Ok so i just got a 96 cherokee up and running but it wont shift. I can manually shift it to 1st then to the 3rd gear but drive goes straight yo 3rd or 4th. I noticed theres a connector hanging down under the passengerside dash that looks like a computer connector. My question is where is the transmission control module on these? I think mines missing haha Picked it up it was sitting for a while and got it running healthy but i need to get that fixed. Thanks in advance.

 

Heres what the connector looks like

 

That's the plug for the TCU!!!!
Look up under the dash above the plug.
