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.
