I decided to upgrade my 64 Plymouth Fury convertible.I installed a 440 engine and a Cope pushbutton 727 trans.I thought I made a wise choice with TTI headers but the trans lines are going to interfere no matter what.I called John Cope and he said to get an external oil cooler and run braided lines along the driver's side fender.Sounds good I think.Is this wise do you think to put the oil cooler in front of the Griffin radiator with two puller fans on it.Am I cooling the trans at the expense of the engine running hotter.Eventually the car is going to end up in Arizona where I can enjoy it year rond instead of the 3 months I get in Conn.Thanks
 
Are going to series in the line with the radiator? Or just use the cooler by itself?
 
I like some of the newer ones with the fan attached.You could mount it over the rear diff of in the fender well:blob1:
 
I don't think mounting it in front of the rad will effect cooling at all. I have mine mounted like that. Just get like 8 x 14 trans cooler. Pulls air through it and the rad. Just my 2 cents
 
The factory HEMI cars had an extra cooler in series with the one in the radiator so I wouldn't worry about mounting your cooler out front.
 
Thanks

At this point I don't know the best thing to do.I really appreciate all of the advice I'm getting.CRT says I don't need to use the radiator only the auxillary oil cooler.If the cooler mounted in front of the rad doesn't affect the cooling that might be the best way to go

Just let me say you have an awesome car and I always find your replies usefull and informative.Maybe we'll meet someday(I'm in Conn.)I'm letting your idea rattle around in my pea brain.I have powermaster working on making an internal fan 140 amp alternator for Chrysler products that will actually fit unlike their GM design that they market for Chrysler products.I don't know if electrically the 140 amps is enough to run my two puller fans plus an additional cooler fan
 
Sounds good

Do you know of any picteures or sketches of how this was done.I'm a good copier but my imagination skills have eroded over time.My TTI headers make a factory routing difficult plus my push button cable makes it a congested area
 
If you run just a cooler for the trans with out going through the radiator you are relying on air or a fan if you have room to cool the trans fluid. Most every set up series in the radiator this way you get cooling for sure and have the benefit of extra cooling. I would be skeptical of using just a cooler trans get hot just like your motor and need to have cooled fluid run through them.
 
Unless I had a strictly strip car, I wouldn't dream of just using the small trans cooler!
I think they should be used in series with the radiator so it's "Auxilary" "Extra" "Additional" cooling..... After all,,, this is usualy the reason they get purchased,,, because we need extra cooling. It's not to suggest that the device on its own is "Extra" compared to the stock cooler, but becomes extra in additon to the stock cooler.

My 2 cents,
 
Using just a cooler will work if it's big enough and having a temp gauge is always a good idea no matter what you are using but on a another note, if you do any driving in cold weather, the fluid should also run through the radiator cooler to help heat it up. Just like motor oil, trans fluid works best at normal operating temps so if you do run an aux cooler, run your flow through the aux first then to the radiator.
 
When I was running a 727 in my Coronet, I had a TA 3800 convertor and was concerned about the extra heat that it would produce. I installed an air conditioning condensor in front of the radiator, using it as my only source of trans cooling. My stock big block 4 speed radiator had no automatic trans provisions. I used a steel 5 blade fan and shroud. The stroker engine never got hot and the trans temp gage (plumbed into the trans pan) never got over 200*. I ran stock type steel lines as the factory did along the block/oil pan mating surface. No fuss. No muss.

In my humble opinion, I agree with Cranky that the trans fluid should be routed through the radiator in any street application. The transmission and fluid have been engineered to work at an optimum operating temp. The stock system maintains this temp. If modifications such as a high stall converter and increased horsepower have been made, then a cooler ahead of the radiator is a good idea. If it's a racing application, then that's a whole different story.
 
Thanks for all of the replies-I greatly appreciate all of the feedback.I'm thinking of using the oil cooler and the radiator oil cooler in series as suggested.Now that the hard part is done (the planning) I'll be ordering more parts on Mon.

I use a "C" body radiator that's been recored with the high cooling capacity 3 row nascar style fins.Aluminum water pump & mopar water pump.The dual fan is out of a late 90's V8 Camaro/firebird that was a puller and I reversed the polarity to make them pushers with a separate relay & switch for each fan.The trans cooler is of the huge family w/o any add'l fan.The alternator I've been using for over 10 years is a 100 amp 1 wire large style GM unit.When I'm cruzin with the fans on,I never see the system pull more than 40/50 amps and on a 90* day sitting in bumper to bumper traffic the temp does not go over 200* and will fall back to 180 to 190* depending on the conditions.I don't disagree with any opinions as far as flowing trans fluid through the rad or not,I just never did:head_smack:

X2 and i am an old truck driver. X2 on the temp gauge.
 
Thanks for the pics.

Like I said before your car is awesome
 
I have a separate trans cooler that I mounted a 900cfm fan to and it works great. This is a street car with a monster stall and everything stays cool in the heat of the day.
 
I love all the different input on this forum. Everyone has some awesome applications that work well. So let me throw another cog in it. Aluminum rad with no tranny cooler attached. So I have to run a seperate cooler. Im assuming to bring cooler quickly up to temp it should be near or infront of rad. Definately a gauge to check temp would be a good way to go. If needed a fan maybe needed to be attached.
