT cooler for towing or hot climates, and flush to fresh NS-3 fluid. Severe heat damage requires CVT rebuild/replacement.

Frequently asked questions
What does P0218 mean?
P0218 stands for "Transmission Over Temperature Condition." 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.
What are the most common causes of P0218?
The most common causes of P0218 are: 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. The specific cause varies by vehicle.
How much does it cost to fix P0218?
Repair costs for P0218 range from $150 to $5,000, depending on the vehicle and root cause.
