Transmission again!

[khaosduke]

I did the cooler bypass and replaced the fluid on my transmission and it seemed to be working fine for a while. No contamination so I bypassed before it could become a problem. It still shifted hard sometimes but the new fluid seemed to be a band aid of sorts for a bit. Finally now there is a code being thrown P1754 for the IC solenoid in the control module.

Looking over the service guide it's something I feel I could do myself. However the problem seems to be finding the part!

Also, does anyone know how to identify which model of TCM you need for your pathfinder, I have an 05 LE 4wd. But there seems to be between 2-3 slightly different models made for that year. Or is this something I'm just going to have to open up to see?
