Dodge Transmission
Sent to Car Experts August 16 10:26 AM

I have a 2002 Dodge Durango with a 5.9 and a 46RE transmission. I have added a auxillary stack plate cooler and a deeper trans pan. When I pull my trailer the trans temp gets up around 210 degrees. Normal operating temp is about 150 degrees. I thing the trans is slipping a bit when I tow and this is causing the rise in the temp. Is there a trans pac kit to bring the line pressure up and fix this problem and if so where do I get it.

 

Optional Information:
2002 Dodge Durango 5.9

Already Tried:
nothing other than the cooler and pan

How big is the trailer? Did you have any trans problem before or when you are not towing? Do you know what your line pressure is reading at?

Reply to Brian W.'s Post: The trailer is well within the 7300 pound towing capacity of the vehicle. I do not know what the line pressure is but I have a pressure gage to check this. I do not have any issues with the trans when not towing other than the shift points are a little short.

Last post you stated you had a pressure gauge to test line pressure, I did not recieve any results.

Usually lack of line pressure and a overheating trans is due to a faulty front pump. On our scan tool drb3 we have an option to moniter line pressure and desired line pressure, if the actual strays from the desired a reading must be taken. If pressure is actully low the pump and reaction shaft must be inspected and checked with a feeler gauge.

It sounds like you have a weak pump, that only becomes a problem under load.
