If I am seeing what I think I see, your spreader bar is your cooler. It surpises me that there is enough heat transfer area - did you use steel or copper/aluminum painted black. This is my cooler. You can also see the unfinished driveshaft loop - there because fuel and brake lines cross above the driveshaft, which, without protection is not a real good idea.

Correct that the spreader bar is the trans cooler . . . and license plate mount.

It's thin-wall - but not too thin - tubing powdered black.
Radiation area is 120 square inches.
Seems to work well, a lot of heat comes off it.

Black is the most efficient heat radiation color as well.

I have the same setup on the 31, but it has 100-110 square inches of radiation area due to it's smaller diameter.
The Derale 1" deeper with air tubes trans pan helps as well.

Your finned aluminum trans cooler looks to have quite a bit more radiation area than mine so you can probably expect it to work quite well.

Driveshaft loop be good.
I have two on the 31.
One up front like NHRA and SCTA rulebooks say and one toward the back due to a crossmember is required for the Chris Alston Chassis Works 4 links.
Both loops are Chris Alston ovals bent to a sharp radius from 1" x 2" rectangular tubing.

Pic = front loop.

Rear driveshaft loop.

Here's a recent pic of most of the chassis as viewed from the rear.

Here's a pic of the Derale air tube trans pan in my 32.

It is 1" deeper than stock.

No ground clearance problems as it hangs down the same amount as the engine oil pan.
