I’m sold on trans service every 30,000 miles. I used to get BG treatment performed by my dealer for my trans on my then new 2013 Charger Daytona. Not the same trans but BG offers a 150,000 mile extended warranty including labor and parts up to $4,000 if you use their products. What I’m getting at is their warranty is good only if you keep up the trans service every 30,000 miles. The factory service schedule doesn’t call for that but BG requires it. As far as BG is concerned, I never had a trans problem but I did have a roller lifter go bad at 144,000 miles. I did the BG oil treatment every 5,000 miles. They covered me for a $2,400+ bill at the Dodge dealer with no questions asked…of course my dealer provided the service records showing I had my oil changed every 5,000 miles or less with the BG product. I also did my rear differential and fuel system with BG products. BG may not be be for everyone but it was worth it in the end on my car because I knew I was going to put more than 100,000 on it in 3 years.
