Default what speed sensor do i need?

I have a bad transmission which i plan on replacing soon. i also do not have a working speedometer. i notice that many places list a speed sensor, and a transmission speed sensor. which do i need to buy? from the illustrations, they look like different parts. will a bad transmission speed sensor cause the computer to throw codes and not go in certain gears?

Are the places you're looking refering to a trans speed sensor and a wheel speed sensor? If your cluster doesn't work, I would be looking at the trans speed sensor and/or the wiring to it.

Speedometer is fed from the PCM but the PCM is fed from the VSS in the tail of the trans.

Not going into certain gears is mechanical; unrelated to VSS issues.
