Thread: Transmission cooler

Tweet

I have a new aluminum radiator that is for a straight drive but I am having a 700R4 built for my car, also installing AC so I will have to have the condenser in front of the radiator.
Question is has anyone ever used the round finned trans coolers that can be mounted to the chassic and if so how do you know that they are doing an adequate job cooling the trans fluid.
Thanks,
Wade

This subject was discussed on here a while ago, but you are relatively new and probably missed it. I am going to use one on my T, and my Son has one on his yet-to-be -fired up '29. So we have not tested ours yet. His is a double bypass unit, and I will buy the same one, probably this week at Daytona.

I had a lengthy discussion with the company that makes them last year at Daytona, before we bought my Sons, and I have every confidence these will do a great job.

Others on here will probably offer some better experiences with them.

if you're not drag racing or doing some heavy towing then it will work fine. a trans. temp. gauge looks good in the dash.

Don, thanks for your reply, what brand did you get, where did you order it from and how much do they cost, I want a good one, I am installing a 700R4 in a 62 Corvette?
Thanks,
Wade

Mike, thanks for your reply, I hope you are feeling better and you will have a hoppy Thanksgiving.
No I am not towing or drag racing, this is going in a 62 Corvette that I am building, just for cruising.
Again thanks,
Wade

Wade: Not sure of exact brand, it has been a year since we bought Dans, but I will sure know what one I buy this weekend, and will pass that along to you. Double pass has the additional benefit of both inlet and outlet on one side, as opposed to one on each end. I think it makes for a cleaner install, and supposedly they cool better.

I'll let you know.

As Don said, this topic has been hashed before.....we have an external fin cooler on a Jeep with a 700R4. We made it using extrusion that you can buy and cut to length:

The cooler replaced a B&M Super Cooler and apparently did an equivalent job. Make sure to mount the cooler away from heat sources (like exhaust pipes) and somewhere where there is air flow. Obviously, at rest, the no cooler has air passing over it unless there is a fan involved....that's why a radiator mounted cooler is preferred. In your case, stacking an evaporator, a radiator and a trans cooler in series would be hokey.....

Try the linear cooler, they're really cheap.

Just ordered a Derale cooler with an electric fan and thermostat to run in one of the Camaro's. Never have tried on, thought I would.

I've put a couple of the finned tubular one's on pickups, nobody has complained yet. Sure is nice to mount them on the frame and get some of the clutter out of the front. Got one for my '71, haven't fired it as of yet so I don't know whether they are worth a flip or not....

Mike at Tucson, do you own this company, if so could you make a round cooler by my dimensions when I get to the point that I am going to need one. The only place that I have to mount it, I think??? is on the side of the chassic but I will look to see if I have a place underneath the front of the car so that it can he hidden but also get air flow.
Thanks all,
Wade

If you don't mind, post the answer in this thread, I'm interested in the same thing.

I just asked my Kid what brand we bought for his, and he said it really wasn't any specific brand, just one of the many that are available from speedshops, etc. I couldn't remember, but the vendor we bought it from seemed knowledgable in cooling matters, and talked us into the double pass, where the fluid makes one pass through part of the cooler, and then takes a u turn and comes back the other way. The aluminum radiator I bought for my '39 Dodge truck is also a double pass, and the radiator manufacturer claims this aids in that cooling function too.

So, I guess I just find a good looking vendor booth at Daytona and pick up one that is about 24 inches long to fit across my frame, under my engine pulley.

Maybe the Jegs and Summit catalogs have some more info to help you guys make a decision on yours ?

Good luck,

Don

Guys for amy one that wants to know, look at www.derale.com and you can see all types of transmission coolers and it gives the distributors that sell them, one of them is Summit which is going to probably be the cheapest one.
Hope this helps,
Wade

This is a 24" double pass by Specialty Auto Tech. It's on a mild 5.0L SB Ford/C4.
I also had one on a hot 355W/C4 SBF several years ago - worked great.
