4L80E TCM Identification

[4x4Junkie13]

After looking, analong and not finding, I contacted the Power Control Systems (PCS) manufacturer to get the exact info. The first letter denotes engine and the second denotes the production series by generation.
Listed as first A identifying Turbo or first B being N/A.

2100-AA: turbo first generation
2100-AB: turbo second generation
2100-AC: turbo latest generation

2100-BA: N/A first generation
2100-BB: N/A second generation
2100-BC: N/A latest generation

Hope this helps someone

Great info. Thanks for listing.

Any chance you got the spec for the shift points for the different models?

I highly doubt they would give that out but feel free to Google Power Control Systems and send them an email asking.
Maybe they will divulge.
I got the info I was looking for after rephrasing the question twice.

Great info, now i can change my transmission control with one of the spares. I have the 1123 but installed a turbo engine and never replaced the TCM. As is, it works ok but i have always felt it shifts kind of harsh. Also forth and torque converter are together.
