TCM PROGRAMMING
I have this Pathfinder that has been touched by 4 other
shops including a Nissan dealer. It has had the radiator
replaced (looks fairly new) and the transmission rebuilt
(hearsay) with old valve body still installed. Still had a
trans problem and then valve body got replaced (hearsay)
with probably a used unit. Truck was taken to Nissan and
they said it was a bad transmission but sadly (according to
the service writer) they went to move it, it struggled to
move (my thought is maybe in limp mode starting in third
gear) and no scan tool connected to it and customer paid an
hour labor. So now it's my turn and I have driven down the
street (feels like it's in third gear). ECM no codes. TCM no
codes. Some of the data in the TCM is not right like a
wiring problem, but no codes has me being cautious. Fuses at
the fuse blocks are good and I am on to the trans to start
with power and grounds and communication lines. My first
question is can the TCM scavanged from a different vehicle
and programmed to another. My second question is does
programming take place on CAN bus or K line? I would be
programming the J2534 way not the Consult.
