So I ordered das cooler from summit (Part number DER-13950) which is a large sized stacked plate cooler with a fan mounted to it for better cooling.

Image

It comes with all sorts of goodies for pluming and mounting but I don't really like the supplied mounting materials so i'm scratching that stuff. They also offer 3 different types of hose hook ups which I'll be using the barbed fittings for rubber hoses. It also comes with an electronic thermostat for automatic use. Here's how i'm going to plum it un using the supplied fittings and thermostat

Image

Image

And for those not electronically inclined, Here's how the wiring is going to go. There are many ways to do this but this is the way I like it.

Image

More to come as I get it in place and hooked up.

cool, I'm interested to see the improvement vs. the stock cooler.

I didn't really see any improvement from no cooler to the stock. It basically holds extra fluid. This i'm hoping will be night and day.

Have to love 3 day weekends!

I got pretty far and of course took a lot of pics. Here we go.


This is what I started with. The bracket on the left is one I made when I first installed my HF "off road" lights.

Image

Image

Image

It was in the way so it had to go. After that, I tried several times to get the tranny cooler in but the space wasn't there. I could either mount in somewhere else in the engine compartment or I had to "make" room. My AC hasn't worked since 2002 so I really didn't hesitate to much to pull out the condensor.

Image

Image

Image

Image

Now that there was a good amount of space, I needed to mount the cooler. I looked around to see what others had done and didn't like any of them. Luckily Iv'e been to Sims one too many times so I had plenty to work with.

Image

Pulled out the welder and welded this 3/16 plate to the center support.

Image

Image

Image

Now some Z shaped brackets for the other side.

Image

Image

And BAM!

Image

Image

Image

Ran the wiring through some split shielding and heat shrunk the butt-splices together.

Image

The wife was nice enough to come out and take pics of me for me.

Image

Ran the lines. The in-rad now hooks up to itself using the previous line. The order goes Tranny, cooler, filter and back to the tranny.

Image

All that's left is the wiring. In starting that I realized that what I had been doing worked but wasn't clean. I found a nice power distribution block which should help make it all look nice and more uniform.

Yay.

That looks great Rich, but now let me ask you this... Is that fan on the cooler a "pusher" or a "puller"? :goodfinger:

Looks good Rich. Is your temp gauge reading after the cooler? Id be interested in comparing numbers since mine is pre cooler.

I havn't driven it yet. I got back on it tonight after dinner. All the wiring is done accept for a 12V ignition on circuit. I'm not sure where to tap into yet. Any suggestions would be appriciated.

The fan can be wired either way but I preffer the fan be a puller and behind the cooler since it won't restrict the air flowing through when I am moving. Also looks better not having a bunch of fans showing behind your grill.

Before my tranny wouldn't stay stable enough to compare really. It would stay around 210 on my gauge but sometimes it wouldn't hit that at all and sometimes it would climb all willy nilly. I'm hoping this will steady it out. I'll let you know.

Go get a relay and power it from your stereo turn on wire. You already have stereo wiring right? that should be a breeze.

Post subject:  Re: Transmission cooler install (with pics)
that would mean yet another wire running into the cab. Everywhere I looked I saw people splicing into the trailer relay on the relay panel next to the air filter. I think i'm going to do that.

I've got so many now it doesn't bother me. I hid them in wire loom so it looks factory.

I would wire from the alternator wire (ignition on) so it will not come on while your in acc. listening to the radio. That is how I wired my fan and air compressor.

I was worried that it might have an up and down voltage effect. I'm not worried about it running while in ACC since I can turn them off if I want.

Thats strange that it fluctuates so much. I hardly ever run my fan on the street BTW, it just doesnt get that hot. Plus at 60+ on the freeway I dont know how much it helps if any.
