True. It's a second to brake fluid as my least favorite automotive fluid.

I was doing a little research yesterday and saw that Oldsmobile offered a factory trans cooler on some W cars. I don't think the pre-bent lines will transfer over to a Pontiac because of the differences in core supports, but I think I'll follow this template for and install and bend my own lines. I think I can run them under the a/c drier and not have to drill any holes.

I run the biggest coolers I can fit, bend my own steel lines and hide the cooler up front where it can't be seen. The only clue is seeing one of the trans lines from the radiator disappearing under the core support and going to the front, and another line running to the back along the stock routing with the other line.
If done properly one really has to look at it and pay attention to even detect an extra cooler.

The Olds diagram you found gives you the idea. Modify as you see fit

Very cool! Heheh! I bet InLine Tube would bend those for you, they just did a deep resto on a W-43. But guess you already are going in another direction.

They do sell these lines pre-bent with a cooler, but the Olds core supports and front end structure are different enough that I don’t believe it would work on our cars. It’s also pretty expensive for what it is. There are much better coolers available for less. It did serve as a nice template for my install though.
