Whats it look like where you hooked it to the radiator cooler?
Glenn’s Auto Performance recommended bypassing the radiator completely, so it’s just straight back to the transmission. The kit was pricey but I had it installed in about 40 minutes and I’ve had zero leaks since installation.

I want to keep the stock cooler.

Most of my engine parts came from that guy. My brother is/was a dealer or something for him.

Thanks to the kindness of @Geotrash I'm digging in on how the best way to go about installing it since mine didn't come with the external cooler and I replaced the lines with new GM when I had the engine and trans out.

I was just tinkering with my OEM transmission cooler lines.
a -6an tube nut and sleeve was a perfect fit.
A little hard to flare, I had to really crank down the 37 degree flaring tool

I might suggest stainless or steel sleeves and nuts in order to get a good clamp on the flare.

I just had this up, I was thinking ideas about how I'm going to route my cooling.

Now I'm thinking I'll split the fluid at the line filter.
then run one end straight to the external cooler, and have a valve to control flow (winter).

Then for the radiator side, retain mostly stock...
then that turned into "maybe keep some of my original lines" etc.

if you want keep it running thru the radiator then you just need 1 extra line and then the adapters needed.
1. enters the radiator from transmission
1. exit's the radiator and flows to external cooler
1. exits the external cooler and returns to transmission
or it could be reverse, either way you just need 1 extra line.

You’re welcome. I’m always happy to help people spend money. :cool: But I was right, huh? It’s almost a joy to bleed brakes with one.
If I'm honest, nothing is fun in regards to to under the car on a lowered vehicle haha. But damn if this ain't the best thing since sliced bread. a huge thanks, again.

Hey, I want to join in on the Tru cool 40k kids club! Mine has been installed in this location for 2 years!

So both Powerstop and the vendor I bought from need a few days to look into if they can get me a proper replacement or not on the caliper. U know, items can't be returned or exchanged if they are used...(anger).

To add to this $hit sundae, when doing the front brakes I noticed the cv boot had a hole in it and ALL the grease was out. There's another $400, because f doing that myself.

Axles aren't that hard to do yourself. Save yourself some money and do them in your driveway.

Sorry about your issues with the Powerstop stuff. That sucks :(

I can tell y'all first-hand that you DO want the radiator's fluid cooler IN the circuit BEFORE the external cooler. I've run it with and without and the temps were out of control without it in the circuit when towing over the mountains in the summer. The water-to-oil cooler in the radiator does a great job of warming the fluid when it's cold and taking the heat out of it when it's hot. The GM upfitters manual also makes the same recommendation.

Like Jacob said, those front axles are pretty easy. I think I had to take the strut off and then the bolts holding the axle on. I cheaped out and bought them from advance auto instead of the gm units. From what I could tell, basically all aftermarket axles are the same and with the parts store house brand, lifetime warranty and I don't have to deal with shipping and wait times if I have an issue. I did both sides in an afternoon
