The speedometer gears for the TH-2004R will not interchange with any other GM transmission.

The single wire on the drivers side?
The only GM transmission I know with a single wire on the drivers side is the TH-400, it is the "passing gear" activation power wire, the TH-400 "passing gear" is activated by applying 12 volts to a solenoid located inside the transmission through a bulkhead connector located about three quarters back on the drivers side of the 400.

If there is a four prong connector near that same location, the transmission is either a TH-350C (350 with lockup torque converter),the TH-2004R (which you can already identify as you have one there), or the TH-700R4 (which we are accurately guessing it is not).
