08 v6 trans cooler question

[Marv D]

I bought a 08 last year with the 4.3 V6 / 4L60/ VERY basic truck (even crank up windows and manual door locks) AC and a nice factory sat radio is about the only creature comfort it has.

The thing only has 47,000 miles (no typo, ONLY 47k) is super clean, straight, and runs / drives like a new.
I added a Edge CTS to monitor all the stuff the dash doesnt have
One thing that IS available in the DIC is "Trans Temp" Well with the Edge monitor I am seeing hot Arizona summer days (110° ambient) , on the freeway at 80 the trans temp climbs to 218°
Engine is nice and cool at 198 but the trans keeps climbing

So I look and there is NO TRANS COOLER in front of the condenser.

I do NOT want to chance the typical 'universal' coolers with the 'cut a tube and hope like hell the worm-drive clamps holds'

I looked at Mishimoto and a AC Delco and few other but can not find anything that says will 'add' a cooler where there once was none! Everything seems to me a 'replacment' for a factory cooler. Hell I'd be happy to buy a used GM and the factory steel lines. IF I COULD FIND IT.


Anyone have an good ideas? It's gutless with the 4.3 and I don't tow anything, but over 210° trans oil has GOT TO CHANGE
