To ID the transmission look at the pan.


If it came from a 73 Delta 88 chances are it's a TH 350 or TH 400.

more than likely that is the die used when the case was cast at the foundry.

I work in a Big 3 transmission assembly/aluminum casting plant, every part cast has an identify letter/number cast into it. That make finding suspect parts much easier to find if there is a die issue.
