Low coast brake Solenoid???

I have a 2005 4.0 2wd Pathfinder having trans issues. I have a code of P1774 Low coast brake solenoid.
Question is I see few different options for replacements - where and/or how do I find what "ohm" is needed?
Also - where can I get a replacement at? RockAuto is out of stock and has been for awhile now.

Thanks in advance!

Iím now expert, but there are some things that Iím scared to skimp on. Things involving brakes fall into this category. Iíve been burned a few times.

Usually, the only time the solenoids go bad is when they get contaminated with "sludge" due to the engine coolant/ATF cross-contamination that occurs because of the "infamous" radiator integral trans cooler failure. When AT solenoid codes trigger that are not due to the cross-contamination issue, many time it's not the solenoid but the pin track for the circuit that cracks and breaks. The YouTube vid I linked below gives a lot of good information regarding the RE5R05A valve body. At around 15:00, it will show a picture of a broken pin track and discuss it. These pin tracks can be repaired with some competent soldering:


BTW, I believe your Pathfinder has the 20-40 Ohm (a.k.a. "High Ohm") Low coast solenoid. The "Low Ohm" solenoid was used in Infinitis, only, if I'm not mistaken. Cobra Transmissions should have that part, if you need it:
