Whats the best performing value minded tranny cooler availabe for 727 tranny?

[1Bad70Charger]

Going to be running around next summer about 1200 miles on the streets/highway with a dynamic 9.5 converter in my 69 Roadrunner with its 727 torque flight and 3.90 gears (built 440 engine 525HP) and of course I am going to want to keep things as cool as possible.

Who offers the best valued tranny converter that works like a champ for more aggressive street set-ups and what can I expect to pay?

Also, running a full syn. tranny fluid will also keep things running cooler right?


Thanks in advance.

Yes I agree with Just 6T9 CHGR, I'm using the next size up it works great with my 10" 3600 stall, I also purchased a 9 1/2" stall witch I will run next spring and I'm sure it will be fine

Thank you gentleman, that is exactly what I was looking for and the price is right also!

Will the cooler be stand-alone or are you going to run through the radiator too?

[flyinlow]

I like the B&M plate cooler too.

In the old days, I  knew guys who got junkyard A/C condensers for coolers.

Not certain, what do you guys recommend for a hi-perf. street car that will get stuck in traffic in the summer every now and then?

I certainly don't want to make the car's radiator coolant run any hotter than it already will.

Will look to my engine and tranny's builder advice here but also want to see what you guys recommend.

I had an external cooler in mind and want to keep things simple.  The tranny cooler pictured and reference above is an external cooler, right?

Will be running a tranny pan that holds 2 quarts more than stock and will be running a full syn. tranny fluid to keep up with the heat.   Tranny is getting pretty much rebuilt also with high perf. spragues, etc.

I have run many coolers as stand alone units, never a problem. I like the B&M stacked plate unnit shown above and currently have it on the car.

That's all I need to hear thank you my friend!

I have mine plumbed as a stand alone unit

Geography plays a part in the selection, for Chigaco winters I would run through the radiator first. I agree that the B&M plate cooler is the way to go but size can be smaller if the radiator is in the circuit.

The car is in storage for the Chicago Winters and is now away for the season getting a high performance 440 build and will not be driven again until April.

Does that change your mind at all that it will not be fired up once this season in the cold weather (its in a heated garage for the winter)?

[John_Kunkel]

"My mind" says always run through the radiator if available but that's just me, lots of people run a stand-alone cooler. When doing so I would go as big as the real estate allows.

[flyinlow]

I have a large B&M plate cooler that I run stand alone with my a518 trans. The fluid temp is taken in the pan. Summer  temps 150* F on the road, 180* stuck in traffic. I drive the Charger in the winter if the roads are clear in Ohio (has the best heater of any car I own). Starting from a 40* garage it takes about 15 minutes before the the temp even starts to read 100* which is the bottom of gauge and never gets over about 140* on a 20* day. Not sure if the trans can be too cold. I use synthetic ATF4 fluid which I believe is the normal fluid for modern RWD mopar transmissions and should handle extreme heat and cold well . 

[John_Kunkel]

Not sure if the trans can be too cold.

Yes, it can, that's my argument for running through the radiator in cold climes.

Condensation inside the trans is more pronounced during the winter and if the trans doesn't attain enough temperature to cook off trapped moisture the moisture will pollute the fluid.

Do you run thru the cooler first?
