89-07 Dodge 5.9L Cummins Full Send Diesel Temperature Control Transmission Pan

Fits: 1989-2007 Dodge 5.9L Cummins

This is FSD’s fabricated aluminum temperature control transmission pan. This pan not only looks cool but has a few functions that set it apart. For years customers have been struggling with the factory heat exchangers on their trucks failing and causing transmission fluid and coolant to mix. In return it destroys their transmission. Unfortunately there are absolutely NO alternatives to this heat exchanger failing other then bypassing it with either one of our transmission or heater hose kits, which is fine ONLY if you live where it’s warm year round or you don’t drive the truck when it’s cold. The reason you don’t want to bypass it when it’s cold is because your transmission will not get up to operating temperature until you drive it and work the truck to get it to build heat. The issue with that is that you're still driving the truck when the fluid is extremely cold and way below operating temperature. On top of that, once you get on the highway or take a long drive, your trans temp will plummet and not stay near operating temp causing damage to the transmission. When transmission fluid isn’t at the proper temperature it can cause all kinds of odd shifting issues in your transmission, the fluid breaks down faster and most importantly it cannot properly lubricate the parts inside of your transmission if it’s too cold. Driving with cold fluid has negative long term effects on your transmission. We have spent dozens of hours studying, designing and testing our new pan and methods of exchanging heat. We have made our own version of the factory heat exchanger, that is also deep transmission pan but it WILL NOT FAIL. To make it simple, our pan has a billet bottom that allows coolant to flow through the bottom of the pan and help warm the transmission fluid in cold climates. We tested this using the same truck with the same outside temperature. 


Fitment & Installation

Mounts to any 47/48RE Transmission

The two coolant lines that need to be run need to circulate. We achieved the best circulation by running one line into the port that normally feeds the factory heat exchanger. (1989-2002 trucks it’s on the passenger side. 2003+ trucks it is on the driver side.) Then we T’d the other coolant line into the one heater core hose that goes up to the front of the engine under the alternator. 

As for the transmission lines, you can run the factory ones if you would like but the fluid would still go through the factory heat exchanger, you can purchase our bypass transmission line kit if you don’t already have it. A cheaper option would be to jump the two factory hoses together. 

As for coolant lines, you will need our lower heater hose if you don’t already have it or else when you disconnect the feed to the factory heat exchanger on the coolant side to run your hose to our pan, coolant will will come out of that hose you disconnected. A cheaper option would be to cap it off.
