I am in the process of rebuild a 4r100 transmission. One thing I have seen on a few vendor sites is offers of parts being "cryo'd" . Having worked with Liquid nitrogen,oxygen before I looked into the process.
ATTN; It is not a dip!
I found that Nascar uses this process on any wear related parts. Many institutional fleets (police,taxi's) use cryo'd rotors and brake pads and JW uses it on some of his parts.
I might just try it on some planetary's and a shaft or two
You'all weigh in on this....
Cost doesn't seem to be that expensive, drop ship your goodies to them.
For the vast majority of applications it is a waste IMO. In high performance severe duty racing applications the slight edge may be noticeable. Basically the cryogenic process helps stress relieve the part.
