I'm not mechanically inclined in the least, but I would say this repair was quick and easy.
I followed the instructions that came with the part and I watched the video on YouTube.
Everything went smoothly until I put the detergent cap back on. It was rotating just fine, but the detergent door latch wouldn't stay shut. Neither the video nor the instructions indicated this was normal behavior until you get the door put back together, so I struggled here for a bit and took the lever on and off about 6 times. (Which added significant time to my repair.)
Finally, I said "Well, let's see." and I put it back on the door... tada! Everything was peachy.
Outside of that, it was a really easy repair.
