For the 2002 - 2006 Nissan Altima, the ECM and TCM are both located under the dashboard, behind the glove box. You must remove the glovebox to access these modules. Remember that any yellow wires or connectors are for the air bags. You should probably refer to a service manual before accessing anything electrical/electronic.
The ECM (Engine Control Module) is located under the dash panel, in front of the center console, and to the right of the accelerator pedal.
