2001 Nissan Maxima
CEL keeps on going on with this code P0744.
Car was shifting very bad and almost impossible to drive Then the CEL went off with P0744. The ATF was very dirty. Also few years prior the car had over heated briefly. Thought I had saved it. (Bad thermostat)
What I have done is drain a
Atf and put in Lucus and Valvoline synthetic ATF. And it was a lot better immediately. But still not like it should. I also cleared the CEL code at this time
The atf that came out was black/brown, no metallic tint or metal shavings and did NOT smell burned or bad.
It came back in 72 miles. But drove better, continued to drive and at 330 miles after it was even better
600 miles much better
900 miles about back to normal.
I then cleared the CEL and car was driven and felt good. But the. About 2 weeks later CEL came back with P0744.
I was hoping that it was a stuck solenoid or dirty fluid that a ATF service and Lucus might help. And iso far it has helped tremendously.
Should I drain / fill ATF again and add Lucus to get more of the old fluid out. I looked at it and looked dark again with a red tint.
Only looking to keep car for a few more years
Below link is to a video I took of the freeze frame when the CEL came back last
Thank you in advance.

And did all work myself. To save $$
