This is a pretty good article
http://www.metal-wear.com/racing.htm
Jerico Performance Products, Dyer's Top Rods, and Reed Cams are companies that have seen the benefits and provide treated parts to their customers
http://www.jericoperformance.com. They build NASCAR NHRA and Road Race manual or air-shifted transmission asseblies.

Who was your boss?
Cryoing has been done on 4l60/4l60e hard parts for at least 8 years on the high end builds.

i dont doubt for a minute that it DOES make it stronger- but I always understood wear resistance and reduction in distortion to be the key.
There was a formula SAE car that car a cryo block and it had a huge advantage until others caught on.
I always understood the strength increase to be present, but not too big.

A cryo-company slowly (about 1 degree per minute) cools a high carbon part to minus 300* with liquid nitrogen, leaves it for 12 hours, then slowly heats it back up. It rearranges the carbon molecules and makes the part 2-3 times stronger. Even works with carbon plastic! Cost is about 10% of the part. That's about $200-$300 for a tranny. I've heard of this but thought it was only for million dollar formula cars. Any of you other more money than brains racers tried this? If you know anything about it let me know. I'm gonna try it. I'll let the forum know how it works.
Call Bruce, he has some very nice hard parts for just about any application.

I'm looking at something other than the 4l80e for two reasons, first being weight, second is the inability to run a transbrake..

spelling sucks!
Cryo works well and makes a differance! I have had everything done from, gun parts, to axles, to motor internals, to transfercase parts and on and on!
Check out their site Deep Freeze Cryo They do lots of trans parts as well!

When a manufacturer gets heat treating/tempering, or cryo treating done they generally pay by the lot size. Its allot cheaper per part for someone who sends out 200 parts to get treated than a guy who just brings in a couple of shafts or parts to be done.
It cannot possibly cost trans builders $200.00-$300.00 dollars per trans to get this done.
I have handled secondary outside processes at many companies I've worked for and we never got hammered that high for a few parts, but we always waited if possible to send as much as we could to the heat treating facility.
Companies build relationships with outside processors, and the processore the same. The more you shine around the better deal you get to a point.
Its kind of the same for anodizing. Its a cost per lot thing.
