Technical Transmission Cooler

I have a leaking front radiator mounted transmission cooler that is blowing fluid all over the place. I want to relocate it to the frame rail near the transmission and have two choices so far for a replacement.
1. The B&M unit with a Sanchase case
2. The Heat sink double p*** aluminum unit.
I am running a 383 with a 700r4 and have never had any transmission leaking problems with the current set up until now. I also want to mount a front mounted pusher in front of the radiator to help with traffic cooling which necessitates moving the cooler.
I would appreciate any input you may have before tearing it apart.

The current transmission cooler is leaking through the radiator when running.

 

I would go with the double p*** alum cooler, lot less chance of getting a hole in it under the car. Gear head. $50.00

 

I have never felt the pusher fans did a lot of good, are you running an elec puller or a pump mounted fan? May need to go to a larger cfm puller if you have room. You are right thinking "hot in traffic, need more fan. Hot on highway, need more radiator"

 

Did you tighten the hose clamps?

(that's what causes mine to leak every few years)

 

Lynn--I use the aluminum ones--use two--one on each frame rail mounted with spacers for air flow--in series-seem to work fine.

I know the finned aluminum jobs are fairly popular, but I've never used them.
The ones from Earls are not the cheapest but their reputation is due to their HD design.
I have one on my 66 Suburban that is angle mounted on the frame in rubber biscuits, as well as a protective screen for debris deflection, gotta get a little creative on the early cars to keep exhaust heat isolated.

 

The cooler is leaking through the coils and being pulled through the radiator. The clamps don't leak.

 

Why not repair or replace what you have ?

 

Check out derale products.

 

I have used this double p*** type for several years now on my 39 equipped with Turbo 350 and 383 Chevy. I bolted it to the x member. Seems to work fine. I chose it because it looked like it would survive a stray rock or tire tread on occasion.So far it is trouble free.

 

very important, otherwise that "cool" looking unit is not doing a bit of good. post pic of what you are working on - what motor/trans? - why was cooler mounted the way it is now?

 

I use two like 39 guy showed in series-have done 10 40' this way--seem to work fine

 

Using any cooler that has real mounting points, instead of the plastic rods, will probably be a big help...

 

Pretty sure most people know this.
When using AN fittings like some coolers have, you are not locked in to using braided SS hose. Custom push-loc style hoses and fittings can look (in my opinion), HAMB friendly.

 

I run the alum double p*** on my 50 Merc and have never had a issue.

 

Anyone actually measure the temp differential between the inlet and outlet of those coolers to see how effective theyare?

 

I use the stack type coolers, they're stronger and more efficient. I have a Derale unit like this but haven't used it yet, all others I use in front of the radiator, have brackets I made (the push through zip tie tend to rub through).

 

I know that the inlet temp on my cooler setup is HOT to the touch and my temp gauge on the outlet barely reads 100° most of the time (outlet line a lot cooler to the touch). I went overkill on the panel truck since it's only running through the coolers.

 

I know it's not vintage.... But on my Avalanche I mounted this unit and it's been keeping the transmission fluid below 180degrees even in the summer heat when the truck is pulling a load. They say it's also suitable for mounting in low airflow locations.

 

I run a strait through like this. I have been told by several transmission guys that they are better than the double p***.

 

I highly highly recommend the extruded aluminum cooler. I have used this type for racing since the late 90's it works the best and can be hidden about anywhere.
