Where is the tcm on 1995 maxima?

[samm895]

My 95 maxima se has code p0725 for engine speed signal error and possible tcm fault. I don't know where it is. I thought it was under center console, but all that is under there is srs airbag control. Car runs n drives great, but tachometer doesn't work at all- stays on zero no matter what. I also have p0325 code for knock sensor, but from what I have heard it could be my o2 sensor. I am not going to take car to dealer to give me a B.S. diagnostic and charge me tons of money, so I need help. Any one else have similar problems?

Welcome to NICO.

The TCM is located under the center console toward the firewall. See picture on page AT-37. http://www.nicoclub.com/FSM/maxima/1995/at.pdf

The knock sensor code means the knock sensor is bad.
