Hey everyone, I just finished my 6.0/4l80 swap and the trans is not working properly. It has reverse and second gear. Manually shifting also does nothing. It just stays in second. I wired it using this scematic to run on a 4l60e tune.



That is all I have done. I have not modified the tune at all. Any help would be appreciated since this is my first 4l80 swap.

 

Well I thought I would do a follow up if anyone else runs into this problem. I set the codes to no report and it still didn't work. From there I went to the relay. I found that it didn t have power. I had not spliced into the right pin to pull power for the relay. Pin e was more of a pink wire on my truck. lthough the wire I spliced was red, always check the pin letter not the color.
