Scanguage 2 code p2757

Well, yesterday my 05 tacoma threw up this code on my way home yesterday.
I have researched it and it seems to be associated with the transmission torgue converter. I've reached out to my Toyota mechanic on whether I can drive it or not, and what to do. I took the day off so I dont .she it worse.
I had him add some shudder fix last summer and the shudder stopped but came back.
Lately, I've noticed when I put it into park, it feels like it rolls a couple inches.
My truck has 297k original miles (had to get the transmission replaced around 170k miles with a used one). I'm not at all in the position to get a new truck and hoping for the best.

 

How often do you do drain and fills?

 

I need to research p2757 more, but my first guess (and an easy fix) would be to do a proper fluid level check.

Shudders can be caused by low fluid. And if the check procedure is done wrong you can easily be low on ATF.

 

I have the fluid changed every 2 years.

 

Gonna bring to my mechanics house this afternoon and drop it off. Wish me luck

 

No offense but if its the same mechanic who has done the past flushes I wouldn't exactly trust him to get the check procedure correct
