Takes $ to plumb in an oil cooler.
$300-$700 cash.

????? That much? What would you install? I have the combination cooler in my 84 T/A.
Engine oil and transmission fluid mounted in front of the radiator. That and the hoses.
What else? Unless you are thinking of using braided stainless hoses.
 
Yes Braided Hoses & AN Race fittings.
I would only use Teflon Lined Hoses.
#10 AN.
Adds up $$$.
 
Yes, the $$$ sure does, especially with AN fittings. And you must get the
Endura plated type because the anodized aluminum ones corrode after a while.
The "ice melter" being used on the roads now eats these also.

Oh yeah, then there is the oil filter adapter to make your connections.
While we are on the subject, what are your thoughts on the placement of the
auxiliary transmission cooler, example - out of trans, to radiator cooler, out to
aux cooler, back to trans? Or out of trans, to aux cooler, out to radiator cooler,
and back to trans?
The first example would further cool the fluid after the radiator cooler. Good for
summer. The second example would cool the fluid first through the aux cooler, and
then either cool more through the radiator cooler, or warm the fluid before going back
to the transmission if it were really cold outside - winter.
I know that thermostats are made for doing this, but I am NOT using one because it would
get really complicated with the hose routing, and I don't have much room to begin with.

Since You and I both have cold weather to contend with 40 F down to -20 F & even -30 F in our Lifetimes East coast & Midwest....I would use the radiator trans cooler also Mike.
I like the idea of Auxiliary Trans cooler plumbed for the Return side back to trans.

The Trans Cooler I want for my 1963 G.P. is made by MOROSO.
Made for Drag Racing but I have used it for others.
Can use it as a stand alone.'
1 st time I had seen it was on my Bud Ed's 5.0 Mustang back in 2001-02.'
10 -second ET then, few years later 8's.
MOROSO Trans Cooler always did the job.
Its unlike any other trans cooler out there.
Heat sink fins & integral filter cartridge easily replaced.
$200 only.....But i want it.
 


I still like this Grumpy....4L80E installed Dirt Cheap.
No Computer .
Light Swiches. Cost is Free . Almost .

Grumpy, your opinion on this, if you please.
 
http://garage.grumpysperformance.co...sion-and-oil-cooler-increases-durability.176/
think about it a bit, the ideal trans coolant temp should be in the 150F-160F range, so how you route the trans fluid cooler lines maters, engine coolant can easily run 210F-230F going into the top of the radiator, from a hot engine and run 170F-180F returning too the engine after its trip through the radiator, thats more likely to heat than cool transmission fluid.
having an aux trans cooler with an electric powered fan and AN#8 minimum line size is generally a very good idea!(obviously you need to have the clearance and location to mount it

Thanks for the diagram. I forgot that I already have a remote transmission filter already.
And the routing of the hoses for a remote oil thermostat is not as complex as I thought.
Any recommendations on brands for thermostat?
 
Old Habits Die Hard Grumpy.
A Free for all like Digital Corvette in the old days.
All the New Guys came from other Forums.
Must have been Similar.
 
Looking at used Pontiac 9.3 Highwsy gears.
3.08 is the tallest 9.3 gear I have right now.
Still in an Original 1957 Olds 9.3 rear I have.
Like to leave that Rear Differential intact.
Its a Favorite for Nostalgia Gasser Racers.
Narrowest track factory 9.3 made.
 
Different options to crusie 100+ Mph to Chicago and back in my 1963 Grand Prix.
Have another Factory 9.3 Posi Rear Hogs head 3rd member. 5.38 :1 gearset on it.

Thanks for the recommendation. So simple and only $44.00. I'm getting one.

So in this diagram, I will be using BOTH the cooler in the radiator and the auxiliary cooler.
Where would you insert the radiator oil cooler?
I'm thinking between the filter and transmission out. The metal line coming from the
transmission would connect to the lower radiator fitting (like stock) and out the top
to the remote filter. That way, it operates like stock, and if the thermostat should
open, then it will have additional cooling through the AUX cooler.

love the modified diagram, but I think it will confuse many people
trans fluid goes through most radiators not hot engine oil,
and the same diagram with a transmission in place of the engine would be better

I cut the 3rd K&N HP 2003 Oil Filter open at work here about 1hour ago Grumpy.
Very little debris.
No metal, Bearing Babbit, or sparkles in the Sunlight.
4 Th oil change I did Saturday .
Good to go .
These Olds 425's must have been built with GM Moraine 400 bearings and Blueprinted like Joe Mondello ssid in an interview done by Engine Builders Magazine back.in 2008 that I read prior.

Thinking about the Trans Am 455 RAIV now Grumpy.
That Tall Deck 427 Big Block Chevy I have too.

You're right, I didn't catch that. My cooler is a combo - both engine oil and trans cooler in one plate.
I'll work on modifying the drawing so we can use it correctly in the future.

The Speedometer cable broke in the 1963 Grand Prix driving home from work Grumpy.
It lasted 53 years.
Found another replacement .
They are 72" inches long the Whip speedo cable in my car.
Used my Garmin, Reads MPH Via Sattelite.
Also rode by 2 State 5.0 talking to each other.
Still No Exhaust .
Open Exhaust Manifolds.
 
OK. It took a few hours, but here it is:

And here is your standard setup with just an AUX cooler added:
