Tru-Cool 40k trans cooler remote install with dual electric fans

[ndopita]

Hello all,

Just wanted to share my installation of a Tru-Cool 40k on my pickup. Truck is a '69 C10 longbed with a turbo'd 5.3 and 4l80e. I was previously running the radiator cooler along with a decent size tube and fin cooler up front. I was never able to control the transmission temp with this setup so I decided to start fresh and remote mount a standalone tru-cool under the bed with dual electric fans.

I have been running this setup for almost a year now with nothing but awesome results. I was even able to hot-lap it with no issues at an 1/8 mile heads up no-prep event on a 100+ degree afternoon and keep the trans under 170 degrees easily. It also has no issues sitting in traffic with zero airflow. The Holley kicks the fans on at 150 degrees and they will cool the trans down to 140 and shut the fans off in a matter of minutes, especially cruising with the converter locked.

Here are the parts I used:

Tru-Cool 40K - tons of vendors on ebay: https://www.ebay.com/sch/i.html?_fro...l+40k&_sacat=0

Dual Fan Shroud - https://www.ebay.com/usr/kan-madeproducts

Fans - https://www.americanvolt.com/collect...66aa8023&_ss=c

Installation was no big deal at all. I bent up some simple angle brackets out of some leftover 14 gauge steel. The brackets bolt to the supports under the bed and space the top of the cooler down about 1" under the supports. The shroud bolts right up to the cooler using the bolts that come with the cooler. A little drilling is required to bolt the fans to the shroud, but you just center the fans on the holes in the shroud and drill out where you need to bolt through. I just used barb fittings and transmission hose to save some money but you could also us AN or hardlines just as easily. I ran both fans on a single relay that is triggered by the Holley.

I will post photos of it all below. Thanks for reading!
