i have a 2006 dodge dakota 4.7L auto 2Wd, and i am having that P0218 code come up randomly saying the trans. fluid temp is high. fluid temp is running between 189 degrees and then spike to 384 degrees then instanly it drops back down. took to a trans shop here local and they put a new solenoid pack with a trans temp sensor built in and the problem is still occuring randomly. when the trans temp light does come on and set the trouble code it does put the transmission into a fail safe mode. Does anyone have any possible fix for this?

 

I will move this to the 3rd generation Dakota sub-forum.

 

Tex,

Below is the theory of operation and possible causes. Not sure if this will help but posting it just in case.

P0218-HIGH TEMPERATURE OPERATION ACTIVATED



Theory of Operation

The DTC is intended as an informational DTC to aid the technician in determining the root cause of a customer dirveability issue. The DTC is also intended to alert the technician to determine if a cooling system malfunction has occurred or if an additional transmission air to oil cooler is needed to support the customers driving behavior.

• When Monitored: Whenever the engine is running.
• Set Condition: Immediately after a Overheat shift schedule is activated when the Transmission temperature exceeds 127° C or 260° F.

Possible Causes

HIGH TEMPERATURE OPERATION ACTIVATED
TORQUE CONVERTER CLUTCH SLIPPING / NOT ACTIVATING
OPERATING VEHICLE WITH TRANSMISSION IN LIMP-IN MODE FOR AN EXTENDED PERIOD OF TIME
EXCESSIVE TIME IDLING IN GEAR

 

thanks that helped alot in being able to diag. the problem. i was to figure out the problem was not only a clogged trans cooler and bad selinoid pack i also head i broke exhuast just behind the right side (bank 2) cat convertor that i welded back together and i have been happy to say that so far the problem is fixed. crossing my fingers that nothing esle shows up now

 

I hope the issue is resolved.
