Problem with speedometer and odometer

Hello.
I have a 00 saturn SL200 that I let sit for a few months because i
needed a new transmission. After I changed the transmission m
speedometer and odometer stopped working. I'm not sure if it's a wir
that lost connection or a problem with the actualy instrument cluster
The rest of the gauges seem to work. Does anyone have ideas

 

Was the battery good after sitting or did it need to be charged. I had
a dead battery last year and after it was replaced, my speedometer
did not work....turn out that the ECM lost some data and the data was
needed for the speedometer to work properly. They charged quite a bit
to reprogram the module. Good luck...

There should be some kind of speed sensor on the trans, output side to
give the PCM info to send to the speedo. Maybe it is not hooked up or
is bad in the new trans.

If the speed sensor is defective or unhooked, you should get a light,
or sometimes the trans wont shift because the PCM doesn't know what the
road speed is. James
