Other transmission Cooler options
Now for those that are wanting to install a transmission cooler but don’t want to go through as much trouble like I did for this there’s a cheaper and easier way. Now keep in mind you will not see the same cooling results with this option as I am with this set up. The following option is what I did have before I installed this cooler and I never saw above 200 degrees F which is good. And that was only about a 15-20 degree difference from stock.
This is a link for the coolers I had before. I had two of them installed and never got above 200 as I said a second ago

The way you want to install coolers like these is to find the line that is the return line from radiator to the transmission. On grand prix’s that line is the one that is the bottom on line on the radiator. it is also the shortest of the two lines on em as well.
This is both the outlet and inlet lines for the stock cooler. (Keep in mind the only reason that both of mine are cut like that was so I could easily remove the old lines from the car instead of trying to wiggle them out)
The line that is the longest is the one that goes to the top of the radiator and the shortest one is the return line back to the transmission.
You have to installation options.

And the way that one works is you remove the stock fitting from the radiator on the bottom and install the thing I listed in the link right above this and put the rubber hose directly onto that with a hose clamp. You want the rubber hose that runs to the new cooler to be the one you install here. You also want to keep the part of the transmission line that comes from the tranny… could just use a little jig saw and cut it leaving a few inches at the transmission and slide the rubber hose that runs from the coolers to the tranny over it and secure it on there with a hose clamp or two as well.
And the other way which I recommend doing will require one of these

And you will want the 3/8 barbed one. They also sell them at local auto parts stores but I gave up trying to find a link at one.
Picture of both of the stock lines. The one we are referring to right now is the shortest one.
The center rubber section of the shortest one you want to cut. You can do it from the bottom of the car by removing the splash guard crap that is hiding it. Once you cut it. The end that is running from the radiator you want to use one of those barbed fitting and put it there with one running to the new coolers. Then the other part of the stock line you want to put the other barbed fitting with the line running from the new aftermarket cooler back to the transmission.
So basically with either of those setups you have all the coolers running in the following order
- Transmission to stock radiator
- Stock Radiator to Aftermarket cooler
- Aftermarket cooler back to the transmission
So some things others do is install an extra filter inline with the cooler to help take contaminants out of the fluid.
This filter can be found here

and for some other stuff. This filter is 91parkave’s new filter for his transmission and it’s a much better upgrade from what he did have. Higher flow rates and filter is decently bigger
