DODGE RAM transmission oil cooler does not cool in park???? Is this true?

Ive heard from a few not-so-reliable sources (friends) that the current generation Ram trucks do NOT cool the tranny fluid if the truck is in park. therefore, they say that if i was gonna be leaving it idle in park for any amount of time, i should turn it off, or put it in neutral so that i dont overheat the tranny....this sounds like crap to me. but, i dont know technical stuff about it, so was wondering if anyone knows whether theres truth in this or not??? i was told that Fords and GMs dont have this problem. one person i heard this from is a Dodge fan, and he agreed that he has heard this. is it true?DODGE RAM transmission oil cooler does not cool in park????

Lets see, the pump is connected DIRECTLY to the crankshaft via the flex plate, so HOW could it NOT pump???? Come on the fluid flow may not be directed to the cooler but in my experience with flushing transaxles the fluid DOES flow directly out of the TC, into the cooler circuit for max cooling, and it is a liquid to liquid cooler so even if the vehicle is not moving there will be some cooling effect going on. Even if the cooler is an aux. cooler not part of the radiator ';in tank '; cooler it will be exposed to the atmosphere giving it some cooling effect. I understand all mopars to be mostly the same and to not allow for cooling in park would seem to be foolish, provided all the failures due to heat.DODGE RAM transmission oil cooler does not cool in park????

WOW!! I DIDN'T KNOW THAT SO MANY OF YOU ASE MASTER TECHS COULD BE SO WRONG!!! DODGE TRANSMISSIONS USED IN THE FULL SIZE TRUCKS DO NOT FLOW TO THE COOLER IN PARK. YES THEY PUMP FLUID ALL THE TIME HOWEVER IT COMES FROM THE PUMP TO THE VALVE BODY AND THEM IF IN PARK IT GOES BACK TO THE PAN!!!! PERIOD Report Abuse

if you don't believe that it cools in park try taking the line of the cooler and see how much fluid will come out of it,you,ll loose all of it in a matter of a few minutes,anytime the engine is running the fluid is flowing through the cooler,it doesn't have to be in drive or any gear for it to flow,the pump works all the time,try it if you don't believe it does,but be prepared to clean up a big mess,ever who told you this obviously isn't a mechanic,good luck.
I guess I am not a mechanic either. Mine always had to be in gear for fluid to flow through the cooler. Tried to reduce over fill by disconnecting the cooler line, rather than pulling the pan. No fluid came out until I put it in Drive. Actually it would have pumped it out in neutral.


Regardless, unless you are in the middle of the desert, the transmission will not over heat.


The price of gasoline is the main worry now.
the oil cooler does not cool in park because the pump does not pump in park. it only sends fluid thru the cooler in r n d 1 2 . thank you owner of 95 dodge ram 1500 4x4 237,000 all original motor %26amp; trans.
well yeah the tranny cooler needs air going through it to do its job so YOU NEED TO BE MOVING for it to work - just like a radiator
That's BS, if the engine running fluid fows in a circle. And the cooler is in that circle.
