transmission build dates?

[grumpyvette]

Ive recently got my hands on a couple different transmission cores, that I was given in a trade for a few engine parts I no longer needed, and while I clean them up and look for numbers and inspect them for damage etc. I would like to find out what they came from, now I know they are ( 2-4l80e) and (2 -700r4)
and I was curious if theres an easy way to find the date they were built

AS I FIND LINKS OR INFO I WILL POST THEM IN THIS THREAD FOR FUTURE REFERENCE
yes I,M aware this holds true for some but its not obviously true for all transmissions

[Strictly Attitude]

build dates on the 700r4 are important there were allot of changes in design over the years on them. The older input drums held less clutchs and had a smaller 28 spline shaft. Other changes also but you can do some upgrading to them.

 

[grumpyvette]

its also true on the 4l80e as the transmissions built ABOUT PRE-2000 have several less upgrades than those built POST 2000
Ill freely admit "I'm not a trans guy," but I have a few friends with impressive cars, (some of which I built engines for) pushing over 600hp, some with over 900hp and the 4l80e trans has developed a good reputation for durability
