A Solution for Automatic Transmission Repair Today, we’re introducing SUPERNANO Transmission Restorer, specifically designed for automatic transmissions. It effectively addresses issues such as sluggish shifting, vibration, and gear slippage. By enhancing shifting performance and reducing power loss, it helps restore the transmission to optimal condition, nearly doubling its service life. Using this restorer is very simple: first, replace the original automatic transmission fluid filter, then mix the restorer with the transmission fluid, and finally pour the mixture into the transmission. This 2007 Stepwgn has clocked exactly 100,000 kilometers, and the owner has consistently felt that the response during acceleration and gear shifts was a bit sluggish—it was definitely time for some transmission maintenance. Initially, the plan was simply to change the transmission fluid, but after a friend recommended a combination of machine-flushing the transmission and adding SuperNano Transmission Restorer, which had previously improved his transmission’s responsiveness and extended its lifespan, the owner decided to give it a try. To achieve better results this time, the owner used a transmission flushing machine to thoroughly drain and clean out the old fluid. This is because a standard drain-and-fill procedure typically only replaces about half of the transmission fluid. The process using the flushing machine was also very simple and took about ten minutes to complete. After completing the entire transmission restoration process, the owner immediately took the car out for a test drive. Within just a few minutes of driving, a noticeable improvement in the transmission was already apparent. The feel during acceleration was more solid than before, with no more of that “slipping” sensation, and gear shifts were exceptionally smooth—the jerky sensation experienced during previous shifts had been significantly reduced. Because the load on the transmission was lighter, both engine noise and vibration were reduced as well. The owner noted that adding the transmission repair additive this time resulted in significantly better performance compared to simply changing the transmission fluid in the past.
