The transmission cooler built into my radiator is not cooling enough. I have an a/c condenser in front of my radiator. I'm looking for suggestions on which type of cooler to get and where to put it.

Bruce....I mounted one to the passenger side of the radiator behind the grill. It was about 8" x 12" if I remember right. Made a bracket to hold it and ran the lines. Worked well for me.

Here’s where I put mine. Just a couple of simple sheet metal brackets to attached it to the hood latch support and the valance panel.

To avoid air pockets remember to run the line that feeds the cooler on the bottom and return line on the top

I run a stand alone B&M stacked plate trans cooler (on a 2004R Trans with 2800 stall converter).
I have read that the stacked plate coolers are more efficient then the tub & fin design. I also mounted the trans coolers so the feed line was connected to the bottom off the cooler and the return line was connected at the top.

I never liked the idea of having a trans cooler line that was also connected to an internal radiator cooler... due to the problems that would occur if the trans cooler within the radiator was to ever develop a leak (coolant would mix with trans fluid 😫). I run my trans cooler as a "stand alone" unit.

I do not have a trans fluid temp gauge, so I just installed the largest B&M trans cooler that was available (B&M 70274). I have never had a problem.
B&M SuperCooler Oil Coolers 70274

If you decide to go with a stacked plate cooler and want to save some money, B&M Super Coolers are reboxed Tru Cool coolers (both brands are made by Dana Corporation in Mexico). Tru Cool coolers are 40-50% cheaper and are lifetime warranty. B&M one year warranty.
I also found a Tru-Cool H7B Trans Cooler at Amazon for a lot less $$$ than a similar B&M trans cooler.
Amazon.com: Tru-Cool H7B ENGINE OIL COOLER: Automotive
The Tru-Cool H7B cooler looks exactly like my B&M 70274 cooler.

Whatever cooler you decide to go with, be sure to mount the cooler in an area with good air flow.

Thanks for the great ideas. The one RifRaf has looks like it would cool about anything but I am not sure I could get one that big in front of my a/c condenser. I like 74lsnova's idea of mounting it to the hood latch. Did you only mount it on one side? If so what keeps it from flopping around?

I just happen to have my front end off to swap the fenders so it’s not complete. If you look on the left side of the cooler there is a little tab that bolts to the metal panel under the plastic valance behind the bumper. Once it’s all
Back together it’s rock solid and doesn’t touch anything

Here’s a better shot of the second mounting point.
I see how you made the bracket but I can't figure out what you bolted it to. My car is a 68 and yours is a 74. I know the bumpers are quit a bit different. What are the dimensions of the cooler you used?

I will have to get the dimensions. I have a 68 nose on the car so they are exactly the same. The painted valance between the bumper and grill has a metal panel under the plastic valance. It bolts to that.

The total dimensions of the cooler are roughly 11x6 including mounting flanges.

Here is how I mounted mine. It runs in series with the radiator's internal cooler.


I don't have a temp gauge for my transmission so no way to know how well it's working.

Thanks guys with all these suggestions I should have no problem fitting one up front. Now I just need to save up for the burned up transmission I’m dealing with.

If it was me... I would still mount the trans cooler with the inlet trans fluid line at the bottom and the return trans fluid line at the top.
