Torque converter cooler

I have a really dumb question that I've mulling over doing.

Transmission was still getting warm plowing last winter. Only thing I got left for ideas is possibly getting a small electronic fan to attach to the torque converter cooler next to the engine to help cool things off. But I don't know if this is a really idiotic idea or not.

Most people add an Auxiliary cooler with a fan, and thermostat to deal with temps

You mean like what BD diesel has with a remote aux cooler?

Adding a fan to that will do nothing. It’s not like a rad with fins where it’ll pull heat away. a good upgrade would be to add an additional auxiliary cooler with its own fan. That will keep it cool.

Did the front cooler leak and clog itself with dirt?
Delete the thermostat in the cooler for starters. Should help a good bit in the winter months..

Yes, I have one of their double stacked coolers. Derale makes a bunch of them also, but the BD is plug and play with wiring and thermostat in a kit. Pretty nice. I also deleted the heat exchanger, but if you live in snow country I'd keep it for the winters because it will heat your fluid up faster.

The stock cooler is only 1/2" thick, and is a tube and fin type is not very efficient. Stack pl8 design is best and the Derale are a full 2" thick for literally 4X the cooling as stock and 2X the cooling as the Mishimoto replacement cooler for 1/2 the price!!! The brackets I made are also 6061 Aluminum so the whole assembly is one big heat sink.

This is the setup I typically install when MAX cooling is needed. Between the cooler thermostat delete and this setup, you will not have any temperature issues.

I already have the thermostat delete. Is this fan setup available to purchase as a kit?

No, we never did put this together as a kit. We just use -8AN plumbing and a Derale 15870 cooler. I typically install them with a temp switch on the inlet, but with provision to manually turn the fan on via a dash-mounted switch. This is a heat shedding monster, especially when your'e dealing with limited airflow such, as when plowing snow.

Jon, if I ever decide to move up to Washington, I'll be sure to put these kits together and ship em out for you. Haha

Man has it all right. Thermoswitch pre cooler, with manual override, 8AN the whole system.

When you say delete the thermostat, are you talking about the one in the transmission cooler in the front?

Thought there was a "how to" on here I read many years ago.
