Transmission #2

The 1st one looks like a 440t4 or very early 4T60 not 4t60e. Being that it has integral passenger tail stock, I would say 440t4. Later 4t60 and 4T60e had removable tail stock. like the 4T65.
The 2nd looks like a TH125

I'd bet on a 4T60. I know I acquired one about 10 years ago for a planned swap out with a TH125, and it just got unburied in my shop this week.

Great, thanks!

Is there any way to tell which type of 4T60 (what the gear ratio is) by the stamped numbers?
