How-to: change the factory TCM software from the automatic transmission Jatco RE5R05A JR507E installed in the Nissan Pathfinder R51.
Vehicle Model: Nissan Pathfinder R51 2.5L YD25DDTi AT dorestayl 174hp 2005Y software number 31020-WL60A
31000-4X04A R51_08MY_YD25DDTi (High) _EUR_4WD;
31000-EB30C R51_05MY_YD25DDTi (High) _EUR_4WD;
The first 5 characters of the firmware:
310 2 0 – 2 WD.
310 0 0 – 4 WD.
According to RE5R05A, the question is closed, after installation on the car everything works correctly.
With a change of software, things are easier here, on the CAN bus it is easy to read / write.
In general, everything worked, but there were kicks during the shifts, different torques
in the software for shifts affected , the gear shifts were incorrect, at high speeds, which is not very good for a diesel, etc.
Here is such a beautiful TCM unit , all in oil, shiny and tasty smelling.

After these frauds, the unit is sealed, installed in its rightful place, the cut tracks are welded together and the back cover is latched.
I connect Nissan Consult-3 , I see the required version of the software:
On the U1000 and P1772 can not look – TCM on the table and nothing but the Consult is not connected to it.
