Disconnected speedo cause no Overdrive?

I have an 82 supra auto with a digital dash

recently did a transmission swap and while i was hookinng up the cable, i must have pulled the speedo out of the guage cluster.

when driving the transmission shifts smooth up until i get to OD.
I'm stuck in 3rd.

Could the sensor in the guage be linked to my overdrive?

I bought a new cable, as mine did not have the retaining clip on the guage end (hence being pulled out), but i have not had the time to install it.

any thoughts, I'll be tearing into it soon, but i wanted a little bit of foresight...

I believe the speed sensor IS located in the instrument cluster, and needs the speedometer to be functioning to send the signal to the trans computer. So, yes.
This is truth. Auto trans and cruise control get their speed signals from the speedometer itself. If that does not work, non of your vehicles computers know how fast it is going.
