I'm trying to remove some of the Texas heat from my radiator which currently carries the A/C condenser (externally mounted in front), transmission fluid, engine coolant and electric fan (pull-through).
I've used different tranny coolers in the past but with all the new technology, it's hard to keep up (and I have limited space under the '34 roadster) - has anyone had some recent successful experience with a particular style (or brand) of transmission cooler that is relatively small and will really dissipate some heat? Any and all comments or info appreciated. Thanks.

I would suggest a fraim rail mount cooler. My father and I just put one on our 53 Bel Aire and it works great. We used a Jegs brand and it seems to work great.

Here this is what we used, easy to hook up and small. Good luck

Hey, thanks for the input - That was one of the options I was looking at for space reasons but wasn't sure how effective it would be due to the small volume. Glad yours is working well - and thanks for the Jegs link - I'll probably get one on order.

Glad I could be of some help Cooler works well for us, it is hooked up to a th400 behind a healthy 408 sbc.

I have one of the dual pass finned tubular ones from Specialy Auto Tech frame mounted and it works great.

I also recently used the Jegs frame mount on my 1925 Chevy with 700R4 works good.

The stack kind are better than the tube and fin.
Use the largest that will fit.
Use a thermostat, sold at Jegs, etc.

An auxillary fan on it will help a lot, if not be sure to put it in good airflow.

One thing that I learned in aerodynamics of a hot rod, is that the air isn't necessarily doing what you think it is doing. A frame mount could be in a dead air space when it looks like it is in a good place.

Okay, I really appreciate the input:
53 belair - thanks for the initial response and the link - 302/Z28 same comment and especially the link as it looks like the dual pass will provide some additional cooling (probably my first choice but a little pricey)
Not a T25 - thanks for the positive feedback
xntrik - I agree the stacked cooler would be more efficient but I run into a space problem and the frame mount sure helps. And I agree the air flow is not always what you think it is but I should be able to get it mounted somewhere with some clear space away from heat. With a little engineering I could probably install the stacked one in the rear (with a fan) which is what I did on my A/C condenser on a previous '32 Chevy sedan but that can be Plan B if necessary. B&M has a nice one that would probably fit that application. Again, thanks to all for the input. AWC

I've used these particular ones quite a bit and have been very happy with them.

I apologize that I was not clearer in my post.

When I referred to the "stack type" cooler I was referring to the construction of the cooler that is usually used for engine oil coolers, and indicating to avoid the less efficient tube and fin type. 100% of the surface of the stack type is exposed to the oil which is much more efficient than any tube and fin per dimensions.


www.jegs.com and clicking on transmissions, then B & M coolers, will show you the stack type.

Use a thermostat to control the minimum temperature.

Here is the cooler thermostat from Jegs.

Granted the stacked coolers are more efficient but if you use the tube finned cooler that is a double pass (inlet outlet on the same end) placed in a good position they are very acceptable, easy to install and fit in a tight spot nicely. I placed mine on the outside of the frame rail under the running board apron where the air from the fenders is directed past it.

xntrik, thanks for the follow-up. I had looked at the B&M cooler after you made your first reply and I think we all agree, they are more efficient and if I were building the car I could find a way to fit it in (maybe even build an airdam for cooling flow). For the present, I think I'll try the dual pass finned cooler on the frame rail - somewhere. It's not the best solution but it's an "80 %" solution. Thanks to all for your time and comments. AWC
