Customer Question

Where exactly is the TCM on a 2004 Nissan Quest SE? I see the BCM under the triangle glove compartment but can't find the transmission control module. NISSAN dealers can't seem to know and I doubt it is inside the transmission. Please help.

This' the passenger side? And do I have to remove the dashboard?
Expert:  Ron replied 1 year ago.

You should be able to access it with the dash in place.

Besides the TCM and Camshaft Position Sensors, what is another common cause for the transmission to stall?
Expert:  Ron replied 1 year ago.

What do you mean when you say it stalls? Are you getting any fault codes setting?

Customer: replied 1 year ago.
There are no codes. When I start and drive the car runs for a few seconds then it revs up as if the transmission goes into neutral. I usually have to wait a few minutes before firing it up and move again. The car runs for 5-10 secs approximately.
Expert:  Ron replied 1 year ago.

If its not setting any fault code then in most cases the problem is internal. In most cases if its electronic the TCM will set a fault code and or codes.

I have one more question, does a TCM from a 2003-04 Maxima SE fit a 2004 Quest?
Expert:  Ron replied 1 year ago.

No it will not work and the programming will be complete different, you are going to need A Quest module with the proper programming for it to work.

Codes are U1000 and P1726, what does that means?
Expert:  Ron replied 1 year ago.

The code U1000 is a Controller Area Network Line Malfunction - Automatic Transmission concern.

Nissan has a service bulletin for this code that deals with a bad ground to the Computer, see it in the link below.

The code P1726 is a Electronic Throttle Control System concern and Nissian say before addressing this code the U1000 codes needs to be addressed.
