Yah wanted a Tremac very badly.

After careful inspection of the OLD Derale units I have and the expensive cooler I bought, the unit I bought is the more expesive style 40 stack. The cooler they are installing into the fabricated units with fans, is DIFFERENT quality and a lot more money.

The NEWER supposedly HQ coolers look as if they have been substituted with a cheaper manufacturing process, zig-zag fins, which IS exactly the same side tanks and weaker brazing as the PKSABB.

Nasty-LSX is correct in his video, when you compare the lower grade newer units and the supposedly higher end stacked plate versions. They all sx now.
The old style units did not have any zig-zag fins. They were brazed tubes with a ripple effect to increase the tubing stack area, roll formed and sealed with brazing and a series of clips at each end of the stacks.

It's disgusting at how many aftermarket companies are selling one picture using a reputation for high quality and then you open the box, find out you are buying the low quality crap instead.

Suppose a can of Cooler Clean or Cooler Flush and a couple of OEM coolers, stacked and mounted back to back, with custom -6AN fittings between them, might have been a better deal in the long run.

All the transmission shops threaten to void the warantee, after the sale, if you do not replace the cooler with a new one. Perhapse they need to take a seroious look at offering re-manufactured coolers as an option and force the yards to stop scrapping all the valuable OEM high quality parts for a change?

What a racket.

I mounted a derale with a fan under the bed right behind the cab.

You can still get quality stacked plate coolers. I have a tru-cool 40k on my 2011 Burb and it stays no more than 70 degrees above ambient... no matter what I'm doing to it.

I'll probably run an H7B or M7B on the square for the 4L80.

This is what I did but with the Jegs 30,000 GVW unit with fan. I ran 6an lines and used a Mishimoto temp sensor to one of their relays.

Agree with both of you, and your solutions.
https://www.amazon.com/dp/B072C63CG9/

Zig-zag fins, not 40 row, and not the same as the unit I bought.
It's actually half the unit for the same unit I bought, with a scetchy thermostat unit to supposedly protect the transmission>

WTF, over?

My point was it's not getting any easier to find a quality solution, for the new guys. Glad you both posted so others might stand a chance!

My OEM fan was a bust so the:

SPAL 30101522 12" Fan Puller Curved Blades​

...is on the way and the OEM PUSHER will be added to the front as a spare/alternate fan as a back up.

Without radiator cooling for the 4L80E, with respect to the failure rate of the best in class, I'm adding the OEM fan (without bending the surround this time, as happened in my original ghetto mount), and using it as a back up pusher.
All on a switch, not the failure prone sensors that plague the world.

Darn shame.

Carling 20 amp switches actually hold 20 amps? Who'd have guessed it?
40 amp Relays near the power source with breakers, protect the switches mean time between failure rate.

IDC if they have an RFID Tracker for MilSpec, they are required to meet the task without failure.

Enough of the B/S crap with being forced to buy sub-standard under threat of trackers.

In my slightly "bent" mind:
Build it right, or get stripped from the market for gross negligence and planned obsolescence!

The US economy, strong enough for the average guy to go buy quality controls, motors, tools and wiring from Grainger, has been ruined for a long time.

This Horse manure needs to stop.
