My wife's 2005 Dodge Caravan (4 cyl) started making some weird noises and the trans began slipping in first and reverse. Flashes of $1000+ repair bills crossed my eyes when it occured to me to try one of those additives you see at Wal Mart. I figured that at worst, it doesn't make it better and I'm still staring at a new or rebuilt tranny, just out $12 for some "snake oil". Well, guess what.... even as skeptical as I was, I poured the bottle into the tranny and from the moment I shifted the van in gear Wednesday, the slipping stopped and has actually had a much firmer feel shifting through all gears. Now, I'm hoping that this "fix" will at least buy me another 6 months, but I'm still skeptical. Has anyone had a similar experience, and if so, how long did it make your tranny last?
