Hi @ Jr Brantley,

Here’s a link to the automatic transaxle repair section from the service repair manual for a 2001-2002 Nissan Altima.

Scroll to p.AT-15 to view the location of the TCM (transmission control module) if this is what you mean.

It is in the same location for a 2004-2005 Nissan Altima so presumably it will be the same for the 2003 model.
