2012 Raptor Transmission Noise / Issues

[laselvasurf]

My brother's recently purchased 2012 Raptor is making a weird sound and "lurching" a bit when shifting to and from 4th gear. Here's a link to the video. The code it's throwing is: P0741. Has anyone experience a similar issue / sound? The truck has 200K+ on it, so it may just be due for a transmission.

He bought the truck about a month ago and had the transmission filter and fluid replaced then. The issue was happening before that, and has gotten worse slowly after.

Well, I had the po741. I replaced the square seal between the valve body and the case. I also replaced the separator plate between the 2 valve body halves, a shift solenoid, put in a cooler bypass, and shift improvement kit . That was 3000 miles ago and no problems since
