Testing the Derale trans cooler with 800 cfm fan

[DetailsUnlimited]

I will take pic of the final install and post up later. The cooler did very well after hard runs on the freeway and back roads. After 30 min's of hard driving I stopped and turned the fan on and Trans temps dropped 35 degrees in about 10 mins. When I go to the track and run back to back passes I will report on the results. Outside was 96. This was not at the track which the ground(asphalt) would be hotter.

like how you did yours... agree shroud blocks alot of the air when driving down the road..
heres how i did mine. i ran a temp switch 180* between the rad cooler and intlet side of the air cooler. then fuse hard wire to the bat with a led indicator light in the dash. only time it comes on is stop n go or slow speed where the TC isnt locked if its running when i stop i leve the truck idleing till the can shuts off

The cooler lines look kinda small, considering GM used 5/8 hard lines from the factory. That could restrict the flow. Are they 3/8--??

That truck doesn't have an Allison.
