Does anyone know the best location for a transmission cooler.I dont want to restrict the flow to the a/c condensor or the radiator as this may defeat the purpose.Did anyone verify temps before and after the install on both radiator and trans? (95 LT1)
Thanks for your input

If you don't hear from anyone, contact toptechx6. He just did it to his 93...

installed mine in front of the condensor,trans used to run at 200+ and now it wont get past 175 at 90+ degrees. my coolant temp did not change at all,177 -188 depending on the outside temps.204 with the ac on.

This how I did mine.

It's mounted off the front lower bracket and the radiator housing.
Works great!

it looks like you are running a 160 thermostat with modified fans-is that correct? I have a stock 180 stat I wonder how many degrees it would cool .My trans runs between is 200-225.my radiator temps are 194-198 (with dewitt rad) are you also using the radiator in series for cooling the transmission ?

The last place I wanted to mount a transmission cooler was in front of the radiator.
So, for my '92, I bought a second OEM power steering cooler and mounted it in front of the existing power steering cooler -- down low behind the radiator. This way, I didn't have to make any mounts.
Except for some short 2" sections of tubing to connect to the cooler, I used all hard lines.

My flow path is through the stock radiator transmission cooler and then through my added cooler.

I don't know how this would work for track racing, but here in Florida on 100+ degree days I have seen a max transmission temperature of 170* in stop-and-go traffic. When I get on the open road, it goes down to about 135* -- and this is with an ambient temperature of 100.

With this setup I don't dump any transmission heat in front of the radiator and I don't think I would want the transmission any cooler.

-----------------------------------------------------
By the way, when I bought my OEM power steering cooler from the dealership, they said the computer was showing about 10 of them left in the country, and then they would be gone/discontinued.

Jeez, it mounts in front of the condenser. If you radiator and cooling system are working properly, it won't make a bit of difference.

Will this supply less air to the power steering cooler?Will the power steering fluid be hotter-BTW impressive trans temps-are you running a 160 stat? Do you have any pix?-thanks

I converted my PS cooler to a trans cooler.

The PS cooler was a option on the Z51 cars;
intended to cool PS under heavy track work.Most street cars don't have one, so unless you are going auto-X you probably won't notice any difference in PS temps.
Even an aftermarket plate cooler fits/ works well in the PS cooler location.Plenty of airflow and safe from damage.

Actually, I don't know because that is the one area I don't have covered with a temperature gauge.
However, I don't believe, for my usage (no track use) that it will be a problem.

And, yes, I have a 160 thermostat (this is an LT1)

On my Honda Pilot and other vehicles that are not "bottom breathers", I do mount the additional cooler in front of the condenser.

But, for a C4, that has a problem with air-flow in traffic, I simply will not do it. To each there own, but that is my method.
I spent too much time making it run cool in traffic as it is to put additional heat-load and interfere with the air flow.

And, with the exception of the power steering, I have temperature gauges on everything.
These gauges show my method works for me.
With a 160* thermostat and a mildly modified LT1 in Florida on 100 degree days, here are my temps:
Coolant:
In traffic no higher than 198 (fans are programmed to come on at 195 rising and off at 185 falling)
On the open road, it cools down to about 181.
Oil:
Max temp in traffic about 221, open road about 214.
Transmission:
Max temp in traffic about 170, open road about 135.
Power steering:
Don't know.

Tom Piper,
Do you remember the trans temp before the cooler was installed? Any Pix ?.It looks like it is really working well for you. Thanks for the info

Tom Piper,
Was the Power Steering cooler an option or is it stock (I have a '92)? If my car has no PS cooler then that "space" would be open for the trans cooler? Thanks, Larry

Tom Piper

I didn't put a transmission temperature gauge in until after puttiing the additional cooler in place.
So, I really don't have any specs to go by.

Keep in mind, I've made some changes that keep the coolant cooler too.
So, the stock transmission cooler in the radiator is probably keeping the transmission fluid temperature lower when it gets to my second cooler.

I don't have any pictures, I'll try to find my wife's digital camera.

I think the power steering cooler was standard equipment on all '92 and up.

My second power steering cooler (the one I use for the transmission cooler) is mounted backwards against the original power steering cooler using the same mounting hardware.

yes, i have a 160 stat and my fans come on at 184 but i also have a 3 core rad.that is what made all the difference in the cooling temps not the thermostat.the tranny cooler is by itself only, i did not want to pick up any heat from the coolant so its straight to the trans.

Just to clarify I think the L98 cars only came with PS coolers with Z51.. However, the LT1 cars all have PS coolers (or at the very least my non-Z51 car does)..

Also the link provided earlier was a great link but for a L98 car which has different mount locations than your 1995 coupe does..

Here is a link to my install.. http://forums.corvetteforum.com/show....php?t=1808390

It is for a 1993 LT1 with a stroker 383 in Florida.. on 96* days with the A/C on full bvlast (60* and recirc) my engine runs about 185-195 omving and around 200-210 in stop and go.. My temps seem to be uneffected by the additional cooler.. which is huge (stacked plate B&M racing cooler 10"x11")

this is also with the stock radiator, 185* thermostat and the fans reprogrammed...
