When I go back to auto, I will need a tranny cooler. The radiator now in the car has no provision for this. There are lots of them n the Summit catalog, and I guess they are all about the same. But where to mount one is something I could use advice on. I could put one in front of the AC condensor, but that is a stack 3 deep then. Will it still work if mounted on the frame? Can I mount it parallel to the frame rail and still get adequate cooling? If it needs to be up front I could open the intercooler hole back up and put it behind there. I would have to move the license plate back down then. (current photo is old). Thanks.

Sam

For a street car you have to walk the line between too small and too big. Especially in cooler weather you can run a trans too cold.

You also have to mount it where it will get good airflow yet not be damaged by road debris.

I would say get one slightly bigger than recommended since you are boosted, and put duct tape over part of it when it's cold out.

They are usually rated by GVW.

Thanks Dennis. I have read the new Ram trucks have a thermostatically controlled set of louvers in front of the trans cooler that open and close according to the trans oil temp. i would like to know what a good trans oil temp is. All the coolers listed in Summit are for vastly heavier cars than mine.

Sam- I have a complete Hayden Transaver Trans-Cooler part number 1402 set that I am not likely to use. The box says it is for "compact and mid-size cars, light towing to 2500 lbs., gross vehicle wight to 16,000 lbs." The size is 15 7/8" x 5" x 3/4". It is complete with the mounts and short hose length and fittings.

I can't remember what I bought this for but it has been on my shelf for years. It sounds like it would be just about right for your Dart. Interested?


P.S. F.Y.I.- the Hayden box says transmissions live best around 175 degrees oil temp.

175-195 is what I've always been told.

Too cold is hard on seals, too hot is also hard on seals and the converter.

Do they sell a temp sender for trans oil temp? Is there a pipe fitting that has a sensor and sender in it?

Sam

Yes, they do. Autometer sells the gauge and sender as well as a block that installs between the cooler line and the trans housing to mount the sender. Or you can weld a bung in the trans pan and put the sender there.

The GVW rating on aftermarket coolers are for use in addtion to the factory rad cooler. Since you dont have one,you'll need one with a much higher rating.

Thanks Charles. I was wondering about that. The one Reed is offering for sale is for 16,000 GVW. How does one figure this? It seems my car is nowhere close to that. Would this be adequate as a stand alone unit for a 3400 pound car? What would the GVW be for a Dart. That is payload plus curb weight, is it not?

I have an unused water temp gauge in the dash. I was going to use it to show the intake air temp with the turbo. Would this gauge work with the sender unit from the trans? If so, I will have to figure out which wire actually goes to it. At the time I ran it to one of the wires in the bulkhead connector, and then never used it. I would rather not pull the dash to figure this out.

So, What kind of signal should I put on a suspected wire to see if it responds? This is a typical autogage dashboard water temp gauge. I am hoping the only difference between the one that says trans and the one that says water is the writing on the front. Of course I am also hoping to figure out which wire goes to it.

Thanks as usual.

Sam

I went on line and found this guide to trans cooler application.

http://www.bulkpart.com/transmission-cooler.html

This sizing chart applies to installation in series with a stock radiator cooler. They suggest going up at least one size. So this looks like I would need a cooler sized for 18000 to 24000 GVW, since I do not have the radiator cooler in the system.

Reed, It looks like I will need to get something bigger than yours. Too bad, that would have been a good deal, and easy. Thanks anyway.

Rating a cooler by vehicle weight always seemed odd to me. I'd imagine trans fluid temp varies with much more then just weight of the car it's in. Plate style coolers are more efficient then the tube style. Those pans with the cooling tubes in them look nifty.

Sam I wouldn't just go "putting signals" on random wires to find the right one. Good way to blow fuses or other things. The sender doesn't really care what kind of fluid it's in, water gas oil etc as long as it can withstand the environment. The sender is a variable resistor that changes with temperature. If it's one of those solid sealed style sensors that doesn't expose the element, go for it. It'd have to be within the same temp range you want as well though. How many unused bulkhead wires do you have?
