transmission cooler

Anyone here use a transmission cooler with fan and thermostat for their autos? Any part #'s or a place where I could order this?

Thank You.

I think there may be something in the sticky about it. I know I was just reading a write up by Jim Lane last week or the week before. Do a search, I'm sure there's loads of stuff. I have a factory installed, (oh ok, a dealer installed!!) one on mine, so I can't help with part #'s etc. Works great though!

Is Yours a cooler with a fan controlled by a thermostat? I read the part You say dealer installed, is this a factory or aftermarket cooler?

I'm looking for this specific type of coolers and if it is something I can get at a regular parts store even better.

Thank You.

Here is my story on the Super Duty Transmission Oil Cooler,

https://www.dieseltruckresource.com/...r-t264993.html

Here is a link to some fin and plate design oil coolers with shrouded electric cooling fans.

You want to get the highest BTU rating you can afford that will fit your application and a minimum of 1/2 "oil lines.

Exekiel, if you haven't already, read Jim's thread. It will give you EVERYTHING you will need to know . Jim's threads are so good Cummins should be paying him squillions to write their service manuels.

I'm not the one to ask about where the dealer sourced the cooler from. IIRC, later on in Jim's thread there is a question about who installed the coolers when the truck was bought new, and the answer was the dealers. I'm not the original owner, so didn't specify that option. And besides that, these trucks are getting old now, and the technology used on them is not going to be as good as a new/aftermarket one.

Wow, now that is a good thread. I found a cooler with fan and a thermo switch on the link You posted. I'll call them today and see if it works for the truck I want it for.

Thank You.

When you install the remote cooler I would supply it with at least an 8-gauge wire to supply the motor with all of the current it needs, have the thermostat trigger a 40-amp Bosch relay near the fan, connect the opposite end through a fuse link directly to the battery terminal.

I would also install a switch to manually control the blower motor.
I have mine controlled manually with a switch in the cab.

I hope this gives you some ideas.

Jim

So could you just have a cooler mounted under the bed without a fan? Or would that be worthless?

I'm trying to acquire a 3rd gen transmission cooler.

Yes? No?

Another idea I might try is mount the 3rd gen cooler under the bed. Have 3 way valves to it. When towing open the valves so the fluid flows through it. When not towing close the valves so the fluid bypasses it and just goes back into the transmission.

How does that sound?

You could also go the route of a Mag hytec double deep transmission pan
I got one, my temps have never went over 140 since.

(but I have a goerend triple disc and goerend trans, which most likely doesnt create the heat a stock trans does)

I run the DD pan and can attest to it's cooling properties. There is simply so much more fluid when you run the pan.

Question Stupid question perhaps?

Overheated transmission fluid is obviously dangerous; but it was mentioned in a recent thread that tranny fluid being too cold isn't good either. (And therefore the liquid-to-liquid heat exchanger under the turbo serves two purposes -- to cool off hot tranny fluid and to warm up cold tranny fluid.)

For a truck that is used for towing only occasionally, is it possible that a double deep pan (or an auxiliary transmission cooler) might keep the transmission fluid too cool?

TIA.

The only time we ever have problems with the trans fluids being too cold is when it is -40 out. So unless your new cooler somehow violates the laws of thermodynamics I do not believe you can over cool a fluid.

Yeah, I just let it circulate and warm up along with the engine when it's cold out, and then take it easy for a few miles.

I thought a 518 only pumps fluid in gear or nuteral
