It looks like another 4L60? Is there any difference between the two other than the TC? What stall speed on the TC?

Thanks guys.

Transmission is more or less the same. I think technically the first one was a 4L60/4L65 and this is a 4L70, both were rebuilt with upgrades. Cosmetically they are identical, the main difference is the addition of an input speed sensor and all the associated parts to add it. Torque Converter is an aftermarket 11 inch, stock is 12. I think stall was advertised 2400-2600. Im not sure where it actually ended up but its a noticeable difference without being overly aggressive or annoying on a light cruise.
