transmission oil cooler - factory?

https://www.gmpartsdirect.com/v-2008-buick-enclave--cx--3-6l-v6-gas/cooling-system--power-steering-oil-cooler

A power steering oil cooler that looks like it would fit behind the front bumper fairing on the Riv,  $70 from GMPD.  Look at the front bumper support in the pic.



Thoughts?

Should work fine, having a P/S overheating issue?

Not at all. I was thinking about using it as a transmission cooler, in the summer it'd help.

My opinion is it will be a bit small for it to do much for the trans.

Albert,
           If you have ever looked at a factory in radiator transmission cooler, you would realize what a joke they really are.  There is literally nothing to them, I think they have more value in bringing the temperature of the ATF up especially in the winter cold.

 I think it is an excellent idea to use that cooler in addition to the radiator cooler in series.  IMO, it will work great.

This is what I use on my 70 GS,

I'm sure it would work great in the Riv as well.

If it's still there Saturday I'll likely snag it.  A better idea might be one of the stacked plate coolers b/c they don't pass oil through all the cooling fins when cold due to viscosity.  BUT  I have not figured out where I could mount such a thing, in comparison mounting this one is kind of obvious.

And about the factory cooler, +1 that. A small heat exchanger in an end tank.

I bought and installed an external transmission cooler for my Riv 10 years ago and got an in-line thermostat from the same company.

I still have the trans cooler with all the paperwork. The thermostat I ended up using on my Harley engine oil cooler. Very well made unit and serviceable also.

I bought Tru-Cool Max trans cooler (Mini Max) and what they called a Remote External Thermal Bypass (thermostat)

I bought it all from Makco Distributing, Inc.
4255 Bryson Blvd.
Florence, AL 35630
Ph# 256-767-2839

With the extra fittings needed it all cost me $145.00 back in 2010
That included shipping and handling fees.

I removed the cooler and thermostat before getting rid of the car. Still have the cooler if your interested.
I'm sure I can find a box for the cooler to ship to you. Price will be right. just want to find someone that has a need.
I mounted it in front of the A/C condenser.
IIRC I ran it in series with the existing radiator cooler. That's why I ended up buying the extra fittings needed.
I know it would be easier to run it straight from the trans output and input. But that is also why I bought the thermostat for it.
Can't remember why I chose to run it in series with the radiator tank. ????? I'm somewhat brain dead these days.

Anyway, if your interested get a hold of me for any more info and you'll get it for a steal.

P/N 4920-1 for the cooler.

If you need more info PM me or email me as I'm not on the forum that often. I'm sure I can find a box to ship you the cooler if your interested.

You could plumb it ahead of the radiator to pre-cool the fluid then let the radiator bring the fluid up to op temp, or plumb it after the cooler to shave 30-some degrees off the fluid temp after it reached radiator temp. SO... I guess the question is, how did you plumb it in?

Does anyone have one on their 96 to 99 Riviera and if so does it work?

Thanks

Please elaborate.

RickW.. Do you still have trans-cooler available?
