Just wodering if someone can help me with the proper trans tag code for a 70 chevelle ls6 turbo 400? any help would be great.

It should be a CY suffix.
The date assembled was stamped in the upper right,and the serial No. was stamped in the lower right.

my trans is a 1970 cb??

[Mr70]

What year is your CB trans. tag?
The CB suffix was used beginning in 1966 up to 1977 on many engine applications.
If it shows a 1970 production year,then it came behind a 1970 454 LS-4/345HP & LS-5/390HP Big Passenger series vehicle only.
