I just rebuild the transmission and the valve body and the new torque converter. The code set the same

Please help me with how to fix the problem.

Thank you so much

Answer 1

Were is the transmission lines flushed before installing the rebuilt transmission? if not and there may have been metal debri inside the lines causing the same issue.

Take it back to the person who rebuilt it and have them look at it. SL3, SL4 and SLT are the main ones what might be causing the issue.

why was the transmission rebuilt vs replacing it with a used one? was there metal pieces in transmission?
