Trans cooler fan?

My trans is running a little warm on hot days or with the air on. I have a B&M supercooler but no fan on it. Is it very hard to wire one up? I'm thinking of putting this cooler on another car and buying a new one with the fan and thermostat.

Not very. You need the fan, fan relay, fan switch or thermo. activated switch and the wires. And maybe a fuse.
Most fuse boxes have spares, both Bat. and Ign. So you can pick up 12V from there, to the switch, to the relay, to ground. Or you can go from there to relay, to switch, to ground. This wiring can be lighter, say 16ga. or 18ga.
You can also pick up the 12V from the hot side of the relay, and go from there to the switch to ground. But this leaves your switch wire hot all the time. Also if you use this method your fan will run after you turn the ign. off. Same if you use the Bat. spare in the fuse box.
Then you have the other wire usually 14ga. or 12ga. that goes from the Bat., to relay, to fan, to ground. This wire needs to be fused as close to the Bat. as possible. You need to know the start up amps. for the right fuse size. If you only have running amps, you'll need to go up one size for the fuse.
Many fan kits will have all this in them.

I'm using the B&M cooler with fan the bigger one. I had to sacrifice the washer fluid bottle to have enough room to put it in front of the a/c condenser. I have yet to have the fan come on though. Trans runs around 150-160. I have a deep pan from Deral with cooling tubes and I am using 3/8" cooler lines instead of stock 5/16". Also I don't have the cooler in the rad.

Z-RATED94,
This brings up an interesting point. How do you know your trans. is running warm? Do you have a temp. gage on it.
I would suggest that 150*-160* is to cold. I like to see oil in the 215* to 220* range, and synthetics can go even higher.

I have a trans temp gauge that reads 180-185 until the air is turned on, then it goes to 210. I personally like the 180 temp better.

Don't understand why you think this is a problem. Stock LT water temps. are higher than this.

most trans temp gauges show 210 on the well over the half way mark. Id say if it is sitting above 180 consistently Id find a way to cool it better.

If im on the highway for an extended period of time, it never gets above 165*, why would you think that would be too cold? Heat is the number one killer of transmissions...

You can get a fan from Jegs, Summit, Flex-a-lite,or Perma Cool to name a few. It will come with install/wiring hook-up directions. I used an 6" from Flex-a-lite on my trans cooler and it works great.

Not mine, 185 at most. Rick

true that... mine doesnt cross the half way point ever.

Funny most of the gages I've seen usually run from 100* to 250* with 180* being straight up. That hardly puts 210* well over the half way mark!
I still maintain that temps. of 150*-160* at normal hiway speeds are a bit on the cool side. Perhaps "to cold" was over stating my case. And I suppose I should clayify, the 215*-220* would be peak performance numbers, not daily driving.
In any case Z-RATED94 is well within the operating temperature parameters of trans oil.

Oh, I did have one other question. If you have a remote cooler, why does turning your A/C on affect it??

Condenser heat? You tell me, I'm open for ideas. ;)

I quess the next obvious question is, where do you have the trans. cooler mounted. One thing that happens when you turn your A/C on is that the rad. fans come on. Maybe the trans. cooler is getting hot air from these fans directed at it??

It's located on the passenger side above the air dam in front of the rad. (more or less) It might not be in a position to have the fans draw any air through it.

Thanks Fred, and to everyone else too. If anyone else has pics of their set-ups please post them. I'm sill trying to decide the best spot to help the fan do its job.
