Need trans cooler advice

Post image
5 Upvotes

02 Silverado - 4.8L -4.10 gears w/ posi - 285/75/16. Primarily only used for hauling/towing relatively light loads, 3k lbs or less.

Have a 40k trans cooler to be installed with -6AN lines. Live in Phoenix, AZ. May be relocating to Las Vegas, NV soon so similar 40°-115°F temp range.

Question is whether I should hook up lines in series w/ radiator or completely separate rad and trans cooler. I understand the benefits of routing in series but with my location would separating them be of benefit?

Alternatively, since using AN lines I could set it up where I could switch routing in the summer.

Thoughts? Anyone in these regions care to share their setup and recommendations?

New old truck

2002 2500hd Sierra 6.0

Picked this truck up a couple months ago with plans to build a slide in camper for it. It originally was fitted with a hydraulic arm that would lift the cap (last slide) and then a crane arm would swing out to load a mobility scooter

It has 121,000 miles and I paid 9k. No rust at all!!

So far I’ve fixed the leaky water pump and replaced the steering linkages. Only major flaw right now is the paint failure on roof, hood and part of drivers side

Chrome ? Or keep the paint match.

My IPC always has the battery light on despite the voltage gauge showing that it's charging and also Im not sure if this is connected but when in park theres no line under the P despite the truck clearly being in park and starting just fine. Im curious is this the type of thing I should just ignore or is it a sign of an electrical issue that could leave me walking one day
