Truck would not start.  Found a low voltage @ the starter relay inside the IPDM.

Replaced the IPDM with new updated model.  No change.
Ran check on the a/t assembly wiring harness for the can lines...came back @ 61...right inside the range -- FSM states that if harness is good...TCM needs replacement.

Inside the trans..and on top of the TCM (after removal) found milky white build up (assuming now that water mixed into the trans oil from the cooler hose/radiator.

Anyone have any experience on this...

part numbers for the TCM
and what are the chances that the Trans is shot? 

after jumping the starter relay...the truck will start and drives great in reverse.  No o/d switch reading, etc. and does not drive safe limp mode likely in 5th gear.

--give me a shout if you have done this job or have anything to add!1


If i broke it, that means it wasn't built right.

The cooler in the rad has gone bad allowing coolant into
the trans. Yes the trans is NG(unless you can find someone
to rebuild it) Nissan dealers replace them. You might want
to call your dealer because they extended the warranty due
to this concern.
