2011 Maxima SV - 124k miles - Daily Driver

I have been experiencing some transmission issues since we had snow here a week ago. Went to pull codes at AutoZone and received:

p0744 - Torque Converter Clutch Intermittent
p0725 - Engine Speed Sensor
p0826 - Manual Node Switch Circuit
p1701 - TCM Power Supply

My research for similar codes has shown that I may need a new transmission (hope not), I just don't know where to start on getting a fix.

Has anyone experienced any of these codes.

Side Note: I had similar issues on a 5th Gen Maxima and replacing the Vehicle Speed Sensor fixed my issues. Would the same work here??

Any help is appreciated. Thank you.

 

start cheap and work up if you can not bring it to a mechanic.You might buy a few parts but mechanics are crooks and will replace the cvt,

 

I agree with blackmax...start with the basics. When was the last time you did a drain and fill and/or replaced your NS-2 filter? If it has never been done, it MIGHT help but I have never heard of or seen those codes.
