So I bought their noise filter a while ago because I had the torque converter lock and unlocking problem but I managed to band aid it for a while by just resetting the APPS. I didn't install it because I was hesitant on tapping any wires but I had gotten to the point where the APPS reset wasn't doing the trick so I decided to install it. The whole time I was thinking it wasn't going to work and I would have to purchase a new APPS. Well turns out it works and I'm sure it's all in my head but it seems to shift different but better. I don't know but I just love it and for $50 you can't go wrong. Certainly beats a new APPS. The install was extremely easy. The hardest part was getting the stupid plug out of the ECM. I figured out you have to squeeze the top and bottom but that was after I broke the tab off the top! It still holds so I am not worried. Just a little upset I scratched the tailgate unloading some steel today but other than that I love still love her! Just wanted to share my experience. THANKS DTT
