Hello I have a 2008 Dodge Ram SXT 3.7 liter V6 with a 42rle transmission I just recently had the transmission rebuilt and the day I got it back I can't get the trans cooler light to quit coming on. We added a bigger trans cooler still didn't fix it any help on this matter would be appreciated and how do you get this son of a gun to quit leaking new gaskets new everything and it still leaks and it gets hot one more thing how do you test the sensor maybe it's bad any help

 

Are you actually getting flow thru the cooler? Is there a check valve in the system somewhere? Was the cooling circuit flushed when the trans work was done?

 

Shop has decided that we need to change the trans lines.
